My Buying Guides on 35X12 50X20 Cooper Stt Pro
When I first started looking for tires that could handle tough off-road conditions without compromising on-road performance, the 35X12.50X20 Cooper STT Pro quickly caught my attention. After researching and trying them out, here’s my personal guide to help you decide if these tires are the right fit for your vehicle and needs.
Understanding the Size: 35X12.50X20
The size 35X12.50X20 can seem confusing at first, but here’s what it means from my experience:
- 35: This is the tire’s overall diameter in inches. A 35-inch tire is quite large, providing great ground clearance and an aggressive look.
- 12.50: This number refers to the tire width in inches. At 12.5 inches wide, these tires offer a wide footprint for better traction.
- 20: This is the diameter of the wheel (rim) the tire fits, measured in inches. A 20-inch rim is common for trucks and SUVs.
Knowing these numbers helped me ensure the tire would fit my truck without any rubbing issues.
Why I Chose Cooper STT Pro
The Cooper STT Pro is well-known for its rugged durability and off-road capabilities. Here’s what stood out to me:
- Aggressive Tread Design: The deep, open tread blocks provide excellent traction in mud, snow, and rocky terrain.
- Durability: The tire’s reinforced sidewalls resist punctures and cuts, which gave me confidence on rough trails.
- Balanced On-Road Performance: Despite being an aggressive mud-terrain tire, the STT Pro offers reasonable noise levels and handling on highways.
Key Features I Looked For
When shopping for tires like the 35X12.50X20 Cooper STT Pro, I made sure to prioritize:
- Traction: The tire needs to perform well in a variety of conditions — mud, snow, sand, and rocky surfaces.
- Load Capacity: Since my vehicle carries heavy loads, I checked the tire’s load rating to ensure it could handle the weight safely.
- Durability and Construction: Tires with reinforced sidewalls and quality rubber compounds last longer and resist damage.
- Appearance: For me, the aggressive tread and sidewall design also add to my truck’s overall look.
Things to Consider Before Buying
Before making the purchase, I took these points into account to avoid surprises:
- Vehicle Compatibility: Make sure your truck or SUV can accommodate 35-inch tires without modifications.
- Fuel Efficiency: Larger tires can impact gas mileage; I was prepared for a slight decrease.
- Speedometer Calibration: Bigger tires can affect speedometer accuracy, so recalibration might be necessary.
- Noise Levels: While the STT Pro is quieter than some mud-terrain tires, expect more road noise than standard all-terrain tires.
Installation and Maintenance Tips from My Experience
Once I got my Cooper STT Pro tires, here’s how I made sure they performed at their best:
- Professional Mounting: I had the tires mounted and balanced by a professional to avoid vibrations.
- Regular Rotation: Rotating every 5,000 to 7,000 miles helped me maintain even wear.
- Proper Inflation: Keeping the tires inflated to the manufacturer’s recommended pressure maximizes lifespan and performance.
- Inspection: I routinely checked for cuts, punctures, or uneven wear, especially after off-road trips.
Final Thoughts
If you’re looking for a durable, aggressive tire that can handle tough off-road conditions and still provide decent on-road comfort, the 35X12.50X20 Cooper STT Pro is an excellent choice based on my experience. Just make sure your vehicle can support the size and that you’re okay with the trade-offs in fuel economy and noise. With proper care, these tires have the potential to enhance your off-road adventures and give your truck a commanding presence on the road.
