DallasS8

I own a 2016 S8 Plus. I currently have 285x35x21 tires mounted on the standard factory S8 OEM 21x9 wheels with a 112 lug nut pattern and a 35mm offset. I want to mount wider after market tires (295x35x20) on 20x10.5 wheels so the set up is flush with the chassis and provide deeper concavity. Question 1: Will this kind of wheel and tire set up fit into my wheel box clearing the caliper and/or rub against the fender? I have searched a number of wheel manufacturers but have not been able to find a wheel that will fit the parameters I outlined above. Question 2: "Is there such a wheel out there?". Please don't respond unless you are commenting on my specific vehicle trim (S8 years 2015/2016/2017/2018). Thanks much for any insight you can provide. If you have an S8 with the set up I am looking for, it would be fantastic if you could include photos. If not, a description of your setup will suffice.
