Understanding the 315/35ZR20 XL size

In the size code 315/35R20, 315 is the section width in millimetres (about 12.4"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 110.3 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 28.7".

The load index 110 means each tire supports up to 2,337 lbs — about 9,348 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 4 is built for

The Michelin Pilot Sport 4 is a summer tire, tuned for maximum dry and wet grip in warm conditions; it is not intended for near-freezing temperatures. 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 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 $509.24 per tire, a full set of four costs $2036.96. That is about 48% above the average of the 54 tires we stock in this size, reflecting its position in the range. Backed by a 20,000-mile treadwear warranty, that works out to roughly $101.85 per 1,000 miles across the set.
