Understanding the P265/65R18 size

In the size code 265/65R18, 265 is the section width in millimetres (about 10.4"). 65 is the aspect ratio — the sidewall height is 65% of the width, or roughly 172.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 31.6".

The load index 112 means each tire supports up to 2,469 lbs — about 9,876 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 600 A B. The treadwear grade of 600 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 $131.99 per tire, a full set of four costs $527.96. That is about 31% below the average price of the 106 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $8.80 per 1,000 miles across the set.
