My Buying Guides on Cooper Stt Pro 37X12.50R17
When I decided to upgrade my truck tires, the Cooper STT Pro 37X12.50R17 caught my attention immediately. After using them for a while, I wanted to share my experience and some key points to consider if you’re thinking about buying these tires.
Understanding the Size: 37X12.50R17
The size 37X12.50R17 means the tire diameter is 37 inches, the width is 12.5 inches, and it fits a 17-inch rim. This is a large, aggressive tire size, perfect for off-road enthusiasts like me who need extra ground clearance and traction. Make sure your vehicle can accommodate this size without rubbing or requiring modifications.
Performance on Different Terrains
One thing I loved about the STT Pro is its versatility. The aggressive tread pattern offers excellent grip in mud, dirt, rocks, and snow. On highways, the ride is surprisingly smooth for such a rugged tire, although you can expect a bit more road noise compared to standard all-season tires. If you frequently switch between off-road and on-road driving, these tires strike a good balance.
Durability and Build Quality
Cooper designed the STT Pro with a tough sidewall and puncture-resistant features. After months of off-roading and rough terrain, I noticed minimal wear and no sidewall damage. This tire feels built to last, which is crucial if you’re investing in larger, more expensive tires.
Load and Speed Ratings
These tires are rated to handle heavy loads, which is important for trucks carrying gear or towing. Before purchasing, I checked the specific load and speed ratings to ensure they match my vehicle’s requirements. Always verify these ratings to maintain safety and performance.
Fuel Efficiency Considerations
Because of their size and aggressive tread, the STT Pro can slightly reduce fuel efficiency compared to smaller or less aggressive tires. In my experience, the trade-off is worth it for the enhanced off-road capability, but it’s something to keep in mind if you’re conscious about gas mileage.
Installation and Fitment Tips
When I upgraded to 37X12.50R17 tires, I had to make sure my truck had proper lift and clearance. Sometimes, you might need additional modifications like trimming or suspension upgrades. I recommend consulting with a professional installer to avoid fitment issues.
Price vs. Value
These tires aren’t the cheapest on the market, but I found the price justified by their performance and durability. If you’re serious about off-roading or want a tire that can handle tough conditions without frequent replacements, the Cooper STT Pro is a solid investment.
Final Thoughts
If you want a tire that can handle extreme off-road conditions while still performing decently on the road, the Cooper STT Pro 37X12.50R17 is a great choice. Just make sure your vehicle can accommodate this size and be prepared for a slight impact on fuel economy. From my experience, these tires deliver excellent traction, toughness, and reliability.
