F10 M5 rear tyre width

[Dwaynos]

Hi everyone, I've posted this on M5POST but I'm not expecting many results as the forum can be a little slow sometimes.

Basically,
I'm getting closer to needing new tyres and still trying to find the best option. I really want to go for 305s on standard 20" m5 wheels. I understand that the recommended width is 10.5" but I also understand that the 305s can be used on 10" wheels.

I plan on using Michelins as they have been praised on the forums.

I'm looking at Michelin Pilot Sport 4S PS4S - 305/30 R20 (103Y) XL TL

Has anybody used these tyres without problems?

Thanks

305 will fit on 11" wheels, but not 10".
