Tires- NO they look like someone took something to smooth the treads on ONE tire. Rear pass side. I will take to a trailer place and check axle and such and also axles and bearings although bearings are NO LUBE but....
Brakes, The handle under the Prodigy does put the brakes on but putting the brake on in the truck does not seem to be working to put the brakes on the trailer completely, they do work a little and the thing that showes the amperage does show there is amperage being applied but not sure it is making it completely to the brakes. Can it be dirty contacts etc? I will call Tekonsha.
