Understanding the 255/50R20 XL size

In the size code 255/50R20, 255 is the section width in millimetres (about 10"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 127.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 30".

The load index 109 means each tire supports up to 2,271 lbs — about 9,084 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 Nokian Nokian ONE is built for

The Nokian Nokian ONE 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. Fitment category: Passenger Car.

Tread life and grip ratings

This tire carries a UTQG rating of 720 A A. The treadwear grade of 720 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).

At $190.79 per tire, a full set of four costs $763.16. That sits close to the average for the 121 tires we stock in this size. Backed by a 80,000-mile treadwear warranty, that works out to roughly $9.54 per 1,000 miles across the set.
