Re: If you guys get a FLAT!?!?
apkano and ppro have some good advice.
As far as rim damage from a flat - these low profile tires are not prone to flying off the rim like their older style and much taller sidewall siblings. In fact before my Xfire I had a 540i with low profile tires that I drove at 60+mph with less than 12lbs pressure from a small leak in a rear tire - felt mushy but not flat - that is one of the reasons why you have TRMS - it is hard to tell if you have low pressure tire pressure till it is real low.
