Understanding the 235/40R19 XL size

In the size code 235/40R19, 235 is the section width in millimetres (about 9.3"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 94 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 26.4".

The load index 96 means each tire supports up to 1,565 lbs — about 6,260 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 500 AA A. The treadwear grade of 500 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).

At $157.49 per tire, a full set of four costs $629.96. That is about 18% below the average price of the 120 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $12.60 per 1,000 miles across the set.
