Understanding the 205/40ZR18 XL size

In the size code 205/40R18, 205 is the section width in millimetres (about 8.1"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 82 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 24.5".

The load index 86 means each tire supports up to 1,168 lbs — about 4,672 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 $191.99 per tire, a full set of four costs $767.96. That sits close to the average for the 15 tires we stock in this size. Backed by a 20,000-mile treadwear warranty, that works out to roughly $38.40 per 1,000 miles across the set.
