    When I picked up my new Deere the rear tires where set at 20psi. Should I keep it that way or reduce it? Thanks

    I'd pump it up to about 50.

    My 997 had 35 psi when I bought it. I let it down to 15. I usually run 12psi but since mower is heavier I left it a little higher

    The rear tires on the 950 are the only wheels that u can put air in.

    I keep saying this to guys- READ YOUR MANUAL.:hammerhead::laugh:

    12 is what they recommend, and I have gone up a couple and down a couple from that, but 12 works and rides best.

    The reasons that they come with so much PSI are simple. One- to make sure they stay inflated unrtil sold since they are mounted on new rims, and not really being driven on to make sure the bead is seated tightly over new paint.

    The main reason though, is that they are shipped with the rear tires band ironed down tightly to the shipping crate bottom, and the added air pressure is needed to keep the band's pressure from popping the bead off the rim during storage and transport, and also to avoid damage to the tire itself.
