3. PNEUMATIC TIRES
A pneumatic or air-filled, tire
is made of an air tight inner
core filled with pressurized air.
The pressure of the air inside
the tire is greater than
atmospheric pressure.
Cushioning Effect.
4. DRAWBACKS
Puncture or Blowout
A blowout at high speeds can
lead to a dangerous car
accident.
Variations in air pressure
changes tire performance.
Can blow out by gunfire or
explosion
5. Introduction
The Tweel Airless Tire was first developed in 2005 by Michelin.
The Tweel name is a combination of the words tire and wheel.
Tweel’s hub connects to flexible polyurethane spokes which are
used to support an outer rim.
6. WHAT IS AIRLESS TIRE?
Airless Tires or
Non-pneumatic
Tires are tires
that are not
supported by air
pressure.
13. ADVANTAGES
Eliminates air leaks or tire blow outs.
No maintenance required.
Facilitate recycling.
Remains mobile even with some of the spokes are damaged or
missing.
Durability & Long Life.
Can take gunfire or explosion.
Less environmental impact.
18. CONCLUSION
No improvements are made in tires now a days.
Manufacturers have started to focus making airless tires.
Challenge is to make it more feasible and economical.
When done, Airless tires are the future tires.
