HELP:tire pressures
I need some help on tire pressures. I have BF Goodrich LT285/75R16 on my truck and all the pressure are different from each other. The tires have no suggestions on what the pressures should be. If any of you have these size tires on your trucks what pressures are you running in the front and what you are running in the rear tires since the pressures aren't the same n all four tires. Thanks

The tires that are on the truck are not the OEM tires from the factory. The truck was lifted and had bigger tires installed on them. All this was done either at the dealership or the factory. I know they did reprogrammed the computer to the bigger tires so the speedometer reads correctly. There is a sticker stating what the pressures should be with the OEM tires.
the reason there is no suggested pressue is because almost all vehicles will require a different pressure to be correct. :read:
what you need to do is get some kiddy chalk and a straight, dry road.
spread a lot of chalk across the entire tread on all 4 tires. one thick line on each will do.
then drive straight for 100 ft. stop
get out and check the chalk lines. if they are worn evenly, you are good to go. if the center is worn more, drop down a few PSI and try again. if the outside is worn more, raise up a few PSI and try again.
keep doing this until the line wears off evenly.
a good starting point is gonna be bout 32-34 in the front and 29-30 in the back for you, becaue your tires are a lil wider than stock, but do the chalk test to be sure
good luck

For many cases where other than stock size tires are installed that information on the door does absolutely no good.
My door sticker calls for 265/75/16's at 35 psi. Those tires are Load Range D.
My 285/75/16 tires are load range E, totally different pressure characteristics.
