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. Fitment category: Passenger Car, CAR, Performance, HP.
