widest 20” tires and rims

[Glaferri]

Looking for widest 20” tires and rims I can fit on my 2019 M850i coupe (G15).
I was thinking:
Front 9.5 rim (5x112) 275/35zr20
Rear: 10.5in or 11in rim (5x112) 295/35zr20 or 305/35zr20
Would that fit? What would be the ideal offset?
Can I install wider than that?
Thanks for your help!

Front Size: 20" 245/35-20 Load Class: XL Rear Size: 20" 275/30-20 Load Class: XL

Factory tire size is listed, are they not large enough for you ?

No. If they were large enough for me, I wouldn’t ask the question.

Hi I have M850i I put m8 gran coupe wheels on 285/35/20 rear and 275/35/20 front. Omg fits perfect and took out all the gap. People think I have spacers. Looks terrific. I lowered my car with h&r springs and no gap in the rear.
