Understanding the 255/45R20 XL size

In the size code 255/45R20, 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. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 29".

The load index 105 means each tire supports up to 2,039 lbs — about 8,156 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 Hankook Weatherflex GT H755 is built for

The Hankook Weatherflex GT H755 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. Fitment category: Passenger Car, SUV/CUV, Performance, HP.

Tread life and grip ratings

This tire carries a UTQG rating of 720 A A. The treadwear grade of 720 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 $181.49 per tire, a full set of four costs $725.96. That is about 24% below the average price of the 157 tires we stock in this size. Backed by a 70,000-mile treadwear warranty, that works out to roughly $10.37 per 1,000 miles across the set.
