My Buying Guides on 35X12 50X20 Cooper Stt Pro
When I decided to invest in a new set of tires for my truck, I knew I wanted something that could handle tough terrains while providing excellent performance on the road. After much research, I stumbled upon the 35X12.50R20 Cooper STT Pro, and I couldn’t be happier with my choice. Here’s my buying guide based on my experience.
Understanding Tire Specifications
When I first looked at the 35X12.50R20 designation, I quickly realized what it meant. The “35” indicates the tire’s diameter in inches, while “12.50” refers to the width in inches. The “R20” signifies that it fits a 20-inch rim. This combination offers a great balance of height and width, giving my truck a commanding presence and enhancing its off-road capabilities.
Performance on Different Terrains
One of the main reasons I chose the Cooper STT Pro is its performance on a variety of terrains. I’ve taken these tires through mud, sand, and rocky paths, and I’ve been impressed with how they grip the ground. The aggressive tread design provides excellent traction, allowing me to tackle off-road challenges with confidence. I also appreciate that they perform well on highways, providing a smoother ride than I expected for an aggressive tire.
Durability and Longevity
Durability was a top priority for me, and the Cooper STT Pro did not disappoint. Constructed with a robust compound that resists cuts and punctures, I’ve driven over sharp rocks and debris without worrying about damage. After several months of use, the tread still looks great, which gives me confidence in their longevity. I’ve noticed less wear compared to other tires I’ve had in the past.
Noise Levels
I was concerned about the noise level since I often drive on highways. The Cooper STT Pro does have a more aggressive tread pattern, which can produce some road noise. However, it’s not as loud as I had anticipated. I find it tolerable, especially considering the tire’s off-road capabilities. If you’re looking for a quiet tire, this might not be your best option, but for me, the trade-off was worth it.
Price and Value
In my search for tires, price was always a consideration. The Cooper STT Pro falls in the mid to upper price range compared to other tires in its class. However, I believe the performance and durability justify the cost. I’ve found that investing in quality tires can save me money in the long run by reducing the frequency of replacements.
Installation and Maintenance
When it came time to install my Cooper STT Pro tires, I opted for a professional installation to ensure everything was done correctly. I recommend this to anyone who may not have experience with tire installation. As for maintenance, I regularly check the tire pressure and rotate them every 5,000 miles, which helps maintain even wear and prolong their life.
Final Thoughts
Overall, my experience with the 35X12.50R20 Cooper STT Pro has been fantastic. They offer a perfect blend of off-road performance, durability, and decent on-road comfort. If you’re in the market for versatile tires that can handle various conditions, I highly recommend giving these a try. My truck feels more capable than ever, and I’m excited for the adventures that lie ahead!
