Sorry if this has been asked before.
I have just become the proud owner of an R56 2007 with JCW
body kit and wheels.
I'm about to replace the Run Flat tyres 205/40/18 with non run flat 205/40/18 tyres.
Can anyone advise me on the correct tyre pressures please.
The run flat tyres are 2.4bar front and back which is 35 psi I beleive.
