Understanding the 275/45R20 size

In the size code 275/45R20, 275 is the section width in millimetres (about 10.8"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 123.8 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 29.7".

The load index 110 means each tire supports up to 2,337 lbs — about 9,348 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 All Season is built for

The Firestone All Season is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries an M+S (mud and snow) marking for light winter service. Fitment category: Passenger Car, SUV/CUV, Performance, Touring.

Tread life and grip ratings

This tire carries a UTQG rating of 560 A B. 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 B reflects heat resistance at sustained speed (A is highest).

Price and value

At $191.99 per tire, a full set of four costs $767.96. That is about 19% below the average price of the 93 tires we stock in this size. Backed by a 55,000-mile treadwear warranty, that works out to roughly $13.96 per 1,000 miles across the set.
