Understanding the 305/40R22 XL size

In the size code 305/40R22, 305 is the section width in millimetres (about 12"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 122 mm. R22 means radial construction on a 22-inch wheel, giving an approximate overall diameter of 31.6".

The load index 114 means each tire supports up to 2,601 lbs — about 10,404 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 460 A A. The treadwear grade of 460 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 $160.50 per tire, a full set of four costs $642.00. That is about 30% below the average price of the 13 tires we stock in this size.
