When I decided to upgrade my truck’s tires, the Cooper Discoverer STT Pro 35X12.50X20 caught my eye immediately. After doing my research and personal testing, I want to share my insights to help you make an informed decision if you’re considering these tires for your vehicle.
Understanding the Size: 35X12.50X20
The numbers in 35X12.50X20 describe the tire’s dimensions, which are crucial for fit and performance. The “35” stands for the tire’s overall diameter in inches, “12.50” is the tire width, and “20” is the wheel diameter it fits. I found that this size is ideal for trucks and SUVs that need larger tires for off-road performance without sacrificing too much on-road drivability.
Durability and Construction
One of the reasons I chose the STT Pro is its reputation for rugged durability. These tires are built with reinforced sidewalls and a tough tread compound, which made me confident they could handle rocky trails and rough terrain. In my experience, the tire’s construction resists punctures and cuts better than other tires I’ve used.
Tread Design and Off-Road Performance
The aggressive tread pattern on the Cooper Discoverer STT Pro is designed for serious off-road traction. I noticed excellent grip in mud, snow, and loose dirt thanks to the deep, staggered lugs and wide voids that help self-clean the tread. This design gave me the confidence to tackle challenging trails without getting stuck.
On-Road Comfort and Noise
While these tires excel off-road, I was pleasantly surprised by their on-road manners. Although they’re louder than highway tires, I found the noise level acceptable for daily driving. The ride quality was firm but not overly harsh, which is a good trade-off considering their off-road capabilities.
Load and Speed Ratings
Before buying, I checked the load and speed ratings to ensure the tires matched my vehicle’s requirements. The STT Pro in this size usually offers high load-carrying capacity, which is important if you haul heavy loads or tow. I made sure the speed rating was suitable for my driving habits, balancing safety and performance.
Price and Value
These tires are not the cheapest option out there, but from my perspective, the price reflects their quality and durability. Considering how well they performed in tough conditions and their longevity, I believe they offer excellent value for serious off-road enthusiasts like me.
Final Thoughts
If you’re looking for a robust, aggressive tire that can handle extreme off-road conditions while still being manageable on the highway, the Cooper Discoverer STT Pro 35X12.50X20 is a solid choice. From my own experience, they deliver impressive traction, durability, and overall performance that justify the investment.
