Whаt pаttern оf оrgаnizatiоn is used to write this passage? Air-filled tires have several advantages over solid rubber ones, 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 smoother ride than solid tires, which make for very bumpy rides.
