Understanding the 265/60R18 size
In the size code 265/60R18, 265 is the section width in millimetres (about 10.4"). 60 is the aspect ratio — the sidewall height is 60% of the width, or roughly 159 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 30.5".
The load index 110 means each tire supports up to 2,337 lbs — about 9,348 lbs across a full set of four. The speed symbol T certifies the tire to 118 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 740 A B. The treadwear grade of 740 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 A measures straight-line wet stopping grip (AA is highest, then A, B and C). Temperature grade B reflects heat resistance at sustained speed (A is highest).
Price and value
At $158.99 per tire, a full set of four costs $635.96. That is about 12% below the average price of the 135 tires we stock in this size. Backed by a 75,000-mile treadwear warranty, that works out to roughly $8.48 per 1,000 miles across the set.
