Looking for 17” or 18” wheels with tyres

[Ukrobotman]

I’m running runflats on 19” rims and need something to soften the ride, looking for 17” 290 rims with tyres
I’ve got a 2013 E89 , not sure if earlier models have same wheel fitment . But need the od of tyre to match my existing 19 “ runflats

Non runflats will make a big difference so perhaps just swap tyres only?
