This presentation is all about the latest innovation of the air -free tire concept by BRIDGESTONE, in the automobile sector. this will tell us how such tires actually works and has an edge over normal and tubeless tires.
The wheel is probably the most important mechanical invention of all time. The wheel has been continuously driving our civilisation like a catalyst in a chemical reaction. Nearly every machine built since the beginning of the Industrial Revolution involves a single basic principle embodied in one of the mankind’s truly significant inventions.
Tyre is a hoop that covers a wheel, around the wheel rim to protect it and enabling better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.
Creating a new non-pneumatic design for tyres has more positive implications than one might think. For one thing, there are huge safety benefits. Having an airless tyre means there is no possibility of a blowout, which, in turn, means the number of highway accidents will but cut significantly. Even for situations such as Humvees in the military, utilising non-pneumatic tyres has a great positive impact on safety. Tyres are the weak point in military vehicles and are often targeted with explosives. If these vehicles used airless tyres, this would no longer be a concern.
There is also an environmental benefit to using this type of tyre. Since they never go flat and can be retreaded, airless tyres will not have to be thrown away and replaced nearly as often as pneumatic tyres. This will cut down landfill mass significantly.
Because of the benefits, I believe that it is extremely important that research and production of airless tyres are continued and increased. This type of innovation works well in conjunction with several engineering codes of ethics, and thus should be embraced by engineers everywhere. Cars are things that people use every day, so any improvements over existing designs would affect the lives of the majority of people. Learning about such a topic, therefore, I believe holds extreme value- especially for us freshmen engineering students. In doing research for these kinds of topics that hold significant meaning, we can see that what we will do can make a difference.

3. INTRODUCTION
Tyre is a rubber member which gives the
cushion to the automobile. It consists of outer
cover i.e. tyre proper and tube inside.
The tyre-tube assembly is mounted over the
wheel rim and air inside the tube carries
entire load and provides cushion.
3
4. Functions of tyre
To support the vehicle load.
To provide cushion against the shocks.
To transmit driving and braking forces to the
road.
To provide cornering power for smooth steering.

7. Advantages of tubeless tyres
Lesser unsprung weight.
Better cooling.
Lesser rolling resistance.
Comfortable ride.
Slower leakage of air.
Simpler assembly.
Improved safety.
8. NON PNEUMATIC TYRES
Bridgestone Corporation announced it has developed
“Air Free Concept (Non-Pneumatic) Tire” at the 43
Tokyo Motor Show 2013.

9. INTRODUCTION
Since the earlier invention of a non-pneumatic wheel in
1920’s, the non-pneumatic tire (NPT) is getting more
attention due to its advantages over the pneumatic
counterpart.
Many design studies are still needed from the viewpoint
of material, pattern, and structures.
However, no systematic research for such important
design issues has been reported in the literature up to
now.
9
10. The airless tire is not a new idea –
“MichelinTweel” is just another example - but
Bridgestone claims that this is the first design of its
kind that is ready for mass production.
10
11. What makes tyres “AIR LESS”
• Structure of spokes stretching along the inner
sides of the tires supporting the weight of the
vehicle.
• A synthetic resin that becomes flexible when
heated, can be processed into a variety of
shapes, and becomes hard when cooled. The
changes from heating and cooling can generally
be repeated, making it easy to both mold and
recycle the material.Untitled.mp4
14. ADVANTAGES
The tires require less maintenance
The worry of punctures is eliminated.
The materials used in the tires and the spoke
structure are 100% recyclable.
Provides low rolling resistance and
contributing to reductions in co2 emissions.
Nothing to do with fuel efficiency in a direct
way, only offering the benefit that it will never
influence consumption.
15. Increased versatility
Using high-strength but flexible highperformance resin as a material has increased
versatility through improved load-bearing
capabilities and driving performance.
High-speed travel (maximum 60 km/h) in
ultralight vehicles has also become possible.
15
16. Low rolling resistance
• About 90% of energy loss from tire
rolling resistance comes from
repeated changes in the shape of tires
as they roll. Bridgestone has
succeeded in making a significant
reduction in energy loss by using
proprietary materials technologies
and simplifying the structure of the

ConCept tire” hAve AChieved the same
versions.
19. Michelin first announced the Tweel in 2005
The name is a combination of the words tire
and wheel because the Tweel doesn’t use a
traditional wheel hub assembly.
A solid inner hub mounts to the axle. That’s
surrounded by polyurethane spokes arrayed in
a pattern of wedges. A shear band is stretched
across the spokes, forming the outer edge of
the tire (the part that comes in contact with the
road).
20. The tension of the shear band on the spokes
and the strength of the spokes themselves
replace the air pressure of a traditional tire.
The tread is then attached to the shear band.
The Tweel looks sort of like a very
large, futuristic bicycle wheel.
21. When the Tweel is put to the road, the spokes absorb
road impacts the same way air pressure does in
pneumatic tires. The tread and shear bands deform
temporarily as the spokes bend, then quickly spring
back into shape.
23. Bridgestone vs Michelin
Bridgestone’s prototype version looks very
similar to that of Michelin.
In Michelin’s design the thermoplastic fins are
staggered so that the connections to the hub
and the rim won’t torque causing complete
structural breakdown.
23
24. The biggest difference between the two tire maker’s
wheels, as pictured above, is the size of the supporting
ribs. Michelin focused on allowing the tires to be able to
deform over obstacles, making them more suitable for
military applications
where as
Bridgestone has approached its tire from the consumer

angle, creating a highly recyclable tire that will cut down
25. FUTURE CHALLENGES
• Goodyear in collaboration with
NASA Glenn Research Center
(GRC), develop non-pneumatic
tyres for use first on the moon,
and eventually on Mars.
25
26. • “The basic rubber-pneumatic design used on
Earth does not have the same utility on the moon,”
said NASA Principal Investigator Vivake Asnani.
• There are no lunar roads. Lunar tyres need to be
designed to develop traction on sandy undulated
terrain, in regions that humans have never even
seen up close.
26
27. • The Spring Tire has now been recognized
with a so-called “Oscar of Innovation” at
the 44th Annual R&D 100 Awards in
Orlando, Florida.
27
The airless tire is not a new concept and is under investigation by several tire manufacturers since a while
Tubeless tire technology does away with the need for an inner tube thereby increasing safety.[citation needed] In a tubeless tire, the tire and the rim of the wheel form an airtight seal, with the valve being directly mounted on the rim. If a tubeless tire gets a small puncture, air escapes only through the hole, leading to a gentle deflation. Conversely, an inner tube could potentially burst like a balloon, leading to a rapid deflation of the tire which could result in sudden loss of control of the vehicle.
no need to periodically refill the tires with air
“cradle to cradle” process that maximizes the cyclical use of resources from worn tires into new tires and the use of recyclable resources.
