hello guys I have a set of wheels 19x9.5 +22 square that I have for sale, in CASE I don't sell them, I'm wondering what tires I should run to make these work, I know I'll need spacers up front to make these work, I was thinking a 5mm spacer? Would that be enough clearance? Obviously I'll rub a 15-20mm spacer for the rear.
What tire size should I run? I was thinking 245 35 19 all around or 245 35 and 255 35? How about 255 35 all around? I am dropped on coilovers, so there's no gap between tire and fenders, with a 225 55 17 tires. I would rather leave it at this height if possible.

My car is a 07 530i RWD

I appreciate all your help
