Understanding the 235/40R18 XL size

In the size code 235/40R18, 235 is the section width in millimetres (about 9.3"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 94 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.4".

The load index 95 means each tire supports up to 1,521 lbs — about 6,084 lbs across a full set of four. The speed symbol H certifies the tire to 130 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 Primacy Tour A/S is built for

The Michelin Primacy Tour A/S is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries an M+S (mud and snow) marking for light winter service. Fitment category: Passenger Car, Performance, HP.

Tread life and grip ratings

This tire carries a UTQG rating of 540 A A. The treadwear grade of 540 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 $167.99 per tire, a full set of four costs $671.96. That sits close to the average for the 101 tires we stock in this size. Backed by a 55,000-mile treadwear warranty, that works out to roughly $12.22 per 1,000 miles across the set.
