LIFE OF A TYRE-TESTER
EXHAUSTIVE EXPERIMENTS Driving, driving, always driving. Two hundred miles to-day, three hundred to-morrow. A rest, if ho is lucky, on Sunday. That is the life of Mr. J. Petherick, who tests tyres for the Dunlop Rubber Company over Australian roads. The only place to test them is on every conceivable variety of road, so Mr. Petherick wanders over mountains and across streams, hits up to 70 on straight hard thoroughfares, and clambers and scrapes over ruts and rocks. He has driven his Panliard-Levas-seur nearly 100,000 miles, fitted with half a dozen different sizes in tyres, and wheels, and a hundred different compounds and mixtures of rubber in the tyres. Mileage achieved by each tyre is carefully cheeked, and the lasting qualities of the various compounds discovered. The best record for a tyre, to date, is 15,000 miles; but Mr. Petherick says that new experiments are showing better results all the time.
