Hey Guys,
I changed my rims on my E92 335 and F30 without any issue from the dealership. I even used non runflats tyres with no issues.
Just be weary that the aftermarket rims may not handle the hard runflat tyre well. I had M6 aftermarket rims on my E92 335, with pirelli runflats.
The rims started cracking due to our poor road conditions and the hard run flats.
