Understanding the 305/40R23 XL size

In the size code 305/40R23, 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. R23 means radial construction on a 23-inch wheel, giving an approximate overall diameter of 32.6".

The load index 115 means each tire supports up to 2,679 lbs — about 10,716 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 $221.25 per tire, a full set of four costs $885.00. That sits close to the average for the 2 tires we stock in this size.
