In some applications a solid tire may be the right product.
Solid tires are made of smooth solid rubber and are fitted around a metal band. They are cheaper to manufacture and easier to maintain, but solid tires do not get the same level of traction as a pneumatic tire, particularly outdoors. Solid tires are best for smooth surface applications, primarily indoors or on loading docks. They also help with handling in smaller spaces, as they facilitate a smaller turning radius.
