Understanding the 255/55R19 XL size

In the size code 255/55R19, 255 is the section width in millimetres (about 10"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 140.3 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 30".

The load index 111 means each tire supports up to 2,403 lbs — about 9,612 lbs across a full set of four. The speed symbol V certifies the tire to 149 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

What the Toyo Proxes ST III is built for

The Toyo Proxes ST III is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries an M+S (mud and snow) marking for light winter service. It is classified for highway terrain(h/t) use.

Tread life and grip ratings

This tire carries a UTQG rating of 500 A 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 A 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 $212.76 per tire, a full set of four costs $851.04. That sits close to the average for the 58 tires we stock in this size. Backed by a 40,000-mile treadwear warranty, that works out to roughly $21.28 per 1,000 miles across the set.
