Understanding the 225/70R15 size

In the size code 225/70R15, 225 is the section width in millimetres (about 8.9"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 157.5 mm. R15 means radial construction on a 15-inch wheel, giving an approximate overall diameter of 27.4".

The load index 100 means each tire supports up to 1,764 lbs — about 7,056 lbs across a full set of four. The speed symbol S certifies the tire to 112 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 640 A A. The treadwear grade of 640 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 $97.34 per tire, a full set of four costs $389.36. That is about 14% below the average price of the 21 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $5.99 per 1,000 miles across the set.
