With mine it rides really good with 5 or 10 psi but if you hit any size bump or dip it comes down and sounds and feels like there is no suspension. Put about 15 psi it is ok unless it is a bigger one but the truck is up 2 to 3 inches above what it should be and doesn't handle well. I wouldn't care much with the 15 psi in them but sitting that much higher is not good.
An on board compressor is pretty much a must have in my situation.
Also taking the T fitting out made a difference as I don't get the side to side rolling in side winds and uneven roads that I could feel with just the truck and would imagine having a trailer would be worse.
