Understanding the 225/50R17 size

In the size code 225/50R17, 225 is the section width in millimetres (about 8.9"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 112.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25.9".

The load index 94 means each tire supports up to 1,477 lbs — about 5,908 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 340 A A. The treadwear grade of 340 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 $137.24 per tire, a full set of four costs $548.96. That sits close to the average for the 146 tires we stock in this size.
