Understanding the 255/40R20 XL size

In the size code 255/40R20, 255 is the section width in millimetres (about 10"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 102 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 28".

The load index 101 means each tire supports up to 1,819 lbs — about 7,276 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 Michelin Pilot Sport A/S Plus is built for

The Michelin Pilot Sport A/S Plus is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. Fitment category: Passenger Car, CAR, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 500 AA 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 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 $365.24 per tire, a full set of four costs $1460.96. That is about 33% above the average of the 93 tires we stock in this size, reflecting its position in the range. Backed by a 45,000-mile treadwear warranty, that works out to roughly $32.47 per 1,000 miles across the set.
