ZCoupe 0 Report post Posted April 12 I'm getting advice from tyre retailers that I shouldn't consider replacing my run flat tyres with non RFTs as my car "is tuned for RFTs". Has anyone recently gone down the non RFT route and had any issues? Unfortunately not getting much useful advice from the local BMW sales/service teams. The reason I'm considering non RFTs is simply to offset the hard ride over road imperfections i.e. hoping the additional flex in side wall will help.

Palazzo 477 Report post Posted April 12 I changed my RFTs for non on my X5. It already had a spare. The ride is significantly better (to be fair I also changed from 21”to 20”), handling is no different, don’t think I would change back. But if you get a flat on a non RFT, it will destroy the tyre in less than 1km, on an X5 at least. Quote Share this post Link to post Share on other sites
