I have a 92 E34 535i and I am planning to mount 93 M5 Throwing Star Wheels that I bought. I am between 2 tires and can't decide which tire to go with. The car is used everyday and is driven in Philadelphia (bad streets, pot holes) The two tires are Dunlop SP 9000's and Michelin XXGT Z4's size 235/45 ZR17 Any input would be great!
