1. What is the tire brand/style on your oem 19s? Michelin Diamaris summer only in winter 18" Pirelli Scorpions
2. What is your Front and Rear tire pressure? 32 all around
3. How is the ride? Stiff - my wintersw give a softer ride - but I ordered the sport pack because with my driving style it is safer
4. Is it durable and what is your driving habit? have not had to replace - but I put more summer miles on my Z4. Driving habits - mix of commute and long highway - opportunity to enjoy the car it is a great ride at 75-90 mph over that I would like to keep my licence - 130 plus is reserved for when I have a police officer riding shotgun. The Diamaris are very good, in really tight cornering the Z4 (3.0 sport pack) only beats the X5 by 5 mph.
5. Where did you get the tires? n/a
