This type of tire, called the "energy return tire" rubber, has a tread and tire wall that extends all the way to the inside of the tire pad, which causes it to lose less energy when subjected to impact and other stresses.
Bicycle tires use the same concept and of course have a lighter construction. The rim is made of carbon fiber and the stretched rubber is tightly wrapped around the outside of the rim. The adjuster can be used to make the tire stiffer or softer, and the model uses an open frame, but the tire wall can increase the effect of preventing debris from entering the interior of the tire.
Vacuum tires have been developed using a foam instead of conventional air, but the disadvantages are that it is not widely available. Although it is not necessary to worry about the benefits of tire pressure or stability, durability and cost are the main factors.
