My Buying Guides on Cooper Stt Pro 37X12 50R17
When I decided to upgrade my truck’s tires, I came across the Cooper STT Pro 37X12.50R17. After some research and hands-on experience, I want to share my insights to help you decide if these tires are right for you.
Understanding the Size: 37X12.50R17
The size 37X12.50R17 breaks down into key details that matter. The “37” means the tire diameter is 37 inches, which gives a taller tire for better ground clearance. “12.50” is the tire width in inches, offering a wider footprint for improved traction. Finally, “R17” indicates the tire fits a 17-inch rim. I made sure my truck could handle this size before buying to avoid any fitment issues.
Performance on Different Terrains
One thing I appreciate about the Cooper STT Pro is its excellent off-road capability. The aggressive tread design with deep lugs helped me tackle mud, rocks, and loose dirt with confidence. On paved roads, these tires remain relatively quiet and stable, though they’re definitely more rugged than highway tires. If you spend a lot of time off-roading but still want reasonable on-road manners, these tires strike a nice balance.
Durability and Construction
From my experience, the STT Pro tires are built tough. They feature reinforced sidewalls that resist punctures and cuts, which gave me peace of mind on rough trails. The tire’s compound also holds up well against wear, so I expect them to last through many seasons. I always check for any signs of damage after my off-road trips, and these tires have performed reliably so far.
Load and Speed Ratings
Before buying, I checked the load and speed ratings to ensure the tires meet my truck’s requirements. The 37X12.50R17 Cooper STT Pro typically has a load range suitable for heavy trucks and SUVs, which is critical for carrying gear or towing. The speed rating is adequate for everyday driving speeds but remember these are mainly off-road tires, so they aren’t designed for high-speed performance.
Price and Value
I found the Cooper STT Pro 37X12.50R17 to be reasonably priced compared to other premium off-road tires in this size. Considering their durability, traction, and versatility, I feel they offer great value for anyone serious about off-road adventures without sacrificing too much on-road comfort.
Installation and Maintenance Tips
When installing these tires, I had them balanced and aligned professionally to maximize their lifespan and performance. Regularly rotating the tires every 5,000 to 7,000 miles helped me maintain even wear. Also, keeping an eye on tire pressure is crucial, especially when switching between highway driving and off-road conditions.
Final Thoughts
If you’re looking for a rugged, reliable tire that can handle tough off-road environments and still perform decently on the highway, the Cooper STT Pro 37X12.50R17 is worth considering. Just make sure your vehicle can accommodate the larger size and that you’re prepared for the slightly rougher ride compared to standard road tires. From my personal experience, these tires have enhanced my truck’s capability and confidence on all terrains.
