    Airless Tyres: Sandeepa Chikkalli (2GP16ME038)

    This document summarizes a student project on airless tires. It introduces the tweel tire developed by Michelin in 2005 as a combination of tire and wheel. Airless tires are gaining attention due to advantages over pneumatic tires like puncture resistance and recyclability. The tweel uses a spoke structure and flexible resin to support weight and absorb impacts like air pressure in normal tires. Advantages include reduced maintenance, elimination of punctures, and potential fuel efficiency gains. Further research is still needed to optimize materials, patterns, and structures for airless tire design. The conclusion is that airless tires could increase safety and have environmental benefits if production costs decrease.

    DEPARTMENT OF MECHANICAL ENGG

    “AIRLESS TYRES”
    SANDEEPA CHIKKALLI
    (2GP16ME038)

    Under the Guidance of


    Mr. NARASIMHA NAIK
    Assistance Professor
    Department of Mechanical Engineering

    INTRODUCTION
    The tweel airless tyres was first developed in
    2005 by Michelin.
    The tweel name is a combination of the words
    tyre and wheel.
    since the eirler invention of airless wheel 1920s,
    the airless tyre is getting more attention due to
    its advantages over the pneumatics couter part
    Manny design studies are still needed from the
    view point of material, patterns and striuctures.

    PROPERTIES OF TYRES
    Non-skidding
    Uniform wear
    Load-carrying
    Cushioning
    Power consumption
    Tyre noise
    Balancing

    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.
    Flexing of
    spokes

    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.

    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.
    CONCLISSION
    Tyres may seem to be a trivial part of an
    automobile that cannot be improved, but
    research into airless tyres shows otherwise. This
    new technology will increase the safety of cars
    as well as have a positive impact
    environmentally. Since these tyres are also able
    to be retreaded, there is the possibility of a
    smaller cost per tyre- which is always embraced
    by the consumer. This innovative project is also
    backed and guided by engineering codes of
    ethics which will ensure that the development is
    conducted in a way that it responsible and fair.
