Best size tires for a 4'x6' utility trailer for long freeway trips

Yes, Dexter. The Lowe's website confirms your suspicion. 5x4.5

What do you do about the diff?

Leave the oil in and let it spin. Or remove the spider gears.

If you leave it to spin, have it turned around backwords and rig up some LED lights on the pinion flange. That'll distract the drivers behind you.

My reason for trying for the same tire and wheel as your truck is so you only need to carry 1 trailer spare. The truck already has one.
