In the size code 245/40R18, 245 is the section width in millimetres (about 9.6"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 98 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 25.7".
The load index 97 means each tire supports up to 1,609 lbs — about 6,436 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 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.
Price and value
At $172.39 per tire, a full set of four costs $689.56. That sits close to the average for the 127 tires we stock in this size.
