My Buying Guides on Cooper Stt Pro 37X12 50R17
When I decided to upgrade my vehicle’s tires, I chose the Cooper STT Pro 37X12.50R17, and I want to share my experience and what I learned along the way. If you’re considering these tires, here’s everything you need to know from my perspective.
Understanding the Tire Size and What It Means
The size 37X12.50R17 might look confusing at first, but here’s how I break it down:
- 37 means the overall diameter of the tire is 37 inches, which is quite large and perfect for off-road adventures.
- 12.50 is the tire width in inches, giving you a wide footprint for better traction.
- R17 indicates the tire fits 17-inch rims, which are common on many trucks and SUVs.
Knowing this helped me ensure the tires would fit my vehicle properly without needing extensive modifications.
Why I Chose the Cooper STT Pro
I picked the Cooper STT Pro because it’s designed specifically for aggressive off-road use but still performs well on highways. The deep, aggressive tread pattern provides excellent grip in mud, snow, and rocky terrain, which is exactly what I needed for my weekend trails. Plus, Cooper’s reputation for durability gave me confidence that these tires would last.
Performance and Handling
After installing the 37X12.50R17 STT Pros, I noticed a significant improvement in traction and handling on rough terrain. The tire’s sidewall design also adds extra protection against punctures, which gave me peace of mind during off-road trips. On the road, they’re a bit louder than standard tires, but that’s expected with aggressive tread patterns — it’s a trade-off I was willing to make.
Load Capacity and Durability
These tires have a high load rating, which is crucial if you carry heavy gear or tow trailers like I do. I appreciated the reinforced sidewalls and tough rubber compound, which helped resist cuts and abrasions. This durability means fewer replacements over time, saving me money in the long run.
Things to Consider Before Buying
- Vehicle Compatibility: Make sure your truck or SUV can accommodate a 37-inch tire without rubbing or suspension issues. I had to do a slight lift to fit mine perfectly.
- Fuel Economy: Larger, heavier tires can reduce fuel efficiency. I noticed a slight drop but found it acceptable for the off-road benefits.
- Noise Level: Expect more road noise compared to highway tires. If you prioritize a quiet ride, this might not be ideal.
- Cost: These are premium tires, so they’re an investment. But in my experience, the performance and durability justify the price.
Final Thoughts
Buying the Cooper STT Pro 37X12.50R17 was one of the best decisions I made for my off-road setup. They offer a perfect balance of toughness, traction, and road performance for anyone serious about off-roading but who still drives on pavement regularly. If you’re like me and want reliable, aggressive tires that can handle whatever terrain you throw at them, these are definitely worth considering.
