Understanding the 255/55R18 XL size

In the size code 255/55R18, 255 is the section width in millimetres (about 10"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 140.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 29".

The load index 109 means each tire supports up to 2,271 lbs — about 9,084 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 BFGoodrich Trail-Terrain T/A is built for

The BFGoodrich Trail-Terrain T/A is an all-weather tire — a year-round option certified for severe snow service, so it can stay on the vehicle through winter. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. It is classified for all-terrain (a/t) use.

Tread life and grip ratings

This tire carries a UTQG rating of 660 B A. The treadwear grade of 660 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 B 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 $208.49 per tire, a full set of four costs $833.96. That is about 10% above the average of the 83 tires we stock in this size, reflecting its position in the range. Backed by a 65,000-mile treadwear warranty, that works out to roughly $12.83 per 1,000 miles across the set.
