Understanding the 245/40R21 size

In the size code 245/40R21, 245 is the section width in millimetres (about 9.6"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 98 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 28.7".

The load index 96 means each tire supports up to 1,565 lbs — about 6,260 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 S 5 is built for

The Michelin Pilot Sport S 5 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, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 300 A 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 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 $536.99 per tire, a full set of four costs $2147.96. That is about 30% above the average of the 22 tires we stock in this size, reflecting its position in the range. Backed by a 30,000-mile treadwear warranty, that works out to roughly $71.60 per 1,000 miles across the set.
