■ A m ■ wmstto? H-rsi---- . THE PLATE-GLASS TEST: This glass was pressed against a Goodrich Silvertown till the tread flattened as it would flatten against the road. Note how the centre grooves can close up when the tire is under load. See What Happens when Goodrich Silvertowns meet the road. What you see under the plate glass happens about 3DO times every minute when you drive your car. First, the tread yields as it meets the road, for balloon tires are soft. So the Goodrich Silvertown tread is flexible triple-grooved hinge-centred and it yields without distortion. Second, the weight pressing down on the tire spreads toward the outer edges of the tread——the “ shoulders.” So the Goodrich Silvertown tread has massive shoulders continuous tracks of rubber with the sharp-edged, all-direction grip of the safety blocks along the sides. Such a tread is smooth-running. It doesn't “ pile up.” Because it is undistorted, :t is free from the uneven, choppy wear which tire men call ” cupping.” By this one discovery, the hinge-centre trsad, Goodrich puts thousands of extra miles in Silvertowns. Naturally, it takes unusually inner strength to equal the life of such a tread. This strength is assured by two important processes in All the 5000 cords in these tires are stretchmatched and pressuie-fllled with rubber. Then all the rubber in every Silvertown is accurately toughened from inside and outsids both, by the Goodrich Water Cure. Goodrich Silvertowns “Best in the long run. ” FROM ALL GARAGES AND TIRE DEALERS,
