Research studies show that under-inflated tires are a major issue
today.
In the USAIn the USA
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).
In the EUIn the EU
38% of cars in the EU drive on under-inflated tires. This results in 5.3
billon liters of wasted fuel worth of 7 billion EUR, and an extra 12.3
million tons of CO2 released into the atmosphere.
So, we can say that we require a system is easy and inexpensive to
produce would bring enormous savings in fuel, pollution, and
human lives when implemented on a large scale.

3. Some Other StatisticsSome Other Statistics
A statistics show that tires which are under inflated by as
little as 2 psi reduce fuel efficiency by 10 percent.
Over a year of driving, that can amount to several hundred
dollars in extra fuel purchases.
One of reason for Road Accident is less or Insufficient
Tire Pressure.
Near about 10,000 injuries could be prevented per
year if all vehicles were equipped with tire pressure
monitoring systems.
GM offered these in CUCV(Commercial Utility Cargo
Vehicle) Blazers and pickups used by U.S. military.

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
Tire-inflation systems have three general
goals:

Tire deflation valves
Tire inflator hoses
To operate tire deflation
valve this is screwed onto
the existing tire valve. It
inflates the tire to a
required pressure.

9. TIRE MAINTENANCE SYSTEM (TMS)TIRE MAINTENANCE SYSTEM (TMS)
Similar to CTIS
It notifies the driver via
warning light(visible in
rear mirror).
After every 10 min. or
time period specified
system check the tire
pressure.

10. AIRGO SYSTEMAIRGO SYSTEM
1. When a tire loses pressure, due to a
puncture or other seepage, a series of
check valves automatically detects it.
2. The System then immediately draws
air from the vehicle’s pneumatic
system and directs it to each tire
requiring air.
3. The air pressure is delivered via the
trailer’s hollow axle housing.
4. The air then goes through the hub
assembly and into the tires. It is
completely isolated from the brake
system
