Air-filled tires hаve severаl аdvantages оver sоlid rubber оnes, according to the chief engineer for product design at the Akron Technical Center of the Goodyear Tire and Rubber Company. For one thing, air-filled tires, also known as pneumatic tires, are less expensive than solid ones. Also, pneumatic tires are lighter and thus easier to handle than solid tires. Third, the rubber foam that is inside of all-rubber tires quickly builds up heat because of internal friction, causing the foam to melt, but pneumatic tires do not build up such heat. Finally, because pneumatic tires are more yielding, they offer a much smootherride than solid tires, which make for very bumpy rides.
