Understanding the 255/40R18 size

In the size code 255/40R18, 255 is the section width in millimetres (about 10"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 102 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 26".

The load index 95 means each tire supports up to 1,521 lbs — about 6,084 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.

Tread life and grip ratings

This tire carries a UTQG rating of 260 AA A. The treadwear grade of 260 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 AA 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 $279.38 per tire, a full set of four costs $1117.52. That is about 43% above the average of the 71 tires we stock in this size, reflecting its position in the range.
