The load index 107 means each tire supports up to 2,149 lbs — about 8,596 lbs across a full set of four. The speed symbol Y certifies the tire to 186 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

Tread life and grip ratings

This tire carries a UTQG rating of 300 AA A. The treadwear grade of 300 is a relative durability score — a grade of 200 is expected to last roughly twice as long as a grade of 100 under the same controlled test. Traction grade AA measures straight-line wet stopping grip (AA is highest, then A, B and C). Temperature grade A reflects heat resistance at sustained speed (A is highest).

At $419.24 per tire, a full set of four costs $1676.96. That sits close to the average for the 21 tires we stock in this size. Backed by a 30,000-mile treadwear warranty, that works out to roughly $55.90 per 1,000 miles across the set.
