Understanding the HL245/35R21 XL size

In the size code 245/35R21, 245 is the section width in millimetres (about 9.6"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 85.8 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 27.8".

The load index 99 means each tire supports up to 1,709 lbs — about 6,836 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 280 AA A. The treadwear grade of 280 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 $350.40 per tire, a full set of four costs $1401.60. That is about 18% above the average of the 44 tires we stock in this size, reflecting its position in the range.
