Understanding what tire size is right for your vehicle is important in making the right choice when it’s time to replace your worn-out tires or buy new tires.

You’ve probably never paid attention to the string of letters and numbers on the sidewall of your tires. Well, it’s a goldmine of information as far as your tire size is concerned. Whether you’re looking to replace your current tires or want to ensure that your current tire matches your vehicle’s requirements, it’s of great importance to know your tire size and how tire sizing works.

Deciphering the numbers and letters on the sidewall of your tire is essential. Tire sizes begin with a letter(s) that shows the type of vehicle for which they’re designed for. You’ll also find the tire’s width, aspect ratio, and rim size; all of which make the tire size.

Many drivers seem to offer little thought to their tire sizes and wheels save for cosmetic purposes. Needless to say, the wheel size of your vehicle and the tire sizes that you put on them is of great importance. This article, therefore, covers everything you’d want to know about tire sizes. We’ve done comprehensive research on various tire sizes while highlighting the best tire sizes for various car models. To verify that this information is accurate, we consulted various tire brands including Bridgestone, Yokohama, Michelin, and Goodyear.

What Does Tire Size Mean?

A tire size specification is generally outlined by the numbers and letters that are imprinted on the sidewall of your tire. This means that your tire size is not defined by a single-digit but a series of numbers and letters that show various specifications including vehicle type, aspect ratio, width, speed rating, tire construction, rim diameter, and load index.

How to Read American Tire Size?

The U.S. is one of the few countries in the world that doesn’t use the metric system as a national standard. But even with that the metric system is still intertwined in our everyday lives and is critical in tire sizes. This means that all tire sizes in the United States generally follow the metric system that shows the metric system by showing the tire diameter in inches, tire width in inches, and wheel size in inches.

How to Find Tire Size

One of the easiest places to find your tire size is on the sidewall of the tires. You’ll find an imprinted series of numbers and letters that show various tire specs that are related to the tire size.

You can also find the appropriate tire size for your vehicle on the door jamb of the driver’s side.

How to Read Tire Size

Determining the correct tire size for your vehicle should be fairly simple if you know where to find the information. Well, all the information that you require is available in the owner’s manual for your vehicle, on the driver’s side door jamb, on the glove box, on the gas tank hatch, or on the tire itself.

Assuming that your current tires are the proper size, you can easily find the data in a string of letters and numbers on the sidewall of your tires. You, however, have to know how to interpret what each number and letter stands for.

Let’s use the following tire size as an example: P225/70R16 91S.

how-to-read-tire-size

Now, let’s decipher each of these letters and numbers and what they stand for. This brief video shows how to read the tire size numbers.

Tire Type

The tire type is generally the first letter in the code. Its main aim is to tell you what class of tire it is. In most cases, you’ll see the letter “P”. This letter stands for “P-metric” which essentially refers to tires that are designed to a particular standard within the United States. They’re intended for passenger vehicles including cars, crossovers, SUVs, minivans, and light-duty pickup trucks.

You can also find tires beginning with the letters “LT” instead of “P”. This stands for “LT-metric” which means that the tires are designed for “Light Trucks”. These types of tires are designed to be used in vehicles that can tow trailers or have a load capacity of ¾ to 1 ton.

You might also come across tires beginning with “T”. This stands for “Temporary” and is generally found in spare tires. There’s also “ST”, which stands for “Special Trailer”. These types of tires are meant for trailers including boat trails, fifth wheels, utility trailers, and other travel trailers.

Width

Also known as the section width, the width is the first 3-digit number that appears following the letter(s). It is in millimeters and refers to the size of your tire from side to side if you’re looking at the tire from the front. In other words, it’s measured from the outer sidewall to the inner sidewall.

From the above example, the tire has a measurement of “P225”, which basically means that this tire is for a passenger vehicle and has a width of 225 millimeters.

Aspect Ratio

The tire’s aspect ratio is the next number that follows the slash mark. It’s usually a two-digit number that shows how tall your tire’s profile is. An aspect ratio is generally delivered in percentage and is calculated by dividing the tire’s height off the rim by the width of the tire.

As such, a bigger aspect ratio means that the tire has a higher or taller sidewall. On the other hand, a vehicle with a lower aspect ratio such as 60% means that the tires can offer excellent and better handling performance than higher aspect ratio tires.

From our example, the aspect ratio of the tire is 70.

Construction

The construction of the tire is deciphered by a single letter that follows the aspect ratio. There are two types of tire construction:

  • R – Radial
  • D – Diagonal or Bias Ply

A vast majority of tires that are used in the U.S. are radial tires because they’re the industry standard for most tires today and that’s why you’ll see most tires with the “R” designation. Radial construction typically means that the internal ply cords of the tire are designed in a radial direction and are perpendicular to the direction of travel or the axis of rotation.

Here’s a look at a radial construction.

tire-radial-construction

Radial tires are popular because they offer better road grip, low rolling resistance, comfortable ride, lower gas mileage, and are durable.

Differently, tires with a diagonal or bias ply construction are built with diagonal or crisscrossing ply cords. Also known as x-ply or conventional tires, these tires are commonly found in trailer or motorcycle tires.

Here’s a look at a diagonal construction.

tire-bias-construction

Rim Diameter

The next number after the construction letter is the rim diameter. It’s generally known as the middle number in the tire size. It’s in inches and is meant to designate the rim onto which the tire should be mounted. It’s usually a 2-digit number and shows how wide the wheel should be. For our example, it means that the tire should be mounted on a rim with a 16-inch diameter.

The most common rim diameters are 14, 15, 16, 17, 18, 19, 20, 21, and 22.

Below is a picture depicting a rim diameter.

tire-rim-diameter

Load Index

Load index is the 2-digit number that follows the rim diameter. It indicates the maximum load that the tire can comfortably support when the tire is properly inflated as recommended by the manufacturer.

The load index is in pounds and corresponds to the specific load capacity listed in an index and usually ranges from 65 to 150. In our example, the tire has a load index of 91, which means that the tire has a maximum load capacity of 1,356 pounds.

This table shows the various load indexes with their respective load capacities in pounds.

Speed Rating

The final letter in the series shows the speed rating of the tire. This indicates the maximum speed at which it’s safe to travel on the tires. In our example, the tire has a speed rating of “S”. This means that it’s rated for up to 112 mph. It can, therefore, handle heat better and provide more control at faster speeds.

On the other hand, a tire with a speed rating of “R” can attain up to 106 mph and it’s not perfect for top speeds. All in all, it’s always safe to adhere to the legal speed limits of the roadways.

This table shows various speed ratings with their respective top speed in miles per hour.

To this end, there is a lot of information that goes into reading your tire size. You should, therefore, know what each digit and letter stands for to know exactly the right tire size for you.

What if there’s no Letter Before Tire Size?

If your tire has no letter before the first number, it means that you are using a tire with a metric system popularly known as the European size. Such a tire can be measured in millimeters and may have a different load capacity than an LT or P tire.

How to Determine Tire Size

You probably want to know your tire sizes for various reasons including buying new ones or rims.  While you can use a tape measure to manually determine the tire size, this won’t give accurate results as various specifications go into determining the right tire size for your vehicle.

The best way to figure out the appropriate tire size is by looking at the sidewall of your current tires. You can as well look at the placard printed on the driver’s side door jamb or the vehicle’s owner’s manual.

How Does Tire Size Work?

As noted earlier, tire size includes a couple of specifications that are all important in determining the right tire size for your vehicle. They include vehicle type, aspect ratio, width, speed rating, tire construction, speed rating, rim diameter, and load index.

How to Match Tire Size to Wheel Size

The width and diameter of your tires and rims are two important factors that help in determining the compatibility of the rim and the tire. You have to make sure that your tires and rims are an exact match for each other.

The best and probably the simplest thing to do is to look at the tire size. For example, a tire size of 275/65R18 should be perfect for a 17-inch diameter wheel. You should also keep in mind that matching tire width to wheel width will depend on the purpose of the vehicle. For example, you may have to go with a wider tire width if you’re planning for off-road escapades.

What Size is a 33-inch Tire? 

We often get questions regarding tire sizes that are considered 33 inches, 35 inches, 37 inches, and 40 inches. These figures refer to an old tire sizing system, which is known as flotation sizes. This system is quite different from the modern tire sizing system and this can be quite confusing.

For this reason, the chart below will show various tire sizes and their equivalent tire truck sizes.

15 Inches 16 Inches 17 Inches 18 Inches 20 Inches 22 Inches

The table above shows 40 inches tires.

What Tire Size can I Fit on My Truck?

You’ll find the best tire size to fit on your truck in the owner’s manual. It depends on the specifications of your vehicle, its load capacity, and many other features. The tire size that you can fix on your truck can be determined by the model of your truck as well as the size of the rims. But if the truck is lifted, you can fit tires measuring 37 inches or even 40 inches.

How Long can You Drive on a Full-Size Spare Tire?

If you’ve been wondering how long you can drive on a spare tire, then you’ve probably been driving on it for way too long. But if you can’t get a new tire as soon as possible, then you can drive on a full-size spare tire for about 70 miles.

What Tire Size will Fit My Rim?

The rim of your vehicle and the tire size that can fit in that rim should be closely related. This means that the tire rim diameter that is noted on the sidewall of the tire should be the same as the size of your vehicle’s rim.

So if you’re planning to replace the OEM tire with an aftermarket tire, make sure that the rim diameter on the tire sidewall corresponds to the actual rim diameter on your vehicle.

This table shows various rim sizes and the ideal tire width.

How to Read Tire Size Numbers

Knowing how to read the series of letters and numbers on the sidewall is of great importance, especially when you want to compare or change your tires. The most important thing is to know what each number and letters stand for.

What Size Tire will My Chains Fit?

Also known as snow chains, tire chains are essential in enhancing traction on winter tires in snow and ice. They’re of great importance if you’re planning to drive in locations with heavy snowfall. The tire chains will only be effective if they fit perfectly on your tires. As such, you should know the right size of chains that will fit on your tires.

Tire chains come in various sizes and it’s easy to calculate the chain length based on the number of links it has. The easiest thing to do is to write the code of your tire size on a piece of paper and take it to your local auto shop. Here, the store attendant will check the code and get you a chain link that will correctly fit your tires.

What Size Tire will Sure-Grip SSC Class S Chains Fit SZ331?

Sure-Grip SSS chains are easy-to-install passenger car tire chains that are ideal for offering better traction performance when driving in snowy terrains. As one of the most popular tire chains, you are probably wondering what tire size might fit in these chains.

While it might fit on various tire sizes, it can be most ideal for tire sizes including 205/60R16, 2I5/50R17, 185/80R14, 205/70R15, 215/55R16, 255/35R17, and many more.

What Size Tire Chains Do I Need for My 2016 VW Tiguan?

For the 2016 VW Tiguan, the PW1026 Glacier Cable Snow Tire Chains can be the most ideal option. The chain will perfectly drape over your tire and is easy to install on your tires.

How to Read Metric Tire Size

While measuring tires in inches is quite easy to understand, it can be quite difficult to measure tire sizes in metric. The first figure to use when reading metric tire size is the width in millimeters. You should divide this number by 25.4mm since an inch is equivalent to 25.4mm.

You should then take the rim diameter, which is generally the two digits after the R (construction). The aspect ratio, which is typically in metric tire sizes, is then used to determine the overall height of the tire.

How to Calculate Tire Size

Modern tires come in a combination of metric, English, and mathematical systems that are used to offer tire specifications. This is essential in determining basic tire dimensions. To calculate the overall diameter of a tire, you should multiply the sidewall height by 2 since the tire diameter has two sidewalls. One is below the wheel touching the ground and another one is above the wheel.

This calculation will unusually combine millimeters, percentages, and inches to offer the nominal tire dimensions as provided by the tire manufacturers.

What does the First Number on a Tire Size Mean?

The first number on a tire size usually shows the width of the tire in millimeters.

What Does Nominal Tire Size Mean?

Nominal tire size is generally used to show the tire size that is in writing, especially on the sidewall of the tire. This means that it can be a little different for the actual tire size.

What Tire Size is a 285?

There are various 285 tire sizes. They may differ in rim inches, tread width, and actual tire height. Generally speaking, a 285 tire should have a diameter of 32.7 inches, a width of 11.2 inches, a wheel rim of 17 inches, a sidewall of 7.9 inches, and a circumference of 102.7 inches.

This table offers various rim inches, tire metric sizes, tread width, and tire height.

What Tire Size Fits a 17x9 Rim?

From the above chart, a 17x9 rim can fit is a 235/65R17 tire.

What Tire Size Fits a 15x10 Rim?

The best bet for 15x10 rims is a tire size of 265/50R15.

What Tire Size Fits a 17x8 Rim?

A 215/45R17 tire size can be a perfect fit for a 17x8 rim. You can also consider any tire ranging from 235 mm to 245 mm but you’ll have to deal with added weight as well as fewer options to choose from.

What Tire Size Fits an 18x8 Rim?

The 18x8 rim can either use a 235/40 or a 225/40 tire. Both can fit perfectly well in terms of the shape of the sidewall and can fill the guards slightly better. Better still; the tire diameter is within a perfect tolerance of the stock size.

This sheet will show various tire sizes and their perfect rims.

What Tire Size is 305?

A 305 tire size has a width of 305 millimeters but the other specs of the tire might differ depending on the intended use. For example, a 305/70R16 tire means that it has a width of 305 millimeters, an aspect ratio of 70%, and is ideal for a 16-inch tire. There are also various specs for a 305 tire as indicated in the chart above.

What is 305 Tire Size in Inches?

A 305 tire size is about 32.8 inches and can be perfect for a 16-inch rim.

What Tire Size is 315 in Inches?

The actual tire height for a 315 tire size is 34.6 inches. This tire should be about 12.4 inches wide and a sidewall height of 8.68 inches.

What Tire Size is 275?

Most 275 tires are a perfect fit for rims ranging from 8.5 to 10 inches even though 9.5 inches is considered the perfect rim for a 275 width tire.

What Tire Size is a 315?

A 315 tire size means that the tire has a width of 315 millimeters with an aspect ratio of about 35%. This tire size is generally designed for a 20-inch rim but this may depend on its specifications.

What Size is a 30-Inch Tire?

A 30-inch tire is meant for light trucks and is equal to the 255/70R16 in the P-metric system.

What Size is a 245 75 Tire?

245 75 is generally used to denote a tire size of 245/75R16. This tire size has a diameter of 30.47 inches, a width of 9.65 inches, a sidewall height of 7.23 inches, a circumference of 95.72 inches, and can attain 661.93 revolutions per mile.

What Does the Second Number in the Tire Size Mean?

The second number in the tire size is the aspect ratio. It’s essentially a proportional relationship between the tire’s width and height. If the aspect ratio, which is measured in percentage is bigger, then the sidewall of the tire will also be big.

What is the Biggest Tire Size for My Truck?

With a plethora of options and tires available, choosing the right tires for your truck can be quite challenging. When making this decision, one of the biggest things to consider is the tire size. While each vehicle has the recommended tire size, you can consider getting a different tire size but there are a few things to keep in mind.

Depending on your vehicle’s make and model, you can fit 33 inches tires on your truck that is if it’s not lifted. But if it’s lifted, you could fit up to 37 inches or even more depending on the size of the lift. The only problem is that it will affect your truck’s balance and suspension.

How Does Tire Size Affect Gear Ratio?

You’ve probably been thinking about changing your tire size. Well, you’re not alone and many car owners do it for various reasons. Whatever your reason, you should always keep in mind that your tire diameter, together with your rear-axle gearing, plays a huge role in the final gear ratio as it can affect acceleration and the overall performance of your vehicle.

So how does a larger-than-stock tire affect the performance of your vehicle? It all has to do with the gear ratio. A vehicle is usually designed with the optimum axle gear ratio that can work perfectly with the vehicle’s transmission, engine, and stock tire combination. This is essential in offering a proper balance between fuel economy and acceleration.

So if you install bigger tires on a vehicle while the axle ratios remain the same, your gear ratio will be affected. In short, your engine will be operating below its power band and your fuel economy and performance will be adversely affected.

As such, you should find the perfect gear ratio that matches the tires that you install on your vehicle. It basically revolves around a simple mathematical formula to help you determine the right gear ratio.

The formula should be rpm = mph x gear ratio/tire diameter.

So let’s assume we want to determine the gears that should be installed when putting 32” tires on a transmission. Suppose the gear ratio is 2.08 and the stock tires are 30”. If the vehicle’s engine is spinning at 2242 rpm at 70 mph, this could be:

2242 = 70 x 2.08 x32/30.

If you are not so good with the figures, this chart can make it a lot easier. It will at least give you an idea of the best gear ratio for your vehicle. More importantly, you should discuss your vehicle’s gearing needs with a professional before buying the tires.

What Tire Size Fits a 15x8 Rim?

Tires have flexible sidewalls, which means that a single tire can fit on various rim widths. Needless to say, the width of the rim will influence the width of the tire. For example, a tire will be narrower if it’s mounted on a narrow rim and will be wider if it’s mounted on a wider rim.

The rule of thumb is that for every ½ inch change in rim width, the section width of the tire should correspondingly change by about 2/10 inches. As such, a 15x8 rim should be perfect for a P225/70R15 size tire as the rim is 0.5 inches wider than the 7.5-inch wide rim.

How to Read Trailer Tire Size

Reading the trailer tire size is the same as the way you read other vehicle tire sizes. The image below should offer you a glimpse of what to expect.

how-to-read-trailer-tire-size

From the above image, the tire size of the trailer is ST225/75R15. ST stands for Special Trailer Service. This is then followed by the first set of numbers (225), which shows that the tire is 225 millimeters wide. The aspect ratio is 75%. This shows the height of the sidewall and is 75% of the width of the tire (225), so it should be (75%x225) = 168.5 mm. This tire has radial construction, which is indicated by the “R” in the sequence, while the last set of digits (15) means that it should be mounted on a 15-inch diameter rim.

What Lugs are Ideal for Mitsubishi Montero Tire Size?

The ideal lug nut size for a Mitsubishi Montero is M12x1.5 with a lug pattern of PCD 6x139.7. This lug nut size can be perfect for various tire sizes including 235/70R16, 265/70R15, 285/55R18, 265/40R22, and many more.

What is the Stock Tire Size on a Jeep Wrangler?

The tire sizes of a Jeep Wrangler may vary depending on the model. However, standard factory tire sizes for a Jeep Wrangler range between 15 inches and 17 inches. The tire size of a Jeep Wrangler may be as follows:

265/80R17

  • The 1st set of numbers (265) shows the tire width in millimeters.
  • The 2nd set of numbers (75) shows the aspect ratio of the tire, which is the height of the sidewall in millimeters.
  • The next part (R) shows the tire’s internal construction. The other option is (B) which shows Bias Ply construction.
  • The last two digits show the rim diameter in inches.

How Does Tire Size Affect Speed?

While a larger wheel diameter can make the car faster and offer composed handling, it will most likely result in slower acceleration. This is because a larger diameter wheel makes the vehicle a lot heavier, thereby affecting the required speed during acceleration.

How Does Tire Size Affect Speedometer?

Speedometers are designed in such a way that the torque created by the magnetic field should accurately reflect the speed of the car. While no speedometer can be 100% accurate, it at least gives you an idea of the speed at which your vehicle is running. But when you change the tire size, it can significantly affect the speedometer and how the speed is displayed.

When you install a larger or taller tire, the speedometer reading will become slower than the actual speed of the vehicle. This is because you’ve interfered with the overall diameter of the stock or original tire as the larger tire will have a larger overall circumference and will cause the vehicle to travel more distance per revolution than the original tire.

On the other hand, changing to smaller tires means that the speedometer reading will become faster than the actual speed of the vehicle. This is because the smaller tire will have a smaller overall circumference and will cause the vehicle to travel less distance per revolution than the original tire.

How Do You Calculate Odometer vs Tire Size?

The odometer is an instrument that’s used in calculating the distance traveled by a vehicle. This calculation may be done based on the number of revolutions of the tire. For every revolution that the tire makes, the odometer will register 1 mile.

This means that the circumference of the tire will affect the odometer based on the revolutions that it makes. For that reason, a tire with a smaller diameter will affect the odometer reading more than a tire with a larger diameter.

How Much will the Speedometer Change from Changing Tire Size from 14-Inch to 15-inch?

Have you ever wondered how much your speedometer changes when you mount bigger tires on your vehicle? Well, there’s a formula that you can use to find just how much your speedometer will change. This formula is new tire diameter/old tire diameter*speedometer in MPH.

In our case, it would be: 15/14 =1.071*180 =192.9. This means that your speedometer will change by about 12mph (192.9-180).

How to Adjust Speedometer for Tire Size

The speedometer of your vehicle is meant to give you an accurate estimation of your vehicle’s speed. In most cases, the speedometer is calibrated and synchronized with the vehicle’s stock parts. This means that changing any stock part of the vehicle including the tires could throw off the speedometer and you’ll have inaccurate speed readings.

Generally, if you change to larger tires, chances are your speedometer will read slower than the vehicle’s actual speed. On the other hand, the speedometer will read a lot faster if you change to smaller tires. That being said, you should know how to adjust the speedometer when you change the tires.

Here’s what you should do if you have an electronic speedometer.

  • Check the vehicle’s owner’s manual or other supporting documentation to determine the distance of the test drive that’s required to recalibrate the speedometer.
  • Press and hold the calibration button on the speedometer. You can then start the vehicle and release the button.
  • Press the button again and drive the vehicle to the distance prescribed in the owner’s manufacturer to recalibrate the speedometer.

How Does Tire Size Affect Gas Mileage?

If you want to maintain the right fuel economy, it’s important to maintain the stock tires of your vehicle as recommended by the vehicle manufacturer. This is because changing the tire size can have significant effects on the gas mileage and overall fuel economy.

The idea here is that larger tire sizes will decrease your fuel economy since they are heavier. On the other hand, smaller tires can increase your fuel economy because they’re lighter. This is because larger tires have a higher rolling resistance than smaller tires and will, therefore, require more power, energy, effort, and resistance to get them rolling.

You should also keep in mind that larger tires can help in fuel economy if you’re on a freeway and driving at high speeds. All in all, there are a lot of factors that combine to affect your vehicle’s gas mileage. They include the air pressure in your tires and the tire treads. As such, a combination of good tire treads, the right air pressure, and the appropriate tire size can help in having a good fuel economy.

How Does Tire Size Affect Performance?

The size of your tire does affect various components of your vehicle including noise levels, comfort, fuel economy, and the car’s performance. A tire size with a smaller sidewall height will make the car sharper while also improving handling. While larger wheels can impact the comfort of the ride, smaller wheels make the car feel more comfortable, particularly when driving over rougher road surfaces and potholes.

With that in mind, you should seriously think about what it is that you want to get from your tires before switching to another tire size. If you want to improve the handling and performance of your car, you should upsize the tire size. But if you want to improve on noise, comfort, and fuel economy, then you should downsize on your tire size.

How Does Tire Size Affect mpg?

While several things can affect the gas mileage of miles per gallon of your car, the wheels and tire size of your vehicle may also impact your fuel economy. Having a bigger tire size decreases your fuel economy since they’re heavier. The idea here is that bigger tires have a higher rolling resistance and require more resistance and power to have them rolling.

On the other hand, smaller tires may increase your fuel economy. This is because they have lower rolling resistance and thereby require less resistance and power to have them rolling.
