After considerable thought and financial consideration I have come to the conclusion that it does not make sense to swap out the tires on my Z4. First, even if I get $800 for the tires, by the time I pay to have them removed and a new set installed and ship the tires to the buyer I will only net $500 for a set of tires that cost $1300. I have decided that I will do what a lot of other BMW owners are doing. I will live with the runflats and only drive my Z when the temps are above 30 degrees and there is absolutely no chance of freezing precipitation. For those that expressed an interest or made an offer, thanks very much.
