The pneumatic tire or air-filled tire consists of a core filled with airtight sealed pressurized air. Usually, a reinforced steel belted tread or other materials, seals this inner core and provides the contact area with the road.
The tire would remain inflated with all the vehicle's weight resting on it, as the air pressure inside the tire is greater than atmospheric air pressure. The air pressure within the tire gives resistance against forces which try to deform the tire. This gives the tire a slight degree of a cushioning effect when the tire hits bumps in the road. If you have experienced taking a ride in an old-fashioned carriage which had wooden wheels, you understand precisely how huge of a difference a set of pneumatic tires could make.
Pneumatic tires also come with drawbacks. High-performance situations or highly dangerous applications for instance, these tires could suffer a puncture and this would result in a complete failure. The consequence of a blowout at high speeds can result in a dangerous car accident. Military planners should take into consideration tires getting blown out by gunfire 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, can be more suitable in some applications.
The pneumatic tire might have issues as well with the variation in tire performance and air pressure. The lower pressure inside a tire can increase the comfort level and the traction. This is because of the fact that tires flatten slightly and more tread is placed in contact with the road. The air pressure in the tire works to maintain the "up and down" stiffness as well as maintain the lateral stiffness of the tire. Thus, reduced air pressure enables 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 issues too. When it comes to maintaining correct air pressure, consumers are notoriously unreliable. Improper air pressure in tires could result in very dangerous situations. It is really essential to keep in mind that pneumatic tires are susceptible to temperature changes also, which could be responsible for changing the internal pressure of the tire. It is really essential to take into account the type of settings you would be needing your machinery to operate in so that you could check the tires regularly and keep the machine as safe as possible.
