Understanding the 255/70R18 size

In the size code 255/70R18, 255 is the section width in millimetres (about 10"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 178.5 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 32.1".

The load index 113 means each tire supports up to 2,535 lbs — about 10,140 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 500 A B. The treadwear grade of 500 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 $113.25 per tire, a full set of four costs $453.00. That is about 39% below the average price of the 66 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $9.06 per 1,000 miles across the set.
