Tire pressure? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The correct answer imo is 'it depends'

If you don't carry much in the truck, I'd probably use 32 in front, and maybe 28 in the back. If you do carry a lot, use pressures closer to the max. The sidewall markings are really only good for max loads. The 'tire professionals' will always inflate them to the max: they aren't liable for anything going wrong if the tires are inflated to kidney-jarring pressures.

I just checked my owners manual on my '77 C10 just for grins...not a straight answer to be found, just a lot of pages of it depends/don't overinflate/don't underinflate/etc.

One indicator is the treadwear pattern. Is anything showing up? And what kinds of loads do you carry how often?
