Understanding the 255/45ZR18 size

In the size code 255/45R18, 255 is the section width in millimetres (about 10"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 114.8 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 27".

The load index 99 means each tire supports up to 1,709 lbs — about 6,836 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 Hankook Ventus S1 AS (H125) is built for

The Hankook Ventus S1 AS (H125) 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.

Tread life and grip ratings

This tire carries a UTQG rating of 560 AA A. The treadwear grade of 560 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 AA 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 $173.24 per tire, a full set of four costs $692.96. That sits close to the average for the 43 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $13.86 per 1,000 miles across the set.
