Extreme performance tires are as close to racing tires as one can get for a passenger vehicle. They are designed for dry surfaces and competition-level performance. These are not everyday tires. Go for these tires when it's time to take the BMW for a run on the track.
Ultra-high and high-performance tires favor predictable handling and improved ride quality. Generally, the UHP tires will carry the "V" speed rating. Refer to the chart above and discuss your driving needs with a tire professional.
Touring tires focus on fuel efficiency and ride quality while stepping down a notch in handling and performance. Touring tires are less expensive than performance tires and are suitable for daily drivers.
On the low end, passenger tires are generally lower in price and performance, though winter models can be an exception. Remember you get what you pay for: low priced tires won’t last as long or provide the best traction or safety.
Winter tires offer the best traction, handling and braking in cold weather. Winter passenger tires can provide the best performance in snow and ice; however, these tires will wear out quicker if driven when temperatures are above 45 degrees.
Run Flat Tires
Run Flat tires are designed to resist the effects of deflation when punctured and to enable the vehicle to continue to be driven at reduced speeds (under 55 mph) and for limited distances (up to 10 mi). Many new cars do not have spare tires and are instead using run flat tires. These tires are more expensive and provide a slightly rougher ride.
