This tire has a Uniform Tire Quality Grading (UTQG) of 640 A B.
The UTQG is made up of 3 components, temperature, traction, and treadwear.
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test track in San Angelo, TX. In this case, a tire graded 640 would wear 6.4 tires as long on the government test course under specified test conditions as one graded 100. It is wrong to link treadwear grades with your projected tire mileage. The relative performance of tires depends upon the actual conditions of their use and may vary due to driving habits, service practices, differences in road characteristics and climate.
