Understanding the 185/55R15 size

In the size code 185/55R15, 185 is the section width in millimetres (about 7.3"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 101.8 mm. R15 means radial construction on a 15-inch wheel, giving an approximate overall diameter of 23".

The load index 82 means each tire supports up to 1,047 lbs — about 4,188 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 660 A A. The treadwear grade of 660 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 $62.99 per tire, a full set of four costs $251.96. That is about 33% below the average price of the 16 tires we stock in this size. Backed by a 75,000-mile treadwear warranty, that works out to roughly $3.36 per 1,000 miles across the set.
