Understanding the 255/40R21 XL size

In the size code 255/45R21, 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. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 30".

The load index 102 means each tire supports up to 1,874 lbs — about 7,496 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 Pirelli Scorpion Zero All Season is built for

The Pirelli Scorpion Zero All Season 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, SUV/CUV.

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 $400.18 per tire, a full set of four costs $1600.72. That is about 12% above the average of the 12 tires we stock in this size, reflecting its position in the range.
