We have the factory 20" wheels/low profile tires on our 2012 Ram 1500 truck and they are very stable, handle nicely with or without the trailer. As good as can be expected for a solid rear axle truck.
We use 35 psi normal use as indicated on the door sticker. The tire max is 44 psi which is what we use when towing using a good weight distribution hitch (ProPride 1400).
