2. INTRODUCTION
Non pneumatic tire is named as “TWEEL’’ combination of
(tire-wheel).
It does not use a bladder full of compressed air.
It cannot burst, leak pressure , or become flat.
Inner hub is made of polyurethane spokes which support rim.
Spokes absorb the shock by bending and regains its original
shape again.

3. history
First non-pneumatic tire was invented by company “MICHELIN”
in the year 2005.
Big Tyre Pty Ltd in Australia built a prototype in year 2011.
Resilient technology and University of Wisconsin–Madison's
Polymer Engineering Center developed in year 2012 .
Bridgestone Corporation revealed Tire at the 43 Tokyo Motor
Show 2013.

4. DESIGN
 A Steel Center Hub That Bolts On Just Like A Conventional
Wheel.
 The Spokes Are Poly-resin And Can Deform Around
Obstacles.
 An Outer Tread Like On Conventional Tires That Can Be
Made In Different Patterns For Different Application.

6. HOW IT WORKS
The flexible tread and shear bands
deform temporarily as the spokes bend,
then quickly go back to the initial shape.

7. TESTING OF TWEEL
Tested On Audi A4 Up to A Maximum Speed Of 60 Mph
Without Vibration In 2005.
John Deere Is Currently Using It In Mowers.
Latest Testing Is Done By Han kook's Iflex Reached A Speed
Of 80 Mph Without Vibration In 15 July 2015.
 Tested In Five Categories –Durability, hardness ,speed, stability,
slalom.

8. Why polyurethane only
...vs. Rubber ...vs. Metal ...vs. Plastic
•High abrasion resistance
•High cut & tear resistance
•Superior load bearing
•Thick section molding
•Colorability
•Oil resistance
•Ozone resistance
•Radiation resistance
•Broader hardness range
•Castable nature
•Low pressure tooling
•Lightweight
•Noise reduction
•Abrasion resistance
•Less expensive fabrication
•Corrosion resistance
•Resilience
•Impact resistance
•Flexibility
•Easily moldable
•Non-conductive
•Non-sparking
•High impact resistance
•Elastic memory
•Abrasion resistance
•Noise reduction
•Variable coefficient of
friction
•Resilience
•Thick section molding
•Lower cost tooling
•Low temperature resistance
•Cold flow resistance
•Radiation resistance

10. benefits
 NO FLAT TYER-EVER.
 YOU WON’T NEED A SPARE TIRE.
 REDUCED C02 EMISSIONS.
 ECO-CONSIOUS.

11. ADVANTAGES
Eliminates air leaks or tire blow outs.
Responsive handling due to five times lateral stiffness.
No maintenance required.
Facilitate recycling.
Durability & Long Life.
Less environmental impact.
Can resist IED(IMPROVISED EXPLOSIVE DEVICE) and gun fire.

12. APPLICATION
They are used on some small vehicles such as riding lawn
mowers and motorized golf carts.
Military usage tweel deflects mine blasts away from the
vehicle
The airless tyres are also used in all-terrain vehicle(atv)
Nasa’s small pressurized lunar rover prototype.
