I have a 2004 530i with sport suspension. Would this size wheel and tire fit my car? Thanks in advance.

20 x 9 et20 / 20 x 10.5 et25

245/35/20 front
275/30/20 rear

 

the wheels will fit just fine. with those tires they are thicker than what is recommended according to rolling diameter. most do have those tire sizes though for a 20" setup to have more rubber on the wheels, and if needed you can always have the fenders rolled.

 

Thanks, NeRwEEzy. Would 285/30/20 fit for the rear? 20 x 10.5 et25
