My 4 door kick started "floating" on the gravel roads at about 80-85M.P.H this last weekend. Scared my wife when the car drifted to the right at 90. I imagine a sammy could experiance this at lower speeds with the shorter wheelbase.

Sign up for the next rally in your area.  80 - 90mph on gravel?  You're crazier than I ant to be.  :)

Good lord man, 36 lbs! I'm surprised that thing didn't bounce into low earth orbit first big bump!

It tried, the tire shop sent me out with 42psi! Needless to say I was very disappointed in my first ride in a samurai. Things are definitely improving.
Whats a guy gotta do to earn some respect around here?

I know my Tracker is heavier than a Sammy, but for reference I've found that with BFG 32X11.50 AT KO's To get a good compromise between handling and ride quality I ended up with 23/24 front and 19 rear for tire pressures. If I'm doing some serious off roading that requires climbing rocks or a traction sucking surface I go as low as 15/12.  When I drove out west I bumped that up to 32 and 27 to get better fuel economy but it rode like a wheelbarrow.

And the winner is... Tire pressure! Doing nothing other than reducing tire pressure from 36 to 27psi has transformed the samurai from a dangerous swerving mess into a stable vehicle. Thanks to all!

Glad to hear it was a simple fix.
