Sure my rig has seen the trail, but I wheel it like a soccer mom looking for a parking spot at Nordstroms. To view links or images in signatures your post count must be 10 or greater. You currently have 0 posts.
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.
