Open Country A/T III

Toyo Open Country A/T III: what the numbers tell you

The Open Country A/T III's UTQG treadwear rating of 580 puts it in the long-wear class. Its compound is engineered for life over outright grip, which is appropriate for an everyday touring tire. The 65,000-mile warranty is one of the most concrete data points for a tire. It is the manufacturer's own statement of compound durability under normal use. Warranty replacement is typically prorated, so it will not fully offset the cost of a new tire, but the warranty length is a reasonable expectation of useful tread life.

Cabin noise of 74 dB is on the louder end, a result of the tread pattern needed for the tire's grip class. Buyers prioritizing cabin quiet should compare against a touring tire in the same size. As a all-season tire built for the truck-suv segment, the Open Country A/T III is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.

All-terrain tire for trucks and SUVs. Severe-snow rated, 65k warranty.
