Understanding the 355/25ZR21 XL size

In the size code 355/25R21, 355 is the section width in millimetres (about 14"). 25 is the aspect ratio — the sidewall height is 25% of the width, or roughly 88.8 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 28".

The load index 107 means each tire supports up to 2,149 lbs — about 8,596 lbs across a full set of four. The speed symbol Y certifies the tire to 186 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 4S is built for

The Michelin Pilot Sport 4S is a summer tire, tuned for maximum dry and wet grip in warm conditions; it is not intended for near-freezing temperatures. Fitment category: Passenger Car, CAR, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 300 AA A. The treadwear grade of 300 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 $1009.49 per tire, a full set of four costs $4037.96. That sits close to the average for the 6 tires we stock in this size. Backed by a 30,000-mile treadwear warranty, that works out to roughly $134.60 per 1,000 miles across the set.
