Self-inflating tires automatically inflate or deflate tires based on road conditions to maintain optimal tire pressure. There are several systems for self-inflating tires that use valves, pressure sensors, air sources, and relief vents. They detect low pressure and inflate tires back to the proper level. Future systems aim to make the entire process intelligent and more efficient. However, self-inflating tires are currently more expensive and complex than conventional tires.

SELF INFLATING TIRES

2. INTRODUCTION

3. What Is It…What Is It…
 The Self inflaTing TireS iS deSigned To
inflaTe or deflaTe TireS auTomaTically.
 TireS need more air while driving on
hard SurfaceS aT high SpeedS and leSS air
for driving on SofT SurfaceS Such aS Soil
or Sand.
The driver of The vehicle will SelecT an
appropriaTe Tire preSSure from inSide The
vehicle
meaningS :
 inflaTe : To fill (SomeThing) wiTh air or gaS So
aS To make iT Swell.
 deflaTe : To releaSe conTained air or gaS
from

4. INFLATING TYRES
Tires-inflation systems Job:
 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.

16. DisadvantagesDisadvantages
Too many componenTs
more cosTly Than The convenTional
Tires.
requires more mainTenance.
heavier Than general vehicle.
The user musT have The basic know
how of The relaTion beTween The
pressure and road condiTion.

17. ConclusionConclusion
self inflaTing Tires are going
To be used in The bicycles and
moTorcycles along wiTh The
four or more wheelers
Through ouT The world and
an era will definiTely come
soon when There will be
only self inflaTing Tires in
pracTice.
