Not where to put this exactly, Ive tried M Power but not much response.

Just ordered a set of genuine CSL wheels for my Z4 M Coupe. They will arrive next week with PS2 tyres on.

Anyway, What is the best tyre pressure to run these at?

Currently I keep my pressures at the upper end of the scale that BMW reccomends. I have no real evidence that this is best, but it seems to work well for me. With some fairly hard driving and one track evening they seem to have worn out very evenly, which I guess is good sign. The grip seems to be fairly predictable too.

Anyone got any real knowledge about what is best and why?
