Your obviously going to run normal pressures on the highway, and other than some steering wheel feedback, if installed correctly, you shouldn't see any issues for normal driving. keep checking your tire pressures as beadlocks tend to deflated over time. As far as offroad goes, I would run about 8-15 psi.. dude you got beadlocks!!! Run them dudes as low as you can! The lower the tire pressure the better the ride, and the more traction you will have in sand.
