I have 3 Stock Bridgestone Potenza RE050A run-flats for sale from my 135i:
1 from the left front (215/40/18) - $180
2 from the rear (245/35/18) - $200 ea./$400 for the pair
I picked up a nasty screw in my right front tire at 2800 miles and replaced the tires with a set of non-run-flats. Buyer pays shipping. Drop me a PM if interested.
Thanks,
Mike
