My Buying Guides on 35X12 50X20 Cooper STT Pro
When I was searching for the perfect tires for my truck, the 35X12.50X20 Cooper STT Pro caught my attention. If you’re considering these tires, here’s what I learned and what helped me make my decision.
Understanding the Size: 35X12.50X20
The numbers in 35X12.50X20 represent the tire’s dimensions:
- 35 inches: The overall diameter of the tire.
- 12.50 inches: The width of the tire.
- 20 inches: The diameter of the wheel rim it fits.
This size is ideal if you want a bold, aggressive look with better ground clearance. I found that these tires fit perfectly on my 20-inch wheels without any rubbing issues, which is important if you plan to lift your truck or do off-roading.
Why I Chose Cooper STT Pro
Cooper STT Pro tires are known for their durability and off-road performance. From my experience:
- Aggressive tread design: The deep, aggressive tread blocks provide excellent traction in mud, snow, and rocky terrain.
- Sidewall strength: The reinforced sidewalls helped protect against punctures and cuts when I was driving through rough trails.
- All-terrain versatility: Even though they’re tough off-road, they still offered a relatively smooth and quiet ride on highways, which I appreciated during my daily drives.
Performance Highlights
When I tested these tires, here’s what stood out:

- Self-cleaning: The tread design helped eject mud and stones, maintaining traction without manual cleaning.
What to Consider Before Buying
Before purchasing the 35X12.50X20 Cooper STT Pro, I kept these points in mind:
