Understanding the 235/40R18 size

In the size code 235/40R18, 235 is the section width in millimetres (about 9.3"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 94 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.4".

The load index 91 means each tire supports up to 1,356 lbs — about 5,424 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 560 A A. The treadwear grade of 560 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 $183.74 per tire, a full set of four costs $734.96. That is about 15% above the average of the 101 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 $14.70 per 1,000 miles across the set.
