Understanding the 305/30ZR21 XL size

In the size code 305/30R21, 305 is the section width in millimetres (about 12"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 91.5 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 28.2".

The load index 104 means each tire supports up to 1,984 lbs — about 7,936 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 340 AA 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 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).

Price and value

At $324.74 per tire, a full set of four costs $1298.96. That is about 19% below the average price of the 21 tires we stock in this size. Backed by a 30,000-mile treadwear warranty, that works out to roughly $43.30 per 1,000 miles across the set.
