The original tire specification for the BMW 3 Series is 225/45-R17. Below are the relevant details: 1. The main tire brands for the BMW 3 Series include Michelin PS3, Pirelli P7, Bridgestone Potenza, and Turanza, among others; 2. Important usage notes for BMW 3 Series tires: tread depth should not be less than 3 mm. When the tread depth is below 3 mm, there is a significant risk of hydroplaning when driving at high speeds in shallow water. Winter tires with a tread depth of less than 4 mm are clearly no longer suitable for winter driving. For safety reasons, new tires should be installed; 3.

They are typically installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
