As title. Just wondering. There's an old thread but the answers didn't look conclusive. Only started thinking about tyre pressures as I've just been out giving the car some beanz adjusting boost. Thought I'd see what the garage had filled rears with (new tyres last week in rear) and was horrified to see they'd put 40psi in them. Now the back has been twitchier but I put this down to the recent addition of locking subframe collets, also had better mpg...... But....40psi!!!!!.
Always ran 32psi front and rear before.
Any ideas?
