"Toe in" is for straight line stability at speed and reduced oversteer (spinning).
"Toe out" is for enhanced cornering and reduced understeer (plowing).
Excessive amounts of either will increase tire wear and induce serious handling issues.
I run zero toe, or slightly in, 1/16" at the most. I'm looking for tire longevity.
Zero toe can result in wandering, particularly with worn bushings or tires.
1/4" is way to much either way unless it's "out" AND you're running autocross events or on a very tight track. 2drs spin pretty easily and it's almost guaranteed if you chop the throttle on corner entry. You, also, don't want to make it easier to spin out when you get into the throttle. Go to the inside, if anything.
Wait... Why am I talking about race handling characteristics for a Wrangler?
Just go zero. If you have wandering and there's nothing wrong with the rest of your suspension, including tires, add a little "in" and as mentioned before, 1/16" is plenty.
Pulling to the right could be cross-camber and cross-caster built in to resist the crown in the road, except it would pull to the left in America. It could also be the ruts in the pavement worn in by the weight of semi-trucks. Experiment with one side or the other of a lane that has those worn ruts. Also, get on a known "flat" road and see if it pulls. If it pulls on a flat road, you could have other issues, something's bent...assuming you're not using a single, gas-charged shock as a stabilizer.
