3. INTRODUCTION
• Robert William Thomson (1822–1873) invented the
actual first vulcanized
rubber pneumatic (inflatable) tyre. Thomson
patented his pneumatic tyre in 1845, and while his
invention worked well, but it was too costly to catch
on

4. WHAT IS PNEUMATIC TYRE?
• Pneumatic tyre is a tyre which is made of an air tight
inner core filled with pressurized air.
• The pressure of the air inside the tyre is greater than
the atmospheric air pressure, so the tyre remains
inflated even when the weight of vehicle resting on
it.
• It gives the certain degree of cushioning effect as the
tyre hits bumps in the road.

5. WORKING OF PNEUMATIC
TYRE.
• As we know, a pneumatic, or air-filled, tire is made of an airtight
inner core filled with pressurized air.
• A tread, usually reinforced with steel belting or other materials,
covers this inner core and provides the contact area with the road
while driving.
• The tyre remains inflated while driving due to high pressure inside
the tyre .
• The tyre air pressure provides resistance against forces that try to
deform the tyre while driving.
• If we have ever taken a ride in an old-fashioned carriage with
wooden wheels, we will come to know what difference a pneumatic
tyre makes.

6. TYPES OF PNEUMATIC TYRE
There are mainly two types
1.Air pneumatics
2.solid pneumatics
• Air pneumatics are filled with air while the solid
pneumatics are made of rubber and more puncture
proof.

TYRES

8. ADVANTAGES
Some of the advantages are it is able to,
• Move large loads.
• Absorb shock.
• Go offroad.
• Reduce noice.
• And also it is economic.

9. DISADVANTAGES
Some of the disadvantage are ,
• It is not puncture or blowout proof.
• Blowout at high speed can lead to dangerous car
accident.
• Variations in air pressure changes tire performance.
• It can blowout by gunfire or explosion.

10. APPLICATIONS
Pneumatic tyres are used in ,
• Lorries distributing goods.
• Motorbikes , Bicycles.
• Forklift trucks.
• Agricultural vehicles.
• Emergency service vehicles such as , ambulances, police
cars , fire engines.
• Automatic guided vehicles.
