Toyo Open Country A/T III EV

In the US, the Toyo Open Country AT III EV carries a UTQG treadwear grade of 600, with traction A and temperature A-B. UTQG treadwear is relative: a tyre graded 400 lasted four times as long as the reference tyre, graded 100, on the government test course. Toyo backs it with a limited treadwear warranty of 50,000 to 65,000 miles, depending on size and speed rating. New tread depth is 16.4-16.8/32" (13.0-13.3 mm), depending on size.
