Understanding the 265/70R18 size

In the size code 265/70R18, 265 is the section width in millimetres (about 10.4"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 185.5 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 32.6".

The load index 116 means each tire supports up to 2,756 lbs — about 11,024 lbs across a full set of four. The speed symbol H certifies the tire to 130 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

What the Cooper Discoverer Road + Trail AT is built for

The Cooper Discoverer Road + Trail AT is an all-weather tire — a year-round option certified for severe snow service, so it can stay on the vehicle through winter. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. It is classified for all-terrain (a/t) use.

Tread life and grip ratings

This tire carries a UTQG rating of 620 A B. The treadwear grade of 620 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 $209.99 per tire, a full set of four costs $839.96. That sits close to the average for the 117 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $12.92 per 1,000 miles across the set.
