Order replacement hand truck wheels from specialty hand truck parts and accessory retailer Magliner or from general hardware vendors, such as Northern Tool and Equipment or Harbor Freight Tools. Each company operates an online storefront accessible from the respective main company website, as of 2015.
Hand truck wheels come in two styles: solid and pneumatic tires. When ordering replacements for a hand truck, order the same type, as the axle of a hand-truck is specifically engineered for that type. Solid wheels are more durable than their pneumatic counterparts, but only roll smoothly on seamless and even surfaces. Air-filled tires, in contrast, negotiate rough, uneven terrain better while still protecting the hand truck load from spillage.
In addition to replacement wheels and tires, the Magliner retail website offers replacement truck wheel brackets and axles. It also sells four-wheeled dollies, two-wheeled trucks that convert into four wheels, ramps and specialized water-jug hand trucks.
Northern Tool, as well as Harbor Freight, offers hand truck wheels and tires in a variety of sizes and materials. Beyond this, the hardware retailers each offer a material handling department of carts, dollies, trucks and other supplies to move items. The merchants also offer other departments that sell tools, equipment, clothing, housewares, pet supplies and structures.
