Understanding the 245/45ZR19 XL size

In the size code 245/45R19, 245 is the section width in millimetres (about 9.6"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 110.3 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 27.7".

The load index 102 means each tire supports up to 1,874 lbs — about 7,496 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 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 $199.50 per tire, a full set of four costs $798.00. That sits close to the average for the 142 tires we stock in this size.
