I own an 07 328i that came with RFTs and I hated them, very noisey and poor wear. But they did provide amazing handling (cornering etc)
I switched about 20k miles ago to non RFTs (RE90s) and love them. They are quieter, handling is about 90% as good as the RFTs and that is still outstanding, ride is much smoother.
I rotate every 6k miles which further keeps noise down and helps extend wear.
I bought a Conti Comfort Kit in the event that a tire goes down but so far I have had no problem.
