New tyre for N.Z.
A Japanese company has developed a tyre with a built-in alarm which will sound when the tyre is punctured, and which will also permit the car to travel a further 125 miles at speeds up to 50 m.p.h. before the puncture must be repaired, or a spare wheel fitted. The Bridgestone company hopes to have the tyre on the New Zealand market within a year. The tyre is a tubeless
radial-ply type called the “Tripguard.” The puncture alarm is worked by a detector which signals any loss of pressure to a transmitter inside the wheel’s hub-cap. A receiver relays the signal to a red warning light and a buzzer on the dash. The tyre itself has a reinforced layer of rubber on the sidewalls, so that the strength of the sidewalls alone will hold the car for more than 100 miles at 50 m.p.h. For heavy cars, the tyres have a special inner tyre to help support the load when the outer tyre is punctured. The first of the new tyres to reach New Zealand will be made available to local production saloon-car drivers for testing in racing.
