In the size code 245/40R18, 245 is the section width in millimetres (about 9.6"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 98 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.7".

The load index 97 means each tire supports up to 1,609 lbs — about 6,436 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).
