I found some wheels that I may be interested in, the specs of the wheels are : 20x8.5 +32 and 20x10.5 +44 (e46 m3)... Based on the specs, with fenders rolled and te correct spacers used, would these wheels be compatible with my 2005 545i??

I'm a boob when it comes to offsets, so I apologize in advance for the noob question... Any type of response is helpful!

 

You will need spacers for sure. With right kind of spacers and tyres, you won't need to roll the fenders.

If you tried to mount those wheels without spacers, they would be sucked too much inside the fender, and probably rubbing the struts. With a spacer you will push them more out. For front I'd recommend a spacer of 15-20mm and 10-15mm for rear.

Thanks!!! Spacers of the with that kind of width are safe right?

 

I wouldn't put 20mm spacers in front, but if you buy quality spacers, you shouldn't have any issues.
