Understanding the 225/45R17 size

In the size code 225/45R17, 225 is the section width in millimetres (about 8.9"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 101.3 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25".

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 H certifies the tire to 130 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 700 A A. The treadwear grade of 700 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 $118.49 per tire, a full set of four costs $473.96. That is about 12% below the average price of the 163 tires we stock in this size. Backed by a 75,000-mile treadwear warranty, that works out to roughly $6.32 per 1,000 miles across the set.
