Morning all. So my tires on the trailer are wearing in an unusual way. they both have flat spots and are wearing on the inner section. The tires are. 5.3x12 from Harbor Freight. They have 2000 miles on them, The original tires(4.5x4x 12 are not dry too rotted, just a bit smaller. The bearings have 2000 miles on them (did them the same day I put on new tires). The boat in question weight 450 lbs- 16 ft aluminum Starcraft with Mariner 9.9 tuned to 15. The trailers sits pretty flat on the truck, maybe >5* upward tilt to hitch.
