Jeep: Replacing an ATV with a CJ - Tire Pressure Question

I'm coming to the conclusion that I can buy a used CJ instead of
trailering an ATV to where I want to ride, unloading it, loading it,
etc. etc. Not to mention dealing with the weather. And the CJ will go
just about anywhere an ATV will go.

However, I do a LOT of riding on washboard and/or rough roads. I
really like the fact the ATV is riding on only 3-4 pounds of pressure
on the tires- it really smooths out the bumps.

I'm guessing I can do the same with the CJ, but are there tires that
are made to do this with? I will be driving long distances on the
highway (100+ miles) to get to where I'm going. I'll be sticking to
dirt roads, very little will be truly "off-road." What I'm worried
about is if I'll be damaging the tires by riding on them with low air
pressure, only to pump them back up again when I get back on the
hiway.

Anyone have any experience with this? I appreciate your comments.

Yes, you should be able to "smooth " out the ride with lower pressure. 

Yes 

I meant about 15 to 20 on washboard roads, but not tore up roads.

You should be fine on the roads you describe. Try to get someone to take
you in a Jeep.
