does anyone know whether smaller tires / wheels can be mounted on the 2002 530i w/ sport package. the current wheels are 17x8 (20mm off-set) with 235/45/17. i am concerned with the off set of the new wheels which are 16x7(15mm off-set) w/ tires 225/55/16. also it seems with 17" wheels the speedo calibration may be off(?) and if ride height is lowered with the sport suspension.
Thank You!

yeah they could.

You can buy such a combo at Tire Rack. (http://www.tirerack.com/snow/SnowSelectWheelSize.jsp?autoMake=BMW&autoModel=530i+Sport+Package&autoYear=2001&autoModClar=)

thanks,

i eventually got OER wheels(new) BMW style #82 (wide diamond spoke) and dunlop winter sport M2 tires from aaarims.[ 225/55R/16 (16x7 w/20mm offset]. the package w/ shipping ~ 1100$. one wheel however seems out-of-balance. i had them (all) re-balanced and the fronts moved to the back; still around ~72-75 mph, there is a slight vibration. i think that tire may need re-mounting.
the center caps for these wheels by-the-way ran about 43$. each.
