My Buying Guides on Cooper Stt Pro 285/70R17
When I decided to upgrade my truck’s tires, the Cooper STT Pro 285/70R17 caught my attention. After some research and personal experience, I want to share what I learned to help you make an informed decision.
Understanding the Tire Size: 285/70R17
The numbers and letters in 285/70R17 tell you a lot about the tire. The “285” refers to the tire width in millimeters, so these are fairly wide tires that provide excellent road grip. The “70” is the aspect ratio, meaning the sidewall height is 70% of the tire’s width. The “R” indicates radial construction, which is standard for modern tires. Finally, “17” is the wheel diameter in inches — so these tires fit 17-inch rims, common on many trucks and SUVs.
Why I Chose Cooper STT Pro
Cooper is known for reliable and durable tires, but the STT Pro specifically impressed me because it’s designed for aggressive off-road use while still performing well on highways. I needed a tire that could handle mud, rocks, and rough trails without sacrificing comfort or tread life on pavement. The STT Pro’s deep tread patterns and reinforced sidewalls gave me confidence in tough conditions.
Tread Design and Performance
The aggressive tread blocks and open shoulder design provide excellent traction in mud, snow, and loose terrain. When I took my truck off-road, these tires gripped better than my previous set, reducing slippage and improving control. On the highway, they were surprisingly quiet and smooth compared to other mud-terrain tires I’ve tried.
Load and Speed Ratings
The 285/70R17 STT Pro tires usually come with a load rating suitable for heavy-duty trucks and SUVs, meaning they can handle substantial weight without issue. I made sure to check the specific load index on the tire sidewall to confirm it matched my vehicle’s requirements. Speed ratings for these tires tend to be moderate, reflecting their off-road focus, so they’re best suited for everyday driving with occasional high-speed use.
Durability and Longevity
One of my priorities was a tire that lasts. The Cooper STT Pro is built with a tough rubber compound and reinforced sidewalls to resist punctures and cuts. After several months of mixed on- and off-road driving, I noticed minimal tread wear and no damage, which speaks to its durability. Of course, regular tire maintenance like rotation and proper inflation is key.
Fuel Efficiency Considerations
Because these tires are wider and more aggressive than standard road tires, they can slightly reduce fuel economy. I noticed a small drop in miles per gallon, but it was a trade-off I was willing to make for the off-road capability and safety benefits.
Price and Value
When I compared prices, the Cooper STT Pro 285/70R17 was competitively priced for a premium off-road tire. Given the performance, durability, and reliability, I felt it offered great value for the investment. Shopping around and looking for deals helped me get them at a reasonable cost.
Final Thoughts
If you’re looking for a tough, capable tire that can handle serious off-road conditions without compromising everyday drivability, the Cooper STT Pro 285/70R17 is an excellent choice. Make sure to verify your vehicle’s tire size compatibility and consider your driving needs. For me, these tires have been a game-changer, combining rugged performance with dependable on-road comfort.
