Michelin Pilot Alpin 5 245/55 R18 Subaru 2024 WRX GT 4,000 miles December 1, 2025
Been using them for 2 seasons now on a Subaru wrx. Slush category - 7 Snow they drive great! In slush theres a bit of understeer but controllable in a awd car with a bit of power. Ice, I've only driven on a iced over driveway and it faired pretty well. Updated: road ice, the tires will slip soo be careful.
