Understanding the 255/45R19 size

In the size code 255/45R19, 255 is the section width in millimetres (about 10"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 114.8 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 28".

The load index 100 means each tire supports up to 1,764 lbs — about 7,056 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).

Price and value

At $195.75 per tire, a full set of four costs $783.00. That is about 14% below the average price of the 93 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $15.66 per 1,000 miles across the set.
