Staggered tire size changes question
Hello Folks,
I have a 2014 550i MSport with the dynamic handling pkg. I am considering moving away from the RFTs. So the question goes like this: 1/ I currently have the 245/40-19 and 275/35 19 setup with RFTs. Is it possible to change to 245/35-19 and 275/30 19 instead using non RFTs? i find the tire ratio to be a bit too high and affects the road feedback i am receiving from the car. 2/ Does the equivalent non RFT handles better on track from the RFT version of the same tire and size? Thanks a bunch and sorry if these questions were covered in the past, just couldn't find a quick answer so far. Cheers, |

Pretty much any performance non-RFT will be better than an RFT. What tires do have now? If it was one of the OEM RFTs, none offered by BMW were "performance" tires. My original M-Sport RFTs were Michelin Primacy, which were "touring", summer tires even. I switched to non-RFTs after two months. You generally get better grip, smoother ride, better handling, and quieter with non-RFT. I currently have Michelin Pilot Sport 4S, and have previously had Pilot Super Sports and Bridgestone Potenza S-04. All were markedly better than the RFTs, the PS4S are the best of the bunch.
Can't answer about the sizing though.

I currently have Potenzas RE050A RFT and i’ve been quite surprised by how good they are for run flats. But soon i ll have to change em and will definitely go non run flats this time. But just wondering if i could go with a slightly lower profile since the sidewall need not to be that tall anymore... plus i ll have more feedback and better turn in response with lower profiles...
