will I have any issues with rubbing ?
 

I have 18x8.5 with Nitto NT555 225/40/18 on Beyern rims in the front and 18x9.5 same tires 255/35/18 offset is 30 in the front and 45 in the rear on a 2004 330i.....please advise....thanks, Bryan

The front is a little aggressive as far as the offset goes but I think with a 225/40/18 you should be fine. The rears will fit perfectly.

Thank you so much...one more Q...
 

I was told if I wanted to get the rears even with the fronts to buy 15 mm spacers....is this true....?....thanks in advance....regards, Bryan

15 mm spacers....?
 

I have the rim and tires on the car and it looks good, however I want the rear tires / rims to stick out just a touch more than the front....is 15 mm the way to go....please advise....thanks

Please advise on the spacers....
 

Thank you in advance.....regards, Bryan

10mm would be easier to fit (you would still have to roll your fender)
If you want nice ballanced look and your rear wheels are one inch wider than front you need about 5 mm offset difference between front and rear. In your case ET30 front ET35 rear

It's not really whether it will look "flush" with the front, it's what will rub. If you do not want to do fender work, the rears will fit perfectly. That's the same size we generally recommend to our customers who are looking to put on wheels without the hassle of doing fender work.
The only way to tell what sized spacer you'd need is to measure it. Just get a ruler or tape measure and see how much further you'd like the wheel to stick, convert to millimeters, and purchase the spacer and bolts you'll need.:thumbsup:
