Understanding the 235/45R18 size

In the size code 235/45R18, 235 is the section width in millimetres (about 9.3"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 105.8 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 26.3".

The load index 94 means each tire supports up to 1,477 lbs — about 5,908 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 Bridgestone Weatherpeak is built for

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

Tread life and grip ratings

This tire carries a UTQG rating of 700 A A. The treadwear grade of 700 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 $172.49 per tire, a full set of four costs $689.96. That sits close to the average for the 155 tires we stock in this size. Backed by a 70,000-mile treadwear warranty, that works out to roughly $9.86 per 1,000 miles across the set.
