Tire pressure?
I am trying to figure out the proper tire pressure for my 02 F250 SD PSD Supercab (long bed) with factory tires. Firestone Steeltex R45 LT265/75R16. The label on truck specs 50 psi front / 70 psi rear. Is this correct? The tires were running 65 psi all around when I took delivery. I have never heard of running a 20 lb difference between front and rear. Any suggestions?
Thanks.
Thanks.

Tire pressure?
[updated:LAST EDITED ON 04-May-02 AT 09:02 PM (EST)]Higher pressures are for higher loads. If you're not loaded down most of the time I'd think about less than 65 all the way around.
But apparently they feel that the rear tires, under full loads, must have their sidewalls compressed enough to warrant 70 psi to keep them the same working circumference (and thus going the same RPM as the front) if it is a four wheel drive, or (if it is a two wheel drive) the tires just can haul so much weight that the front of your truck and its occupants must not mean much to these tires. Nice tires! But overinflating even such nice load-handling tires for their intended use will wear out their centers first from them ballooning out due to too much pressure & the center of the tread pattern not being compressed enough (thus making it stick out further than the sides of the tire's treads can).
Again, I'd run 50 all the way around if and when empty if they recommend 50 for the front (which is already heavier than the rear when there's nothing in the bed). Pump 'em up for fifth wheel traliering or whatever your heavy load fancy is.

Tire pressure?
Hey, I run the same tires on my 2002 f250, but it is a shortbed. What about when I take my baby on the beach? What should I reduce my pressure to? 40? 35? 30? If anyone has ever run in deep sand they know this is crucial.

Tire pressure?
EnsHokie,
I don't know if this reply is too late, but I am a So. Calif. life guard. We drive in the sand all day long in our trucks and we run our tires at about 13 psi. Real low! But they work great and you will never get stuck if you know how to drive deep sand. They can also drive short distances on the pavement at road speeds if needed to.
Hope this helps.
