I fitted MSS Springs to my G31 best thing I could have ever done, still riding on 20” wheels

Hi, so if I have staggered set up now (2x 245/35/20 and 2x 275/30/20) can I go all square to 245/40/19?

If I change to 245/40/19 and 275/35/19 will this change riding comfort?

I have adaptive suspension!

Will this not affect speedometer?

I was going by this chart:

Twenty-inch wheels and low-profile tires have the same problem here if you live in certain states and/or experience harsh winter weather. Given their degraded ride, cost and added weight, they seem to me to be little more than expensive fashion statements. I've have had three new BMWs since 2016 and prefer 17-inch wheels and tires (if I can find them here in the US) for my winter tire set. You're lucky in Europe to have a plentiful supply of 17" wheels.

Hi,
I currently run 19’ 8J 245/40 both front and rear as my winter set. I want to get a 20’ OEM series 8 wheelset 8/9J. I’m wondering if I should go with 245/35 fronts and 275/30 rears or 245/40 f and 275/35 r.
Thank you!
