SPECIFICATION
This invention relates to light truck and passenger tires for enabling
vehicles to be driven on water
immersed roads and increasing mileage on dry roads.
When motor vehicles are driven, they are moving against air resistance, and
when an unexpected
amount of rain falls in cities, river bank overflows, or dike breaks, water
overflows low elevations
and the vehicles have to move against water resistance. Many vehicles in those
circumstances are
stranded. One reason is that, some of the cubic area of the vehicle displaced
by water reducing the
weight of the vehicle by the displaced water weight, which supposed to be
pressing the tires against
the road surface to produce traction between the tires and the road surface.
Driving on dry road have other problems, the separation of tires, which cause
minor, sometimes
major accidents, and slowing down the traffic when road blocks are erected, to
give access for
emergency vehicles. The majority of tires are simply worn out, and causing
unbalanced wheels,
which are corrected by replacing the tires by new or rethreaded tires, which
are eventually
discarded to increase the scrap tire piles in this and other countries around
the world.
When the tires are newly produced or rethreaded, besides natural rubber,
synthetic rubber is used
therefore increasing the demand to use up more natural recourses, in this case
oil, to produce
synthetic rubber.
I have found that the present invention will provide solutions for the above
stated three concerns.
One is, to enabling light trucks and passenger vehicles to be driven through
water immersed roads
and increasing mileage on dry roads, and enabling vehicles to be driven on
roads where water
receded and sediment of sand and mud covers the roads. Second is, to reduce
separation of tires.
Third is to obtain oil from other than natural recourses to produce synthetic
rubber.

To enable light trucks and passenger vehicles to be driven on water immersed
roads, and increasing
mileage on roads is achieved by incorporating impellers 2 in Fig.l and 11 in
Fig.5 on the front tires of
front wheels driven vehicles, and all tires on four wheels driven vehicles.
To reduce separation of tires is achieve by remanufacturing tires, rather than
rethreading tires. The
remanufactured tires produce better bond, because the whole side and tread
rubber is replaced,
rather than attached new threaded portion of the tire.
The oil required to produce synthetic rubber is obtained from scrap tires by
the process of Pyrolysis
technology, to be used for the impellers of the remanufactured tires, and to
newly produced tires if it
is found feasible.
The tire remanufacturing operation of Mobious is known by some in the industry
as bead
to bead remolding. The casings of the tires are obtained from good scrap
tires, rigorously tested and
found good in all aspects. During the process the rubber from the scrap tires
tread and sides are
grinded off and new rubber is bonded on the casings, as it is done when new
tires are produced.
Grooving the sides and the thread patterns of the tire, then the sides of the
tires pressed with logo
patterns under high pressure and temperature, which also cures the tire. Using
this method of
production the remanufactured tires cost reduced to about half of the newly
produced tires.
In the newly produced tires or the above stated Mobious remanufacturing
operation is made without
incorporating impellers to tires, therefore in this invention, both the new
tires operation and the
Mobious, or remanufactured tires operation is extended by incorporating
impellers at about the
sidewall veneering machine operation, where the impellers are incorporated in
the veneered rubber
sidings, one or both sides of the tires.
The array of impellers by the engine's power caused centrifugal force throws
the air or water in the
opposite direction of travel of the vehicle, which force in turn helps to move
the vehicle in the
3
CA 02578641 2007-02-08
forward direction. Similar result is obtained when the blades of the oar
pushed against the water in
the opposite direction of travel, which in turn moves the rowboat in forward
direction.
A newly produced or remanufactured tire 1 in Fig.l is showing a front wheels
driven vehicle's front
right outer side of the tire, having 16 impellers 2. The impeller's face 5 on
Fig.2 is shown by enlarged
pictorial view, and on its plan view the rounded end 6 on Fig.3. The travel
direction of the vehicle is
indicated by arrow 3 and the air and water resistance by arrows 4.
The front left outer side 7 on Fig.4 is the mirror image of tire 1. The
direction of the vehicle is
indicated by arrow 8 and the air or water resistance by arrows 9.
Incorporating impellers on both
sides of the tire is optional which will be directed by advantages or
necessity.
Another example of a remanufactured or newly produced tire 10 on Fig.5 is
showing a front wheels
driven vehicle's front right outer side of the tire, having 16 impellers 11.
The enlarged view of the
alternative impeller 17 is shown on Fig.7. The direction of the vehicle is
indicated by arrow 12 and
the air and water resistance by arrows 13.
The front left outer side of the tire 15 is the mirror image of tire 10. The
travel direction of the
vehicle is indicated by arrow 16 and the air or water resistance by arrows 14.
Incorporating
impellers on both sides of the tire is optional which will be directed by
advantages, or necessity.
Another possibility is to produce circular band units 18,19 shown in Fig.8 and
9, or 20 and 21 in
Fig.10 and 11. These units could be attached to the tire's sidewall rubber
coverings, extends from top,
down to the bead heel to newly produced tires made by the prior art, or
remanufactured tires are
made by the prior art of Mobious, without impellers.
In Section A, in Fig.12 is showing the height 22 of the impeller 2, which
height is between 1/4 and 2
inches, the cross section 23 of the circular band thickness is between 1/16
and 1/ 4 of an inch above
4
CA 02578641 2007-02-08
the sidewall rubber coverings of the tire, extends from top, down to the bead
heel of the veneered
rubber sidings. Both ends of the impeller 6 radii in Fig.3 is between 1/8 and
5/8 of an inch and equal.
In Section B, the alternative form of the impellers 11 in Fig.13 the face
height 24 at the middle of the
curvature is between 1/4 and 2 inches, and the thickness of the circular band
25 is between 1/16 and
1/4 of an inch above the sidewall rubber coverings of the tire, extends from
top, down to the bead
heel of the veneered rubber sidings.
The segment 26 in Fig.14 is for taking a cross section at C.
In Section C, in Fig.15 is the circular band 27 incorporating impeller 28.
The segment 29 in Fig.16 is for taking a cross section at D.
In Section D in Fig.17 is the circular band 30 incorporating impeller 31.
The impellers are incorporated as part of a newly produced tire,
remanufactured tire, or added as
circular band units, attached by vulcanization, or other bonding methods and
materials accepted by
authorities regulating the tire manufacturing industry.
Impeller 35 in Fig.18 is showing its rounded ends as half circles, which could
be an ellipse from the
minor axis. The tire is not shown, only its center 56. The radii centers of
the impeller align with the
radius of the tire. The center of the impeller close to the inner circle 32 is
the pivotal point for the
impeller, and also the pivotal point for angular measurements.
Impeller 34 from the pivotal point is showing 50 degree angular orientation,
although the maximum
suitable angular orientation could be 70 degree, opposite of the wheel
rotation 40, which tend to pull
forward and push upward the front of the vehicle, especially in water immersed
road, while impeller
36 shows 20 degree angle in the same direction as the wheel rotation, although
its suitable maximum
angular variation is 30 degree, which tend to pull forward and downward the
front of the vehicle.

Impeller 37,38 and 39 in Fig.19 is the mirror images of impeller 34,35 and 36.
Arrows 40 and 42
are showing the wheels rotation and arrows 41 and 43 are showing the forward
direction of the
vehicle.
The alternative impeller's front 45 in Fig.20 align with the radius of the
tire, which center is 56. One
end of the impeller close to the inner circle 54 is the pivotal point of the
impeller. Impeller 44 from
the pivotal point is showing 50 degree angular orientation, although the
maximum suitable angular
orientation could be 70 degree in the opposite direction of the wheel
rotation, which tend to pull
forward and push upward the front of the vehicle, while impeller 46 showing 12
degree angle, in the
same direction as the rotation of the wheel, although the suitable maximum
angular variation is 30
degree, which tend to pull forward and downward the front of the vehicle.
Impeller 47, 48 and 49 in Fig.21 is the mirror images of impeller 44, 45 and
46. The arrows 50 and 52
are showing the wheels rotation and arrows 51 and 53 are showing the forward
direction of the
vehicle.
Impellers Fig.18, 19 are placed in an equal distance from the center of the
tire 56. The example is
shown on a segment of a circular band, where the impeller 2 starting point is
about 1 1/4 inch inside
the inner circle 32 and the other end radius center is about 1 1/4 inch inside
the outer circle 33. The
length of the impeller is between 2 and 9 inches. The angle is measured from
the radius of the tire,
and the same radius crossing 1 1/4 inch inside the inner circle 32, and a line
from there crossing 1 1/4
inch inside the outer circle 33, which coincide the radius center at the other
end of the impeller.
Impellers 11 in Fig.20, 21 starting point is about 3/4 inch inside the inner
circle of the circular band
54, and the end point is established about 3/4 inch inside the circular band's
outer circle 55. The face
length of the impeller is between 2 and 9 inches. The angle is measured from
the radius of the tire,
and the same radius crossing 3/4 inch inside the inner circle 54, and a line
from there crossing
3/4inch inside the outer circle 55.

In new or remanufactured tires the thickness may gradual increased in the
veneered rubber siding
around the impellers 2 in Fig.l and 4, to increase the strength of narrow
impellers.
The presently designated four season tires, for example, would incorporate
impellers for water
immersed roads and increasing mileage on roads by the impellers backward
orientation about 0 to
about 25 degree within 50 degree as shown on Fig.18 and 20. Summer tires to
increase mileage on
roads by forward orientation of the impellers within the suitable maximum 30
degree orientation,
although in Fig.18 shown 20 degree, and in Fig.20 12 degree orientation of the
impellers. Tires for
enabling vehicles to be driven on roads where water receded and sediment of
sand and mud covers
the roads, the impellers are placed from 25 degree to maximum 70 degree
backward orientation.
The evaluation during and after experiments should provide the most
advantageous angular
positioning of the impellers to be used, which is a compromise between
forward, backward, or
aligned orientation, to be able to drive the vehicle on both, dry and water
immersed roads. The
experiment should also include the preferred inner and outer diameter for the
start and end points of
the impellers, including the preferred length, height, width, and the distance
for 57, which is between
1/8 and 1 inch for establishing the curvature for impeller 2, or measuring of
inside radius 5 to 9
inches.
