Those are the tires for my son's off-road wheel chair. He has CP and is unable to move his arms and legs. We struggled for a year or so shoving his regular wheelchair through the dirt and sand. Finally we found a company that makes a chair for the beach. It also works great for the mountains. Since we live at the beach and spend lots of time in the deserts and mountians, this chair is an essential part of our gear. It takes up a lot of room, but the smiles it provides are worth the extra effort.
