    hey guys.

    As per the title really, what would be the approx air preasure to put in a tyre of size 205/40/17??

    reason im asking is my new car has wheels of this size but came with 15's standard so have no idea what they should be lol

    its a 206 GTI if that helps at all

    IIRC it doesnt matter what size the tyres are. The pounds per square inch (PSI) of the tyre will be the same in a 13 inch as a 20 inch, theres just more "inches" of the tyre to inflate in a 17". That probably makes no sense whatsoever!

    I just whack about 35psi in mine all round (13") which is probably a little too much but fuel economy ftw! What you've put in sounds fine.
