Going up a size with michelins

Last year I tried going up a size to make up for the 2mph fast speedo. Problem was I went with some continental tires that after digging in to them were reviewed as being mushy or having soft sidewalls. I'm needing some tires soon in the next couple months and was thinking about sticking with PS4S'. Does anyone know if they'll feel similarly? I know a bunch of people have gone up a size but I can't find anyone specifically talking about this.

I currently have 245/35/20 and 275/30/20 (Goodyear run flats which are awful) the. oem 759i 20s

I can't wait to get PS4S on the big question is can I go to 255/35/20 and 285/30/20?

I've seen calculation where the diameter variance is only 1%

my concern would be is the 8J sized front wheel limited to 245 and no more?

thanks

Yes, I'd stick to the 245/35 and 275/30 sizes on the "narrow" OEM 20s.
