Self-inflating tires are designed to constantly maintain proper tire pressure by detecting when pressure drops in a tire, notifying the driver, and inflating the tire back to the proper level. Research shows that over a quarter of passenger vehicles and a third of light trucks have at least one underinflated tire by more than 25%, resulting in billions wasted in fuel costs annually. Near 10,000 injuries could be prevented each year if all vehicles had tire pressure monitoring systems. Self-inflating systems work using a central tire inflation system, peristaltic pump, or similar technology to automate tire inflation and optimize performance, safety, and fuel efficiency.

2. SELF INFLATING TIRES
• Self-inflating tires are designed to constantly maintain tire
pressure at the proper level.
• Self-inflating systems are designed more for optimizing
performance and safety than for keeping a vehicle moving
on a tire that will no longer hold air.

3. SOME STATISTICS
• Research studies show that 27% of passenger cars and 32% of light
trucks have at least one tire under pressured by more than 25%. This
results in 1.24 billion gallons of wasted fuel per year (costing 3.7
billion USD).
• A statistics show that tires which are under inflated by as little as 2
psi reduce fuel efficiency by 10 percent.
• Near about 10,000 injuries could be prevented per year if all
vehicles were equipped with tire pressure monitoring systems.

4. FUNCTION OF SELF INFLATION
SYSTEM
• Detect when the air pressure in a particular tire has
dropped.
• Notify the driver of the problem.
• Inflate that tire back to the proper level.

5. PARTS OF SELF-INFLATING
SYSTEM

6. CENTRAL TIRE INFLATION
SYSTEM

7. TIRE MAINTENANCE SYSTEM
• Almost similar to Central Tire Inflation System.

8. AIRGO INFLATION SYSTEM

11. PERISTALTIC PUMP PRINCIPLE
(ENTIRE SELF-INFLATING TIRE SYSTEM)

13. ADVANTAGES OF SIT SYSTEM
• Increases safety, comfort and fuel efficiency
• Flexibility for drivers
• Future tires
• Better option to reduce road accidents
• Environment Friendly
• Marginal Production Cost
