Just bought 4 new tyres for my 120d M Sport:

Front: Dunlop 205/50R17 W93 Bluresponse
Rear: Dunlop 225/45R17 W94 Bluresponse

These match the existing dimensions however these are non RTF and replace V89 / V91 so can take more speed/load.

The standard PSI is:

Front: 29
Rear: 32

Should it change and if so what to?

I run 32 all round now or up to 34 rear if I'm hooning.

Yeah, you'll probably prefer it with an extra few lb in them. I'd be experimenting with 34/35 psi, see how stable that feels.
