49 all round

Not sure about psi, but I am running 2.6 bar all round.

Probably increase back to 2.8 now, 2.6 provided more grip in the snow.

Dude, if that's the case then that is dangerously high. Maximum rating for most tyres tend to be around 51psi. So in your case you only need a warm day or a normal drive and the pressures would start to exceed 51psi. You will wear out your tyres prematurely but worse yet would be a blowout.

Get it down to 36-38 psi asap!

Hopefully your tyres are not damaged (imagine pulling on an elastic band past it's elastic properties - permanent damage or snap)

I used to use 34 psi but each time I visit my dealer they bring it down to 30 PSI !!!
I use 32 now and asked the dealer not to touch it.
my wheels are 17" though

fyi lads:
Thank you for your email to BMW Customer Information.

The tyre pressures for your BMW are shown as follows

Front: 215/40 R18 2.6 bar/37.7 psi
Rear: 245/35 R18 2.6 bar/37.7 psi

The air pressure is the same for both axles. I trust this guidance is useful but please do not hesitate to contact me should you have further queries.

36f/38r or 38f/40r for my RE-11's. My rear right tyre has been leaking though!! I think my valve stem might be damaged
