My Buying Guides on Cooper Stt Pro 37X12 50R17
When I decided to upgrade my tires, the Cooper STT Pro 37X12.50R17 caught my attention. Here’s my personal guide to help you understand why this tire might be the right choice for you, based on my experience and research.
Understanding the Tire Size: 37X12.50R17
The numbers in the tire size can be confusing at first, but here’s what they mean to me:
- 37: This is the overall diameter of the tire in inches. A 37-inch tire gives you a taller profile, which is great for off-roading and provides better ground clearance.
- 12.50: This is the width of the tire in inches. A wider tire improves traction, especially in mud, sand, or snow.
- R17: This indicates that the tire fits a 17-inch wheel rim. Make sure your vehicle’s wheels are compatible with this size.
Why I Chose Cooper STT Pro
The Cooper STT Pro is known for its aggressive tread design and strong sidewalls. From my experience:
- It offers excellent off-road performance without sacrificing on-road comfort.
- The tread design helps with mud, rocks, and loose terrain, which was important since I love off-roading on weekends.
- The tire’s durability impressed me; it resists cuts and punctures better than many others I looked at.
Performance in Different Conditions
One thing I appreciated about the STT Pro is its versatility:
- Mud and Snow: The deep, aggressive tread blocks and self-cleaning design helped me maintain grip in muddy trails and snowy roads.
- On-Road Handling: Despite being a mud-terrain tire, it handled highway driving smoothly with minimal noise compared to other aggressive tires I tested.
- Wet Traction: The tire’s siping and tread pattern gave me confidence during rainy drives.
Load and Speed Ratings
It’s important to check the load and speed ratings before buying. For the 37X12.50R17 STT Pro, Cooper offers strong ratings suitable for heavy trucks and SUVs. This gave me peace of mind knowing the tire can handle my vehicle’s weight and typical driving speeds safely.
Installation and Fitment Tips
Since 37-inch tires are quite large, I had to make sure my vehicle had enough clearance to avoid rubbing. I recommend:
- Checking your suspension and fender space.
- Considering a lift kit if needed.
- Consulting with a tire professional to ensure proper fitment.
Also, balance and alignment after installation are crucial for longevity and ride comfort.
Price vs. Value
The Cooper STT Pro isn’t the cheapest tire out there, but I found the investment worth it. The combination of durability, off-road capability, and on-road comfort made it a good value for me. Keep an eye out for deals or package offers to save some money.
Final Thoughts
If you’re like me and want a tire that excels off-road but still performs well on highways, the Cooper STT Pro 37X12.50R17 is a solid choice. Just make sure your vehicle can accommodate the size, and be prepared for the slightly higher price point. Overall, it’s a tire I’m happy with and would recommend to fellow off-road enthusiasts.
I hope my guide helps you make an informed decision!
