Ridge Grapplers PSI? I have a bit of wiggle now

That's what I was hoping to hear! I think as important as having the tires aired up properly to as not get them overheated, we also want a good contact patch as well for control. Dual rear wheels get hat stability through more tire contact and I was thinking mine, if over aired and riding on the inner tread only, I am losing the stability if a wider contact patch.

I'm getting new weights before the trip, as I am adding the Jack-It bike rack to the tongue. So I will give your advice a try!
