Understanding the 215/40R18 XL size

In the size code 215/40R18, 215 is the section width in millimetres (about 8.5"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 86 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 24.8".

The load index 89 means each tire supports up to 1,279 lbs — about 5,116 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.

What the Nokian Surpass AS01 is built for

The Nokian Surpass AS01 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, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 560 AA A. The treadwear grade of 560 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 $130.76 per tire, a full set of four costs $523.04. That is about 14% below the average price of the 32 tires we stock in this size. Backed by a 55,000-mile treadwear warranty, that works out to roughly $9.51 per 1,000 miles across the set.
