Tyre Pressure

[mav696]

Hi there, I've put some 22" alloys on and I was wondering what the best pressure to run these with as I know the problems with tyre wear is pretty bad with these cars.
Thanks

I have 20" wheels and have set the presures to 40psi all round. Now on 42k and still on 2nd set of Goodyear F1's. Also still on first set of discs and pads - so I guess it is down to driving style in the twisties.
