What is Tyre
Tyre is fixed on the rim of wheel in
the vehicle. The tube in the tyre is filled with air. The tyre carries the weight of the vehicle and gives smooth ride to the vehicle.
Types of tyre
The tyre are classified into the
following types,
1. Solid tyre
2. Pneumatic tyre
3. Bullet proof tyre
4. Liquid filled tyre
Solid tyre
This type of tyre is a hard one made
up of special type of rubber. There is no tube in it. As it is a solid one it does not withstand vibrations. Hence this type of tyre is mostly not used in automobiles.Figure View of a Solid Tyre
Pneumatic tyre
This type of tyre is used commonly in all automobiles. The air is filled in the tube of the tyre and hence the tyre is called as pneumatic tyre. The photographic view of a pneumatic tyre can be seen in Figure.
The pneumatic tyre can be classified
into two types. They are
1. Tyre with tube
2. Tubeless tyre
Tyre with tube or conventional tyre
The tube assisted tyre is called as
the tube tyre. The photographic view of a tube tyre. The cross sectional view of the tube tyre can be seen in the Figure.
Tubeless tyre
This tyre does not have any tube
inside it. In this type of tyre, the tyre
is directly fitted on the rim. The cross
sectional view of the tubeless tyre can
be seen in the Figure.
Advantages
1. Simple in structure.
2. In case of puncture, the tyre can be
repaired without removing from the rim.
3. The tyre needs no tube.
4. Maintenance is low.
Bullet proof tyre
In this type of tyres even if the tyre
is punctured by the bullet, the air pressure inside the tyre does not decrease and the puncture is automatically corrected by the tyre itself. This type of tyre is used in military vehicles.
Liquid filled tyre
In this type of tyre the mixture of
15% of calcium chloride 85% of water
is used to fill the tyre for about 75% of
the total capacity of the tyre. This type
of tyre is used in some heavy vehicles
and tractors.
