Hot take: an old timer at the gas station changed how I think about tire pressure
I was airing down at a station outside Moab last weekend when a guy in a beat up Land Cruiser asked what I run my tires at on slickrock. I told him 15 psi and he just shook his head and said try 12 and watch how the sidewall wraps the ledges. I figured he was full of it but dropped to 12 anyway, and the difference on the Fins and Things trail was night and day, way less spinning and the rig just walked up stuff. He also told me to carry a real gauge not the one on the hose because those things can be off by 4 psi or more, which I never even thought about. Been wheeling for 8 years and nobody ever told me that. What psi are you all running on sandstone?
That part about the hose gauge being off by 4 psi is so real, I checked mine against a good dial gauge last year and it was reading almost 5 high, which means I'd been airing down way less than I thought for years. I run 12 on the sandstone now too and it's a whole different rig, way more grip and the tires just mold around the rock instead of skipping across it. Funny how the guys who've been doing this the longest are the ones still teaching us stuff.
