GMC Terrain: All-Season Tires, Winter Tires and Summer Tires / All-Season Tires

GMC Terrain 2018-2023 Owners Manual / Vehicle Care / Wheels and Tires / All-Season Tires, Winter Tires and Summer Tires / All-Season Tires

This vehicle may come with all-season tires. These tires are designed to provide good overall

performance on most road surfaces and weather conditions. Original equipment tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.”

Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires.
