But once you enter an ORV park, things change, and with your tires throwing sand, they will cool at such a fast rate, it is essential to have a high pressure

Each tire is different.. play around with it....when I ha my YJ I ran the rear around 1-2 lbs less than the front due to the weight difference...... if you go to low... go to David Allen Racing and air back up :)

I run the boggers on my CJ5 at 3-4 PSI up front and 1-2 PSI in the rear if the sand is really dry, 6/4 if its damp.

you do that and you WILL get stuck on the entry road. I have 33" thornbirds, and I run 1/2 to 1 psi. I was running b/t 8-10 and they still dug in a lot, not as much as 25-30, but they still dug in.

As low as you can go, or as low as you feel safe going....it takes a lot to make them thornbirds squat. have fun!

I would suggest just buying new tires...........but if that is out of the question 5-9psi should work. Tbirds have stiff sidewalls and need to be run at lower pressures. Especially with your 4cyl.

Ive said it before, and Ill say it again. Do NOT go on the dunes without first checking your Muffler Bearings. Also, top off your blinker fluid.
