Is it possible/ok to mount a 255/40/17 on a 8" rim? I have a set of staggered winter tires for my 2002 530i M-sport (235 front, 255 rear) that I'd like to mount on a set of used 17x8" rims that I have a line on. I've heard that it's possible, but I just want to know if it'll look odd or is dangergous.

Thanks.
