Understanding the 205/55R16 size

In the size code 205/55R16, 205 is the section width in millimetres (about 8.1"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 112.8 mm. R16 means radial construction on a 16-inch wheel, giving an approximate overall diameter of 24.9".

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 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.

What the Firestone Affinity AS is built for

The Firestone Affinity AS is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. Fitment category: Passenger Car.

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 $98.24 per tire, a full set of four costs $392.96. That is about 12% below the average price of the 136 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $6.05 per 1,000 miles across the set.
