In the size code 235/30R22, 235 is the section width in millimetres (about 9.3"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 70.5 mm. R22 means radial construction on a 22-inch wheel, giving an approximate overall diameter of 27.6".
The load index 90 means each tire supports up to 1,323 lbs — about 5,292 lbs across a full set of four. The speed symbol Y certifies the tire to 186 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 300 AA A. The treadwear grade of 300 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 AA 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).

At $169.50 per tire, a full set of four costs $678.00. That is about 10% below the average price of the 2 tires we stock in this size. Backed by a 25,000-mile treadwear warranty, that works out to roughly $27.12 per 1,000 miles across the set.
