Tire size question for Style 17 BMW wheels

[Mallard]

without tyre, an 8" et20 is as far as id go on

I tried an E39 split wheel on mine and the rim was flush with the arch

Ok, so with the 15" x 7" ET47 mm stock wheels, I should be ok using 225/45/15 tires and 10 mm spacers - for a ET 37 mm net offset - and using the stock suspension.

I guess I could just measure the available offset on the fender directly and know for sure.

Thanks,
