Hi guys, i'm currently looking at a set of wheels to stick on my 320i but im not quite sure if they will fit, from what i can make out they will, but the 17s i have on the car at the mo scrub a bit when i have a bit of weight in or going over bumps, im sure this is just the tyre size more than anything!
right the size of the wheels im looking at are 17's, width of 7.5" and have an offset of et45. could anybody help if they run the sam sized wheels for what tyres they run etc?
Cheers guys

You're going to need at least 10mm spacers.

And a 215/40/17 tyre is required.

thanks mate! better get saving for the wheels then
