Default tire psi?

What do you guys keep your tires at compared to the Max they say on them?
I have all terrains on that say 50 Max. They were at 35 when I checked. Should they be higher??

I like to chalk a straight line accross each tire and then drive forward. Adjusting the psi until there is an even line on the concrete. That tells me the tire isn't over or underinflated and should give me the best traction and life. It takes awhile to do though.

50lb_cat's method is the best way, but when in doubt go with the manufacturer sticker on your door. If you go up to 50 PSI you're truck will ride rougher, and you'll most likely wear the center of the tire a lot more than the edges. Many LT tires are designed to be used on any truck up to a 1 ton truck with a whole lot more payload than our little Blazers. The sidewall of your tire will have the load rating marked on it.

If you go with the method described by 50lb_cat you slightly over inflate your tire, or until the edges of the tread do not contact the road. Then draw a heavy chalk line (lots of chalk) all the way across the tread of your tire, then drive until the chalk marks on the pavement. Measure the chalk line to be sure it's the same width as your tire tread. Slowly reduce the PSI until your tire chalks a line the same width as your tire, and make sure you rechalk your line between each test.

Pressure in my tires is anywhere from bout 38 to 40. Gas milage as well as handling were improved

A good starting point for the chalk procedure is 10% less than the maximum inflation stated on the tire. If you set them to what the sticker in the door says, the shoulders of the tire will wear rapidly and give you a mushy ride. Wheel alignment is just as important as tire inflation.

I run BFG 30x9.5x15 AT's on mine and try to keep the pressure at 40psi on the street. I found I get the best ride and best mileage on fuel there.

i found most tires are about the same. i chalk my tires when i get them home and 30-35 psi is the sweet spot for all the tires ive run on my Blazer(28"-35" tall)

I always thought the "max PSI" was for installing , but I have been wrong before

Usually says something like "41psi at maximum load" in other words, with the vehicle loaded to its maximum.
