    Same as manufacturers specifications, its not an amount of air, but a percentage, per square inch. I usually add 2psi to low profile tyres.

    Dunno about adding 2 psi for low profile tyres?

    But Jace is right. Look in you owners manual and look at the biggest tyres for the car (usually 16" rims).

    Inflate them to that pressure.

    I'm only going by what TSW say on the bit of paper that comes through with all their wheels at work.
    I run 32psi, it's probably higher than recomended, but I find the car drives nicer and drifts better!

    :shock:

    Drifts better?

    Does that mean your losing traction around corners?

    A sure sign of over inflated tyres? :shock:

    It's not that bad that it just understeers all the time, it still handles really well.

    But if I wanna throw the back end round the odd corner or empty roundabout I can.

    God it sounds like I drive like a right ****. It's not that bad!

    Its a convertible, and 18's are an option but they come with 225/35/18, mine are 215/35/18 so i'll just add a couple of extra Psi to what it says in the book
