When you do get them, tell them to put 30psi not 45psi in the tires then do the chalk test from there.

You can use what others run as a general guideline, but to find out the best tire pressure for YOUR rig you'll want to do the chalk test.

How to chalk test

Sure my rig has seen the trail, but I wheel it like a soccer mom looking for a parking spot at Nordstroms.

Doing the math using weight and tire specs (load & pressure ratings), I'd be at 20 psi. I run the trails at 18-20 psi. No way on the street. Using that math assumes increases in pressure and loads are linear. Perhaps they're not.

Always follow a great leader. In the absence of a great leader, BE ONE.
