The Cooper Discoverer STT Pro is a mud-terrain tire that's designed for use on Jeeps, SUVs, and light trucks, and offers drivers increased durability, strong on- and off-road traction, and protection from debris and sharp rocks.
Features & Benefits
- Mud-terrain tread
- Raised White Letter or Black sidewall depending on the tire's size
- Backed by Cooper's 45-Day Satisfaction Guarantee and Limited Warranty (restrictions and limitations apply)
- Robust lugs and deep biters are responsible for great traction over muddy, sandy, and rocky surfaces as they work with Earth Diggers Technology to dig deep into dirt and mud
Not all drivers of vehicles with mud-terrain tires consider only off-road traction. Some drivers look for balanced tires that are also good on pavements and ensure a balanced performance both on- and off-road. Fortunately, the Cooper Discoverer STT Pro is designed for good on- and off-road traction, featuring a unique rubber compound and 3 prominent ribs of equal sizes. All 3 ribs of this mud-terrain tire feature ingroove notches, offset sides, and sawtooth edges for enhanced gripping ability in challenging conditions. The Rock Climber Sidewall Technology allows the tire to conquer difficult obstacles, while the Stone Armor Technology ensures protection from sharp rocks and debris. The Discoverer STT Pro is highly durable, featuring the Armor Tek3 Technology. Some of its compatible vehicles include the Chevrolet Silverado 1500, Toyota Tundra, Jeep Wrangler, and more.
Mud Terrain tires offer drivers traction on off-road terrains such as mud, dirt, sand, gravel, and rock, and are commonly used on CUVs, SUVs, light trucks, and jeeps.
Designed for use on light trucks and SUVs such as the Ram 1500, Ford F-150, and Chevrolet Silverado. Light Truck tires are strong enough to support a truck's heavier weight and whatever else is being hauled or towed.
This product is not covered by a manufacturer’s treadlife warranty.
The maximum carrying capacity for a tire determined by the manufacturer (Single wheel applications / Dual wheel applications).
Maximum speed capability to safely carry a load for an extended period of time.
The maximum load carrying strength at the specified inflation pressure, also known as ply rating.
The side of the tire between the tread and rim, with cosmetic branding as well as information about the tire including manufacturer, model, size, etc.
Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.
The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.
An identifier of a particular tire line and size combination assigned by the tire manufacturer.
Tread design (or tread pattern) can affect handling, traction & noise for different driving styles & road conditions.
Shipping weight (lbs)
The measurement of width from a tires inner sidewall to the outer sidewall.
The range of widths the rim of the vehicle can be for this tire to be safely mounted on.
The diameter of a tire that is inflated without any load applied.
