Sorry, hectic week, I only glanced at your sticker Fred and didn’t notice the psi difference. The only thing my brain registered was “goodness me there’s lots of numbers on there compared to mine and in my rush I’d forgotten to whizz my photo through a 90 degree turn”
I put the extra info down to the fact yours has DCC and factory 19’s.
A few psi like that would definitely make the ride a bit jigglier and affect the steering turn in, but is almost certainly more of an emissions led figure. The M135i also had 40 odd psi in the tyres.
With all the incredibly clever electronics on modern engines achieving super high power outputs despite cats and gpf’s strangling the exhausts it’s such an easy tweak to use tyre pressures to squeeze those last few digits of exhaust emissions under the target figure.
