Pneumatic wheels are tires that have an airtight inner core, or body, that is filled with compressed air. A pneumatic tire consists of a tread and a body. Modern pneumatic tires are generally made from synthetic and natural rubbers, fabric and wire, as well as various chemical compounds, including carbon black.
Pneumatic tires are the most common type of tires. They are used on many kinds of vehicles, including cars, bicycles, trucks, buses and motorcycles. The body of a pneumatic tire is covered by a tread, which is often reinforced with steel belting and provides traction and contact with the road.
The air pressure inside a pneumatic tire is greater than the air pressure outside it, which allows it to remain inflated, even with the weight of a vehicle on top of it. The air pressure of a pneumatic tire also helps to protect it against forces that could deform it, as well as providing a cushioning effect when the tire hits bumps on the road.
While pneumatic tires have many benefits over their old-fashioned solid counterparts, they do come with their own set of hazards. One of these is the possibility of a blowout, which is when the tire gets punctured and loses all its air. Having a tire blowout on the road can cause a serious car accident. Other problems that can occur with pneumatic tires are issues with air pressure and tire performance.
