I've got a spare Bridgestone Potenza RE050A Run-Flat tire up for sale. It is the factory tire that came on the 335. I figured someone might need a spare for whatever reason (flat, end of lease, etc.), its still got some sufficient thread left. This size tire is 225/40R18.
I'd like to keep it LOCAL at the moment (I am in NJ), Ill let you know otherwise. PM me with an offer...
