Understanding the HL285/40R23 XL size

In the size code 285/40R23, 285 is the section width in millimetres (about 11.2"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 114 mm. R23 means radial construction on a 23-inch wheel, giving an approximate overall diameter of 32".

The load index 115 means each tire supports up to 2,679 lbs — about 10,716 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 Primacy A/S is built for

The Michelin Primacy 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, UHP.

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 $350.99 per tire, a full set of four costs $1403.96. That is about 22% below the average price of the 12 tires we stock in this size. Backed by a 45,000-mile treadwear warranty, that works out to roughly $31.20 per 1,000 miles across the set.
