End plates are made of .160-inch thick aluminum for superior strength and are then powder-coated to stand up to years of abuse. Center tubes are made of 1-inch O.D. tube by .125-inch wall thickness and a machined insert is welded into each end of the tube to provide threads for assembly. All racks come with 2 end plates, 3 tubes and are designed to fit 18-inch to 24-inch O.D. tires. Tires shown are for reference only and are not included with this item.
