Cooper Discoverer A/T3
Best all-terrain truck/SUV tire
The Cooper Discoverer A/T3 handles on-road driving better than many other all-terrain tires, and demanding off-road experts say it's plenty capable in deep mud, sand and loose dirt, too. Its 55,000-mile tread warranty is noteworthy, because many all-terrain tires carry no tread warranty. Although it plows through snow, the Discoverer A/T3 gets only a mediocre grip on ice, a shortcoming of most all-terrain tires, reviews say. If you don't venture off-road, experts say a regular all-season tire like the Michelin LTX M/S2 (*Est. $225) will deliver better dry-road handling, with better ice traction, a quieter ride, less rolling resistance for better gas mileage and longer tread life. The Cooper Discoverer A/T3 isn't designed for extreme mud bogging and rock crawling; for that, you'll need a specialized mud tire like the Goodyear Wrangler MT/R with Kevlar (*Est. $210).
