I just had a set of wheel and tires put on my 91 525i today the rims are 17x8.5 offset is ET 20 The tires are 225/45/17 that I had on my other car. The problem im having is first the front rim or tire seems to be touching the strut its hard for me to tell if its the rim or tire because the car is lowered. There is also a wicked vibration in the front. Am I running the right size tire or should I try a new set of tires. Also my car is lowered using bavauto springs and bilstein sport shocks. Do I need a 5mm spacer in the front I thought I would not need spacers because the rims were the correct offset


Thanks
