Understanding the 215/35R18 XL size

In the size code 215/35R18, 215 is the section width in millimetres (about 8.5"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 75.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 23.9".

The load index 84 means each tire supports up to 1,102 lbs — about 4,408 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).

Price and value

At $119.25 per tire, a full set of four costs $477.00. That is about 23% below the average price of the 3 tires we stock in this size. Backed by a 25,000-mile treadwear warranty, that works out to roughly $19.08 per 1,000 miles across the set.
