    what is the best tire psi for the 02 gls.the door panel says 30 for all tires.
    i guest it depends on the type of tire you using too...........

    Usually with plus-sized wheels it's nice to run a little higher pressures because lower profile tires can typically support more pressure without bulging. And the extra pressure will help prevent sidewall rollover and potential wheel damage.

    But with OEM-sized tires 32 psi would be good. Or try 36 psi front / 32 psi rear as Bnystrom has said. The front tires hold 62% of the weight of the car, so it can help to inflate them more than the rear.

    32 psi is a generally good all around...I like to run them at about 34 psi for fuel economy.

    you should also consider temperature. since you live in new jersey where its a little colder, you might want to inflate accordingly. lower in the winter, for good traction in snow. Higher in the summer.

    If you go to the Yokohama tire website, they talk about tire pressure and one engineer had a basic general formula for figuring out what tire pressure to run. These are not the best settings, but they are ideal for most setups according to Yokohama.

    The formula was:

    (weight of car) / 100 = tire pressure
    add +2 psi for the heavier end
    if you're using stock suspension, add +2 psi all around.

    thats probably refering to the max load rating ie; you can carry so many pounds of weight at 38 psi cold.

    ok I used to do tre work for a living.
    go with the door pannel, unless you are loaded up and on a trip you can add 2-3 psi more in Other than that you could cause uneven wear to the tires or cause the car to ride rough.
