We're gearing up for a road trip in a couple weeks and I'm considering pumping up the tires to 52psi. I used to pump my Rover's tires to eek out the extra 1mpg, which was an 8% increase, but I wonder if I would see a similar result in the R1T on 20" ATs, a ~25 mile range gain?

Has anyone tried pumping them up more for better range? Any concerns about wear and tear, stopping ability, etc?

I would run higher pressure in my Bolt to get better range, but I'd be somewhat concerned that the AT tires would end up wearing unevenly.

Yeah, that's where I usually fall. On any vehicle higher pressures increase wear on the center of the tires and make both ride & handling significantly worse. Those aren't worth the marginal efficiency gain to me.
