The load index 103 means each tire supports up to 1,929 lbs — about 7,716 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 260 AA A. The treadwear grade of 260 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 $362.34 per tire, a full set of four costs $1449.36. That is about 31% above the average of the 3 tires we stock in this size, reflecting its position in the range.
