Well my run flats have finally reached the end of their life (29,000 miles) and I'm really looking forward to replacing them. I have a stock MCSC with 16's and I'm looking at 205/50-16 because according to the guys at the TireRack a 205/55-16 is too big. I do mostly highway driving with spirited cornering as much as possible. I also want to stick with an ultra high performance all season tire to help deal with the occassional Maryland snow. I've come up with a few candidates but I could really use the advice from some MINI owners to help finalize the decision.
