Tianyee Tire Company develops leak-proof tyre

(Rubber Asia) Shanghai Tianyee Tire has effected a revolution in leak-proof tyre technology by developing the Tianyee Tyre, a Chinese version of safety tyre which can replace run-flats.

The technology involved is characterised by a 2-3 mm thick layer of synthetic rubber, known as memory polymer, coated on the inside wall of an ordinary tyre. Once a foreign object pierces the tyre, the memory polymer coating will envelop it entirely so that the tyre will not leak. When the foreign object is removed from the tyre, the memory polymer coating will automatically block the hole. As a semi-solid layer, the memory polymer coating helps the punctured tyre remain leak-proof at 20- 100 ° C. Shanghai Tianyee Tire recently showed off the unique properties of the tyre at the 4th China International Automobile & Modified Car Show.
