54. ZERO PRESSURE TYRE

♤ Zero pressure tires are designed to operate for a limited time with little or no air pressure without causing damage to the tire casing.

♤ Zero pressure tyres have been around for a long time, with major drawbacks such as bumpy rides and overheating.

♤ A newly developed prototype dissipates heat and has the tyre flexibility and strength to support the heavy military pick-up weight while providing a relatively smooth ride.

♤ In News: An Indian-American owned engineering firm Akron is developing zero pressure tyre for the US military, which would change the dynamics of not only war but also the auto industry. (TOI)
