RFT 19inch changed to normal tyre
I changed my 19 inch Bridgestone Potenza RFT's to conti Sport contact 5p's (non runflat). Made huge difirence to smoother ride and road noise. Also got a mobility kit from dealer which is an electric pump that runs off gig lighter connection. Comes with pucture sealantt in case of emergencies.
Difficult to get this size in other makes of tyre. (255/30's and 225/35's). I hear new Bridgestone S001 non runflat is quiet. I have Michelin Pilot 3's on my 5 series and they are the best in my opinion. (couldnt get the right size for the Z other wise i would have gone Michelin.). So far very happy with Conti's.
Still want to to do more sound insulation in wheel wells and door wells. I will use a combination of foam and Dynamat.
