1. BMW AG test results. BMW urges to obey all posted speed laws and always wear safety belts.
2. Driving over rough or damaged road surfaces, as well as debris, curbs and other obstacles, can cause serious damage to wheels,tires and suspension parts. This is more likely to occur with low-profile tires, which provide less cushioning between the wheel and the road. Be careful to avoid road hazards and reduce your speed, especially if your vehicle is equipped with low-profile tires. Performance tires are not recommended for driving in ice and snow conditions. Please note: M3 models are not equipped with a spare tire and wheel. They include M Mobility System, which offers lifetime BMW Roadside Assistance for tire assistance.
3. EPA-estimated figures are for comparison purposes only. Your actual mileage will vary, depending on speed, driving habits, trip length and driving conditions; actual mileage may be lower.
