Understanding the 225/35ZR19 XL size

In the size code 225/35R19, 225 is the section width in millimetres (about 8.9"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 78.8 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 25.2".

The load index 88 means each tire supports up to 1,235 lbs — about 4,940 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 320 AA A. The treadwear grade of 320 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 $245.52 per tire, a full set of four costs $982.08. That is about 20% above the average of the 30 tires we stock in this size, reflecting its position in the range.
