Fixing punctures on RFT's - most do not do it b/c unless you know exactly when you punctured it, you cannot guarantee that you weren't riding around with a copromised tire for weeks, and the sidewall may have been compromised prior to the TPMS alerting you sine it was picking up the extra load.... Fact or fiction, I'm not sure, but it makes sense to me
My RFT's - they are sitting at the dealer to be put back on when the lease is up and I put Micehlin Primacy's Non-RFT's on the car. I carry the Continental mobility kit. IMO - ride is significantly improved. I don't cringe when hitting small bumps, or hear the road noise when on harder/concrete paved roads. Straight flat roads the GY LS2's were not bad and performed well, but everywhere else I thought they were harsh.
I also got AAA, and have BMW roadsize along with my local BMW dealer coverage.
Maybe in a few years the RFT's will get better, hope so, but until then I opted out of them. And maybe BMW will make it our choice to decide RTF or not in the future....
