What tires are used on the BMW 3 Series GT?
2 Answers
The BMW 3 Series GT uses Pirelli's CINTURATO P7 series tires, with front tire size being 225/50R18 and rear tire size being 255/45R18. These tires focus on environmental protection and fuel efficiency, featuring run-flat technology. GT stands for Grand Touring, which means large touring car in Chinese. The BMW 3 Series GT is positioned as a mid-size car with a hatchback body style. Its dimensions are 4824mm in length, 1828mm in width, 1518mm in height, with a wheelbase of 2920mm. For suspension, it uses MacPherson strut independent suspension at the front and multi-link independent suspension at the rear.
As a 3 Series GT owner, I've gained some insights after recently changing tires. The car originally comes with common sizes like 225/50 R18 Michelin Primacy 3 or Pirelli P7, which offer a good balance between handling and quietness. If you frequently drive on highways, Michelin PS4 performance tires provide better stability, with particularly noticeable wet grip. But remember to maintain tire pressure at 2.3-2.5 bar, and ensure the mechanic performs wheel balancing during tire changes, otherwise the steering wheel may vibrate at high speeds. Regular tread depth checks are crucial - replace them when below 3mm. Also avoid tires older than 3 years as rubber aging affects performance.
