The pneumatic tire or air-filled tire consists of a core filled with airtight sealed pressurized air. Typically, a reinforced steel belted tread or other type of materials, seals this inner core and provides the contact part with the road.
The tire will remain inflated with all the weight of the vehicle resting on it, because the pressure of the air inside the tire is greater than atmospheric air pressure. The pressure of the air inside the tire gives resistance against forces which attempt to deform the tire. This gives the tire a slight degree of a cushioning effect as the tire hits bumps in the road. If you have ever taken a ride in an old-fashioned carriage which had wooden wheels, you know how huge of a difference a set of pneumatic tires can make.
Pneumatic tires also come with disadvantages. Highly dangerous applications or high-performance situations for example, these tires could suffer a puncture and this would result in a complete failure. The consequence of a blowout at high speeds could lead to a serious car accident. Military planners must consider tires getting blown out by shooting of guns or explosion shrapnel. A vehicle crew's worst nightmare is becoming trapped within a fire zone due to all of their tires becoming flat. Airless tires evidently don't suffer from these issues and thus, in certain applications, can be more suitable.
The pneumatic tire may have problems as well with the variation in tire performance and air pressure. The lower pressure inside a tire could increase the traction and the comfort level. This is because of the fact that tires flatten slightly and more tread is touching the road. The pressure of the air inside of the tire works to maintain the "up and down" stiffness as well as maintain the lateral stiffness of the tire. Therefore, reduced air pressure allows the tires' sidewalls to flex. This leads to poor handling unfortunately. Within an airless tire, the stiffness in those two dimensions is independent.
Air pressure factors into other problems too. When it comes to maintaining correct air pressure, customers are notoriously unreliable. Improper air pressure inside tires can result in really unsafe situations. It is very essential to keep in mind that pneumatic tires are also prone to temperature changes, which can be responsible for changing the internal tire pressure. It is essential to take into account the kind of settings you would be needing your equipment to operate in so that you could check the tires on a regular basis and keep the machinery as safe as possible.
