Understanding the 215/40R18 size

In the size code 215/40R18, 215 is the section width in millimetres (about 8.5"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 86 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 24.8".

The load index 85 means each tire supports up to 1,135 lbs — about 4,540 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. Fitment category: Passenger Car, CAR, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 320 AA A. The treadwear grade of 320 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 $224.24 per tire, a full set of four costs $896.96. That is about 47% above the average of the 32 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 $44.85 per 1,000 miles across the set.
