You could run a 235/60r17 size tire if you want more sidewall. This is the size I use for my summer setup.

I wouldn't go below 29 psi on the front tire pressures and 32 on the rear as per the BMW manual recommendation.

Even a 225/65 r17 can work for a skinnier and taller tire. This is the size I use for my winter setup.

I should clarify that I'm using 17"x8" wheels.

Also, if you search on Michelin's website for example, it will show the safe "rim width" for each size tire under specifications.
If I look at Michelin Pilot MXM4 in 235/55r17 size it shows the safe rim anywhere between 6.5" and 8.5"
