I have recently gone from 18" Re050 to 19" MPS2, the ride is better despite smaller sidewalls there is a load more communication. a friend of mine had vreds and then kumho on his E39 M5 got 6k and 4k respectively, i got 11k out of Bridgestones and still had 3.5mm on the rear when i finally changed my wheels. surely buying cheaper tyres is a false economy.
