Goodyear F1 Assymetric 2's-Not feeling the love at the moment!

[56OctyVRS]

Running at 40 psi cold will be near 46-47 psi when hot and you will be driving on the centres of the tyre and less rubber on the tarmac, hence less grip and turn in feel.  36psi is more than enough in the tyre for the weight of the car. The point of xl tyres is so you need less pressure rather than more. Id reduce the pressures in your tyres and the grip will increase as you have more tyre touching the tarmac.

If anything running at 30 psi will feel like driving a water mattress around. I don't think 30 psi can be the recommended pressure for 225/40R18 tyres, can it? What kind of pressures do you guys run with your Assy2's?

My old Octavia VRS mk2 recommended pressures were 29 front and 31 rear on 225 40 r18s. Never had an issue at those pressures and the car handled brilliantly.
