What the Cooper Evolution Winter is built for
The Cooper Evolution 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. Fitment category: Passenger Car.
