Lower Profile - Higher/Lower Pressure?

[Art0ir]

I know my tyre pressure is inside my fuel cap. But I've gone from 195/60/15 to 225/40/18's. What tyre pressure should I be using?

I run about 35psi on 225/40/18 etc

235/40/18 and I run 38psi front and 34psi rear. Guess manufacturer has some influence as well.

225/40/18 and I run 32psi

 

[barrie_d]

Mine are 225/40/18 and are at 33 psi

I was told (rightly or wrongly) that the pressure is more to do with the weight of the car rather than the size of the tyres. So I'd go with Gavins advice, stick with standard pressures and just keep an eye on them.
