Understanding the 235/55R18 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 100 means each tire supports up to 1,764 lbs — about 7,056 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.

Tread life and grip ratings

This tire carries a UTQG rating of 600 A A. 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 A reflects heat resistance at sustained speed (A is highest).

Price and value

At $188.99 per tire, a full set of four costs $755.96. That is about 19% above the average of the 147 tires we stock in this size, reflecting its position in the range. Backed by a 50,000-mile treadwear warranty, that works out to roughly $15.12 per 1,000 miles across the set.
