An air-filled or pneumatic tire is composed on an inner core that is filled with pressurized air and sealed airtight. Normally, a tread made with reinforced steel belting or other type of materials, provides the contact area with the road and seals this inner core.
Because the pressure of the air in the tire is greater than atmospheric air pressure, the tire remains inflated even with the weight of the vehicle resting on it. The pressure of the air inside the tire gives resistance against forces which attempt to deform the tire. When the tire hits bumps in the road, this gives the tire a slight degree of a cushioning effect. If you have ever taken a ride in an old-fashioned carriage that had wooden wheels, you understand precisely how big of a difference a set of pneumatic tires makes.
Pneumatic tires also come with disadvantages. High-performance situations or highly dangerous applications for instance, these tires could suffer a puncture and this will lead to a total failure. The consequence of a blowout at high speeds can result in a serious car accident. Military planners must consider tires getting blown out by explosion shrapnel or firing of guns. The worst nightmare of a vehicle crew is becoming trapped within a fire zone due to all of their tires becoming flat. Airless tires evidently don't suffer from these type of issues and hence, in some applications, can be more suitable.
The pneumatic tire might have issues as well with the variation in air pressure and tire performance. The lower pressure inside a tire may increase the traction and the comfort level. This is due to the fact that tires flatten a little and more tread is placed in contact with the road. The pressure of the air inside of the tire works to maintain the lateral stiffness of the tire as well as maintain the "up and down" stiffness. Therefore, less air pressure enables the sidewalls of the tires to flex. This results in poor handling unfortunately. Within an airless tire, the stiffness in those two dimensions is independent.
There are other issues with air pressure. Consumers are notoriously unreliable when it comes to maintaining proper air pressure. Tires which have wrong air pressure can lead to dangerous situations. It is essential to note that pneumatic tires are prone to temperature changes too, that could be responsible for changing the internal tire pressure. It is very essential to take into consideration the kind of settings you will be requiring your equipment to operate in so that you can check the tires on a regular basis and keep the machine as safe as possible.
