Understanding the 245/40R18 size

In the size code 245/40R18, 245 is the section width in millimetres (about 9.6"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 98 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.7".

The load index 93 means each tire supports up to 1,433 lbs — about 5,732 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 800 A A. The treadwear grade of 800 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 $211.49 per tire, a full set of four costs $845.96. That is about 24% above the average of the 127 tires we stock in this size, reflecting its position in the range. Backed by a 80,000-mile treadwear warranty, that works out to roughly $10.57 per 1,000 miles across the set.
