Not nowing what WDH your using it's difficult to offer much help. Best I can do with no info is to point out that you need to be sure your trailer is level, or better yet, front slightly lower. If your using a WDH with chains, tighten it up one additional link. Perhaps if you post a bit more info, you'll receive some addition suggestions!
I totally agree with changing to LT tires, both on the truck and trailer!
