Son just bought a 18' equipment trailer with 6000# axles on it. Pulls nicely with a tractor on it, but empty, it can start to bounce right on up thru the truck, and it starts to get worse after an hour of highway driving. Wheels are balanced. Pulling it with a 1/2 ton Chevy.
I went for a ride with him, closely watching the trailer from the mirror. I did not see any hobby-horsing going on.
I'm thinking the whole rig is not flexing and taking up the road bumps when empty, and that dropping the tire pressure from the 60 or 70# to 35-45psi will be adequate for an empty, or nearly empty trailer, and give some cushion to absorb road bumps with.
The fact that it seems to get worse after an hour of driving, seems to point to warm tire pressure going up, making harder tires, and making the whole situation worse.
Thoughts ?
