2015 Bmw Z4 Tires

I suffered for several months about whether to put new run flats on my 2015 BMW Z4 and thought about going to a non-run flat tire for less noise and potentially more comfort. I finally elected to settle for the dealer recommended run flats (the Bridgestone DriveGuard tires) to have the security still of being able to drive without a spare tire. I am very pleased to confirm that the road noise is significantly reduce from the replacement of the old run flats and the comfort has significanlty increased. I have no regrets from sticking with the run flat approach and these tires in particular!
