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 Pirelli Scorpion Winter is built for

The Pirelli Scorpion Winter is a winter tire, using a cold-weather compound that stays pliable below 45°F (7°C) where all-season rubber hardens and loses grip. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. Run-flat construction lets you keep driving a limited distance at reduced speed after a loss of pressure. Fitment category: Passenger Car, SUV/CUV.

Price and value

At $202.62 per tire, a full set of four costs $810.48. That sits close to the average for the 83 tires we stock in this size.
