Hi everyone, I am in need of a bit of help and information. I have a 2007 cougar. Now I haven't put new tires on the trailer since new, and that is something that will be done. Now my brother was her...
There is a pre-bend in the axles. Looks to me like you're not overloaded and you've run the tires under-inflated, thus the extra wear on the edges. As long as both edges are worn equally, you probably don't have an alignment problem. Install new tires and take the rig to a truck spring/axle shop to have the alignment checked, just in case.
