First, A Bit of History

Buick used the “Somerset Limited Edition” name as a trim level package for 1980 - 81 Regal and advertised this mid-sized upscale luxury car as a first and only edition. The officials expected that a limited production count number would attract consumers to impulsively buy the car, thinking it would be a collector’s item. The two-tone paint and upgraded interior made the car easily recognizable, and consumers seemed to be intrigued with the fresh look. Buick even threw a free umbrella hidden behind the driver’s seat pocket.

For 1985 - 87, Buick decided they needed an alternative to the Buick Skylark (sales for that car were dismal). To attract attention, they advertised the car as an affordable luxury sedan and tried to convince the public that the amenities they longed for were within their reach. The Somerset was fashioned after the Skylark (in other words, the designers got lazy) and presented a coupe using the N body as a separate entry into the Buick lineup. They equipped the Somerset with a basic rough-riding Ironhorse Duke four-cylinder engine, which generated only 92 horsepower. Still, they were pitched as fuel-efficient (it saved on gas but had no power to speak of). This effort was in response to a concern about rising gas prices (gas had increased to $1.13 per gallon, but only five years before, consumers had been paying $0.67).

There were some exciting novelties about Somerset, namely the digital instrument panel it offered. However, the car’s charging system could not handle the load, and the dashboard failed more times than it worked. In addition, the stereo system was supposed to be state of the art. Still, Buick installed it directly above the heating and ac controls, which meant it was almost impossible to remove or replace with aftermarket systems. Buick built a car with no horsepower, no electrical functions (consumers could not tell how fast they were going or how much fuel they had left in the tank), and had no stereo. This Buick looked like every other Buick on the road (albeit slightly smaller). The American public refused to be conned by the new offering, and those who purchased the new car took them back to the dealers shortly after purchasing them - (my Gramps being one of them - he owned a Somerset for less than a week - the dashboard blew three times). After that, the car sales were so bad the first year that less than two years later, it was discontinued in 1987.

What Are Some Considerations When Purchasing Vintage Tires?

There are various things to consider when purchasing a tire for an older car. While tires range in size, appearance, performance, and price, a good set of tires can go a long way to making your car the highlight of the show or your garage.

Check Your Owners Manual

To ensure the exact tire size you need for your particular Buick Somerset; you should consult the original handbook. Most owners' manuals have detailed information concerning the correct tire dimensions for your car.

Determine Your Plans for the Car

If you are a purist and are restoring the Somerset as close to the original as possible, you can search for used tires that will make the car look period ready. Finding used tires can be mind-numbing, particularly as limited as parts are for this Buick. Purchasing older tires is time-consuming and generally not considered the best option. Even though you can brag about your car having period everything on it, most old tires will be plagued with dry rot on them, as to be little good. (Unless you plan on mounting them on and taking them off before and after every show). Be careful if you go used - check with your dealer, part dealer, or tire center for availability.

Even if you plan to take your car to shows and compete for judges’ points, you will want a tire that looks as original as possible. Many companies like Coker, Diamondback, and Vintage Tire specialize in making tires that look very close to OEM tires. The tread patterns will not be the same as what might have been on the original Buick, but at a glance, the tires will look right and probably won't cost you any points. These modern tire look-a-likes will allow you to drive them during cruising nights and come in all whitewall sizes. Many enthusiasts who frequent car shows and rallies love the alternative and use these tires as their go-to. The problem with vintage tires or lookalikes is that they are much more expensive than just an all-season radial.

For everyone else that just wants an old car to cruise around in now and then but doesn’t care about what looks exact, then [urchase a set of new all-season radials that perform well, offer a good ride, and last. Be sure to drive your beast every couple of weeks just to keep the tires from dry rotting.

Decide What Kind of Budget You Have

Car tires can range widely in price, so it is best to figure out your budget ahead of time. You will likely always spend more than you want, but if you don’t care about being car show-ready, then several affordable tires are out there. Remember that most tire installers charge extra for mounting and balancing when figuring out your budget.

Consider the Reputation of the Manufacturer

There are a few big names in the vintage tire business. Coker Tire, Diamondback, and Vintage Tire Company are all reputable vendors of tires for antique vehicles. They have excellent return policies and are known for their customer service. While you may be able to find tires at a local or discount tire vendor, be sure to read the reviews wherever you decide to purchase. Remember that many companies offer customers freebies for positive reviews so take the great reviews you read with a grain of salt. Since negative reviews tend to be more truthful, look for less than stellar reviews. You should look for patterns, if more than one client mentions the same concern, it might be a clue to an inherent problem.

Don’t Forget About the Spare Tire

The Buick Somerset came with a full-sized spare, so it won’t just be four tires you will be buying if you need to replace them. The last thing you want is to have a flat tire and then discover a flat or dry-rotted spare you cannot use in the trunk.

How Can I Tell If the Tires Need Replacing?

The old penny test still applies here, but it isn't the only thing to look for when examining tires on a vintage car. Signs of cracking, separated tread, or faded color (dry rotting tends to break down the chemicals in rubber and makes the tires look grey or have a white powdery color). If you see cracks or bulges on the sidewall (bulges are signs of weakened areas that are prone to blowing out), then it's time to replace the tires, no matter what Abraham Lincoln says.

How Do I Tell If My Tires Need Replacing?

Well, the basics apply here, but for the novices who are just getting started, here are a couple of helpful hints.

Know Your Tires Birthday

The tire age has a lot to do with whether a tire is experiencing dry rot. If the tire is older than six to ten years, it has probably been exposed to some dry rot, particularly if the car has been exposed to the elements. The way to determine the tire's age is to look at the tire's sidewall and read the US DOT number stamped on the sidewall. Every tire from 2000 on has this four-number sequence which indicates the week (1-52) and the Year (2013 would read 13).While this won’t help determine the date of original tires on a 1985 Somerset, it is useful information.

Look at Your Tires

A good visual inspection every couple of weeks is a good first step. You want to look for signs mentioned above, brittle, cracking, discoloration, or bulging. If the tread appears to be separating from the base of the tire, then you are a definite candidate for dry rot.

Drive the Car

If tires sit, the rubber compound of the tire tends to do two things, get colder, and settle in the direction of the bottom of the tire. This position weakens the other areas of the tire and makes them prone to cracking. A good drive will rotate the tires, warm the rubber compound and keep the rubber evenly distributed around the tire's circumference.

Store the Car Correctly

If you want to maximize your tire life, then store the car away from direct sunlight and heat, which are very detrimental to tire life. A good tarp can cover the car, help keep dust and debris off, and preserve the paint and tires. (Just try not to use the hood of the car as an extra workbench like my father often did because then you’ll decide that clearing it from all the boxes on top of the tarp is too much trouble, and you won’t be prone to driving anything).

How Long Can I Expect Tires to Last?

Most tires will last a long time if not driven daily. If you drive your Somerset on the road constantly, that continual contact with the pavement will wear the tread down, and you need to keep a close eye on the tire’s mileage.

Most car enthusiasts recommend replacing vintage car tires every five to six years, assuming care is taken to avoid dry rot. You should be good if the car doesn’t sit for a prolonged time but is driven enough to keep the rubber from settling or deteriorating. If the car sits for more than three months without being driven, then Mr. Dry Rot is likely to be a close companion.

What If I Need To Drive on a Tire that Appears Dry Rotted?

The short answer is don’t do it - ever. However, if you need to drive the car to a mechanic or onto the back of a wrecker, then as long as the tires have air, you should be able to do so. If you have to drive a car with dry rotted tires, keep your speed low, flashers on, and have someone follow you. The last thing you want is to place yourself or anyone else on the road in harm’s way.

Is There a Secret to Saving Money on a Set of Tires?

While nobody wants to pay more for tires than they need to, there are a couple of things you can do to save some money on your next set of replacement tires.

Dare To Compare

Do your homework to see if more than one tire dealer carries the brand and type of tire you have selected. If you find the tire listed more cheaply online, consider ordering them from the internet site and taking the set to a dealer or mechanic for installation. Most car repair centers will charge around $20, give or take, for mounting and balancing. If you don’t want to order online, take the image of the ad to the car center and ask if they will match the price, chances are they will, so they can keep your business.

Haggle a Bit

You don’t want to be a jerk, but if you don't ask for a discount, you won’t ever get it. Parts guys are used to negotiating, and the car center might be willing to discount tires if you add another service. The discount might not be much, but every little bit helps.

Use Coupons or Other Discounts Offered by the Car Center

If the car center offers a coupon for a certain percentage off a repair, use it. Take advantage of senior or military discounts that could save money. If you don’t see anything offered, ask or find a shop that will provide a reduction.
