    No no, no need to take the poor souls out from the car and then fill up.

    You can safely adjust tire pressure with occupants remaining seated in the car.

  2. hahahahaaha. Obviously :p.
    I generally keep the tyre pressure at 36 up front and 33 at the rear for my T-JET+. Cannot plan when the car will be fully loaded or only one person in it. Going to a filling station every time when its fully loaded is not exactly practical either.

    Maybe i am not being clear. The fully loaded car and empty is a difference of approx 250 - 300kg.
    Should 36/33 be measured with the 250kg on board or should it be measured before loading the 250kg.

    The volume of air going in would be different in each case. :)

    That is what we are saying. You can fill your tires with or without 250 kg on board. It does not make a difference.

    I always keep 32 in front wheels and 30 in the rear whether with full load or with me alone in the car. It gives me clearance enough to avoid most of the speed breakers in bangalore.

    Stick to what the user manual says .
    Or else look at you're drive side door you will mostly have tire pressure details there( In my case it was not written)

    Nitrogen is a gimmick if you ask me, Its a simple waste of money.
    There has been no conclusive proof that city driving is any better with nitrogen than it is with regular Air.

    Some useful facts

    Following picture will illustrate the temperature difference at two different tire pressure condition. Always stick to correct tire pressure.

    For a gross vehicle weight of 6840lbs, tire carrying capacity at 30 psi is 6840lbs and for 20 psi it is 5610lbs. Tires are 1230 lbs overloaded(bases on 235/75 R15

    Here is the photo of a 30 psi(left, correct value) and a 20 psi tire. Visually they don't make any difference.
