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 oan 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 300 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, it is free from the uneven, choppy wear which tire men call ** cupping.” By this one discovery, the hinge-centre t*ead. 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 Silvertown manufacture. All tbe 5000 cords in these tires are stretch matched and pressure-filled with rubber. Then all the rubber in every Silvertown is accurately toughened from inside and outsida both, by the Goodrich Water Cure.
