Deep Snow and Mud Performance

The Cooper Discoverer S-T Maxx shines when it comes to tackling deep snow and mud. Its chip-resistant tread compound and unique angled ply construction give the tires better grip and stability on slick surfaces.

You'll also find the sidewall and tread area have been reinforced, providing enhanced resilience against punctures and impacts on harsh off-road conditions.

The tires also sport stone ejector ribs that help prevent rocks and debris from getting lodged in the tread. In our experience, we've found these features significantly boost our vehicle's performance in snowy and muddy situations.

Highway and City Driving

This tire will not only excel in tough terrain but also provide a comfortable and smooth driving experience within city and highway environments. When driving on dry pavement, the proprietary cut and chip-resistant tread compound ensure optimum traction.

And, while the tires aren't specifically designed for winter traction, they still perform well in the rain due to the combination of their tread pattern and water evacuation channels.

One of the highlights is its low noise characteristics, making long drives on the highway or daily commutes within the city more enjoyable and comfortable. The tires are also available in various load ranges, making them suitable for light truck vehicles such as pickup trucks, SUVs, and commercial vans.

Tire Durability and Lifespan

Tread Wear

The Cooper Discoverer S/T Maxx tire has proven to be quite a durable and long-lasting commercial-grade traction tire. We've found that its proprietary cut and chip-resistant tread compound really holds up well on various terrains, including gravel roads and tough terrain.

The tread area and sidewall are designed to enhance traction under mixed driving conditions, making it suitable for high-powered torque vehicles. Tire size and load range can also affect the wear, but generally, the tire offers consistent performance on dry pavement, snow, ice, mud, gravel, highway, and more.

Its unique angled ply construction and stone ejector ribs further aid in prolonging the tire’s life by reducing tire impact forces and protecting against punctures and debris.

Aging Resistance

These tires are not only built for tackling harsh off-road conditions but can also withstand the test of time. The sidewall and tread area are both resistant to aging due to the construction and materials used.

The Cooper Discoverer S/T Maxx features a 3-ply Armor-Tek3® carcass construction, which adds strength and durability to withstand daily wear and tear.

Cooper Tires ensures the tires maintain their low noise characteristics and maintain reliable performance in various terrains, including winter traction. The unique tread features and compound have been designed to provide good grip and stability, even on the toughest terrains.

Intended Use

The Discoverer ST Maxx shines in off-road conditions thanks to its superior traction and durable construction. If your driving involves a significant amount of off-roading or driving on rough terrains, these tires could be a valuable investment.

However, they also offer decent on-road performance, providing a blend of comfort and durability that can handle highways as well as trails.

Price & Value

These tires are competitively priced and offer good value considering their longevity and performance across various conditions. They may not be the cheapest option on the market, but their durability and versatile performance can result in lower long-term costs.

Noise & Overall Comfort

While they offer relatively quiet and comfortable driving for a mud tire, they might not be as quiet or smooth as highway or all-season tires. If a majority of your driving is on paved roads and comfort is a top priority for you, you might want to consider other options.

Durable Construction

Central to the durability of the ST Maxx tires is the innovative Armor-Tek3 carcass construction. This features a full 3-ply carcass, which provides exceptional resistance against damage from off-road obstacles like rocks, debris, or rough surfaces.

In addition to the robust construction, these tires also feature Stone Ejector Ribs that help to prevent stone drilling. Stones that get trapped in the tread can cause significant damage over time.

How Many Miles Will The Cooper Discoverer S/T Maxx Last?

Under typical conditions, the Cooper Discoverer S/T Maxx is known to last anywhere from 50,000 to 65,000 miles. This is a good lifespan for a tire, especially one that is designed to handle off-road conditions.

As a commercial-grade traction tire, the Discoverer S/T Maxx is suitable for high-powered torque vehicles and light trucks. Its unique angled ply construction provides added strength and durability, making it an excellent choice for use in harsh off-road conditions.

The tire boasts a load range E rating, making it great for tackling tough winter terrain. Confidence in this tire's winter traction can be attributed to its silica-enhanced compound and sipe design, allowing it to tackle snow and ice on the road easily.

The Cooper Discoverer S/T Maxx tire also offers:

  • High grip for harsh terrains
  • Low noise characteristics for a more comfortable drive
  • Reinforced sidewalls for increased protection and longer wear
  • Cornering stability and enhanced traction

These estimated mileages are based on normal highway driving conditions and regular maintenance. If you frequently drive in harsh off-road conditions, the lifespan of your tires may be less.
