Understanding the 225/40R18 XL size

In the size code 225/40R18, 225 is the section width in millimetres (about 8.9"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 90 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.1".

The load index 92 means each tire supports up to 1,389 lbs — about 5,556 lbs across a full set of four. The speed symbol V certifies the tire to 149 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 GT Radial Maxclimate is built for

It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test.

Tread life and grip ratings

This tire carries a UTQG rating of 600 A A. The treadwear grade of 600 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 $113.24 per tire, a full set of four costs $452.96. That is about 25% below the average price of the 144 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $7.55 per 1,000 miles across the set.
