Understanding the 245/45R20 XL size

In the size code 245/45R20, 245 is the section width in millimetres (about 9.6"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 110.3 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 28.7".

The load index 103 means each tire supports up to 1,929 lbs — about 7,716 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.

At $355.45 per tire, a full set of four costs $1421.80. That is about 65% above the average of the 129 tires we stock in this size, reflecting its position in the range.
