Understanding the 235/55R18 XL size

In the size code 235/55R18, 235 is the section width in millimetres (about 9.3"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 129.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 28.2".

The load index 104 means each tire supports up to 1,984 lbs — about 7,936 lbs across a full set of four. The speed symbol V certifies the tire to 149 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 Enduramax is built for

The Cooper Discoverer Enduramax 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. Fitment category: Passenger Car, SUV/CUV.

Tread life and grip ratings

This tire carries a UTQG rating of 640 A A. The treadwear grade of 640 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 A reflects heat resistance at sustained speed (A is highest).

Price and value

At $158.24 per tire, a full set of four costs $632.96. That sits close to the average for the 147 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $10.55 per 1,000 miles across the set.
