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.
