The 55 is the aspect ratio, meaning the sidewall height is 55% of the tire’s width. The “R” stands for radial construction, which is standard for modern tires. Finally, 20 is the wheel diameter in inches. This size is common for many trucks and SUVs, offering a good balance between on-road comfort and off-road capability.
Why I Chose Cooper Discoverer AT
I wanted a tire that performs well both on highways and off-road trails. The Cooper Discoverer AT is known for its all-terrain versatility. It features an aggressive tread pattern that provides excellent grip in mud, gravel, and snow but still offers a relatively quiet ride on pavement. The durability and tread life also impressed me, making it a cost-effective choice in the long run.
Performance Features That Matter
- Traction: The Discoverer AT uses multi-angle tread blocks and siping to enhance traction in wet, dry, and snowy conditions. I felt confident driving through rain and light snow without worrying about slipping.
- Durability: The reinforced sidewalls helped protect against punctures and sidewall damage, which was important for my occasional off-road adventures.
- Comfort: Despite being an all-terrain tire, I found the ride smooth and noise levels acceptable for daily driving.
- Tread Life: Cooper claims a long tread life warranty, and based on my experience, the tires hold up well over tens of thousands of miles.
What to Consider Before Buying
Before you pull the trigger, here are a few things I recommend thinking about:
- Vehicle Compatibility: Make sure 275/55R20 is the recommended size for your vehicle. Using the wrong tire size can affect handling and safety.
- Driving Conditions: If you mostly drive on highways, you might want a tire with a quieter tread. But if you frequently go off-road or in varying weather, the Discoverer AT is a solid choice.
- Budget: These tires are moderately priced compared to premium brands. I found the value excellent given their performance.
- Installation and Balancing: Factor in installation costs, balancing, and alignment services to get the best performance and longevity.
