27-29 ps is about right for 32" tires. I'd go 27-28 around town, 28-29 when the Jeep fully loaded and on the highway.

I run my 31s at around 28psi for street use (much lower and it "chops" the shoulders, much more and the ride is harsh. Remember, the larger the tire, the less pressure you need (it's the VOLUME of air that holds the jeep up). Play around to see what works for you.

For serious off road use, lower your pressures WAY down (like 15 at the most, depending on the terrain). Makes sure you have a way to air them back up for the ride home ;)

Be wary of setting tire pressure solely on the chalk test. The chalk test is responsible for many tires having been underinflated by those who don't also know what a reasonable pressure would be. From what I read above, I suspect there are a couple underinflated tires represented in this thread. It's far better to be slightly overinflated than underinflated which causes a tire to run hotter.

I believe 50 is the maximum pressure rating. I can't think of a single reason you would ever go that high in a wrangler.

There is no valid reason to ever inflate an autommobile's tires to the air pressure molded onto its tire's sidewall. The pressure molded onto an automotive tire's sidewall is only its maximum safe air pressure. And that pressure would only be appropriate if it were supporting its maximum safe load which is about double what automotive tires typically support.

Pay no attention to that sidewall air pressure for a Jeep tire. The only time the sidewall air pressure should be used is for a trailer-specific tire when used on a trailer.
