A Tyre Engineer Looks Critically at Current Traction Physics



The author discusses several points in the present theory of tyre traction which he feels need critical analyzation and notes several important areas of traction physics which should present challenges to today’s research engineer:
  1. 1.

    Steady state sliding friction of tyre tread materials and energy loss concepts.

  2. 2.

    Tyres on vehicles in reference to topic 1.

  3. 3.

    Peak friction on braked wheels.

  4. 4.

    Micro and macro topographical road features and their consequences in tyre behaviour.

  5. 5.
    Tread design features.
    1. a.

      Slots, cuts, and sipes.

    2. b.

      Bulk modulus of tread rubber-trapped water globules.

    3. c.

      Three zone contact concept.

  6. 6.

    Tyre losses under torque conditions and the effective moment arm.

  7. 7.

    Tread reversion phenomena.
