I'll be selling my RFTs on eBay brand new.
I've read too much about problems and lack of performance with RFTs here and elsewhere. Trying to find a RFT on a weekend is still impossible. In my opinion, it's an experiment that has yet to be completed. I've driven 28 years without a blowout or even a flat. All the cars I've ever sold or traded in have had brand new spare kits in the trunk, and that's over a million kms of driving, easily.
Will the law of averages catch up to me? Who knows? Fact is, I'm going with proven and advanced tire technologies, not new unproven technologies.
Also I bought the 325i base model with an eye to upgrading my wheels for summer. So for summer I'll find something in 17" with a good summer tire (not performance though, I value comfort over performance).
