I am selling my tire trailer. It's based on the typical Harbor Freight trailer but is very well done (not by me, I'm the 3rd owner) and can support four 275 width tires on 17" or 18" wheels. It is designed to allow locking of the wheels via normal padlock. Nice diamond plate box (also locking) and floor. Flat four connector. All lights work. Newer bearings, almost brand new tires and good spare. Uses 1 7/8" ball. Also has frame for typical 20 gallon cooler on the front and 2" receiver on the back for adding a bike rack. Looking for $500.
