COMPLETE SPECIFICATION
PLY TYRE TUBE
This invention relates to the use of about half round ply tubes in tyres.
One or two nylon plies are embedded in the lower side of the tube
which runs about half way. The upper half of the tube consists only of
rubber like ordinary tubes to facilitate expansion and flexibility. The
plies in the tube would reduce the chances of a puncher or explosion
even when a stone cuts through the tyre or there is air in the tyre
because it distributes the pressure around the cut or air. Most of the
stones would not be able to cut through the ply tube as it would be
pressed inwards to some extent and then the stone would be expelled
back or can be plucked out.
Even in some rare case if a stone manages to puncher such tubes, the
tube would not burst and the release of air would be slow and
therefore prevent the tyre from bursting. This can be proved by a
simple experiment—If we prick a balloon with a pin it would burst but
if we put a tape on it and prick it, it would not burst.
Most tyres burst when there is a cut by a stone or air in the tyre. This
can be prevented by using such tubes.
It works on a simple principle—It is easy to tear a cloth or something
from its edges or from a place where there is a cut but it is difficult to
tear the same material from the middle.
Such tubes would also increase the strength and loading capacity of
the tyre as it protects the lower side which is in contact with the

ground and is most vulnerable. It can be used in truck, bus, car, bike
tyres etc and can also be used by the military and mining trucks.
BRIEF DESCRIPTION OF THE DRAWING:
Fig 1 shows an example of a ply tyre tube according to this invention.
DETAILED DESCRIPTION OF THE PREFFERED
EMBODIMENTS:
Referring to fig.1 can be seen the ply tyre tube which can be used in
tyres.
No. 1—One or two plies which can be made of nylon or any other
suitable material embedded in rubber run about half way on the
lower side of the tube.
No. 2— The inner or upper half of the tube which is made only of
rubber to facilitate expansion and flexibility.
No. 3— Air valve.

I claim,
1. A new type of tyre tube in which one or two nylon plies are
embedded in rubber in the lower half of the tube. The plies can
also be made of any other suitable material or the number of
plies can be increased or decreased according to need. This will
reduce the chance of puncher or explosion of the tyre as
explained earlier.
2. Upper or inner half of the tube is made of only rubber to
facilitate expansion and flexibility.
3. The ply tyre tube substantially as herein described with
reference to accompanying drawing.

The ply tyre tube is a new type of tube which renders support to
the tyres even in case of a cut by a stone or air in the tyre. It
distributes the pressure around a cut or air in the tyre and prevents
the tyre from exploding. It also reduces the chances of a puncher.
Even in some rare case if a stone manages to puncher such a tube
the tube would not burst as explained earlier and the release of air
would be slow and thereby prevent the tyre from bursting.
It uses nylon plies which run about half way on the lower side of
the tube and protects the lower half of the tyre which is in contact
with the ground and is most vulnerable.
It comprises plies embedded in rubber (l),only rubber(2),air
valve(3).
