Need some help please. I recently purchased a set of rims for my 04 530i and I'm unsure if the correct tire size I should get for them. The rims are Size : 18 x 8 (F) & 18 x 9 (R) Offset : 20mm. Currently I have neither spacers nor has the car been lowered. I plan on getting some spacers down the line. Any help would be appreciated.

 

245/40/18 up front and 275/35/18 for the rears

 

How's that for service

 

Thank you, very much appreciated
