Wheel fitment question.: for the e60.. Need help
 

Hey guys. I have a 2006 530xi and I'm running on kw v3 suspension. I wanted to know if it was possible to run a 20x10.5 square set up on the car if the offsets are 45 on the rims?
The wheels are stretched already to cover the fender and I rolled both front and rear fenders. Experts chime in please.
