Understanding the 225/45R18 size

In the size code 225/45R18, 225 is the section width in millimetres (about 8.9"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 101.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 26".

The load index 91 means each tire supports up to 1,356 lbs — about 5,424 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 Winter Sottozero 3 is built for

The Pirelli Winter Sottozero 3 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, CAR, Performance, HP.

At $180.14 per tire, a full set of four costs $720.56. That is about 12% above the average of the 170 tires we stock in this size, reflecting its position in the range.
