Buying Guide for Cooper Discoverer Stronghold AT 275/60R20

Understanding the Tire Size and Specifications

When I first looked at the Cooper Discoverer Stronghold AT in the 275/60R20 size, I paid close attention to what those numbers meant. The 275 indicates the tire’s width in millimeters, while 60 is the aspect ratio, meaning the sidewall height is 60% of the width. The R stands for radial construction, and 20 is the wheel diameter in inches. Knowing this helped me ensure the tire would fit my vehicle properly and match my driving needs.

I made sure the load index and speed rating aligned with my vehicle’s specifications to maintain safety and performance.

The Discoverer Stronghold AT generally offers a quieter ride compared to more aggressive off-road tires, which suited my preference for highway driving.

Budget and Longevity Considerations

Lastly, I balanced cost against expected tire life. While all-terrain tires can be pricier than standard highway tires, I considered the investment worthwhile for the versatility and durability. I also factored in warranty coverage and tread life estimates to ensure long-term value.
