Flat-Free Tires & Casters: amzn.to/3EReNaZ Flat Free Tires are made of solid, lightweight, micro-cellular polyurethane foam. Our Flat Free Tires have the bounce and cushion of an air-filled tire with the benefit of no flats. No tubes; no re-filling with air; no more hassle! Our Flat Free Tires are non-marking, and because polyurethane is UV and chemical-resistant, they will not crack or rot as rubber tires do. Pneumatic (Air-Filled) Tires: amzn.to/3gmLcwO Air-filled tires provide great performance and are a less-expensive replacement tire option. Though they require more maintenance, they are cost-effective and provide a great bounce and cushion. Air-filled tires are lightweight and due to their price and performance are often chosen by OEMs for new equipment. Semi-Pneumatic Tires: amzn.to/3TZJRcO Semi-pneumatic tires are also Flat Free because they don’t go flat, but they do not provide the bounce or cushion of flat-free or air-filled tires. These tires are made of solid rubber with a hollow air pocket through the center of the tire. The air pocket is built into these molded tires, so unlike air-filled tires, they have no tubes or valve stems and cannot be inflated. The air pocket helps keep the price point down and makes the tires lighter in weight than a completely solid tire. Semi-pneumatic tires are generally less expensive than polyurethane tires and are best used on solid flat surfaces that are free from rocks and other debris that might stop a stiff wheel. Semi-pneumatic tires are often used on applications such as industrial hand trucks, lawnmowers, and other small lawn and garden equipment where tire cushion and performance are not as critical.
I’ve been researching wheels to upgrade my dog’s wheelchair. There is a surprising shortage of information on wheels in the whole internet.. Thank you so much for this video!
I've used the cheap HF 8" wheels on bicycle pulled carts and trailers for decades. They wear out fast (About 100 MILES!) So there's that. But other than bearing failure from poor lubrication, what's the problem with "speed rating" these for 15 MPH? They're all occasional use to satisfy the upper 5% of load cases. BTW I had the best luck, least maintenance, longest life by recycling full-sized plastic mag style wheelchair wheels. The solid rubber tires eventually stretched and came loose - and replacing them costs way more than a Thrift Store Chair. But for Zero maintenance and long service life - that's it. Just a bit noisy.
