For on road use most tires are good around 30 psi on a Jeep.

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.

To make a pressure recommendation, we need to know what size tire you're running.

The best way to tell is by the contact patch. Get a tire crayon or a white marker. Mark across each lug across the tire, go for a short drive , check each tire, adjust each tire pressure until the marks wear off evenly.

Doing it this way the tire will wear down evenly. and ratate every 3k

Down under we go metric so they are 245/75/16 hope that helps...
I'm currently running them at 36psi but I like the idea of the chalk...

That's roughly a 31" tire for us Americans and 30-31 psi would be about right for that. 36 psi is a little excessive which can cause uneven tread wear. Generally speaking, the bigger the tire, the lower the air pressure you run and for factory size tires like 29-30", the factory says 31-33 psi.

Thanks Jerry!
Will run them at around 32psi and monitor the ware as well by doing that crayon trick across the tread.
Much appreciation!...

Why 32? As described above, 30/31 (unloaded/loaded) is about right for a 31" tire.
