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. ■ 4 4 when Goodrich Siivertowns 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 arc 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 of the tread—the " shoulders." So the Goodrich Siilvertown tread has mansive shoulders—continuous tracks of *ubb«ir —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 tread, Goodrich puts thousands of excra miles in Siivertowns. 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 the 5000 cords in these tires are stretchmatched and pressure-filled with rubber. Then all the rubber in every Silvertown is accurately toughened from inside and outside both, by the Goodrich Water Cure. "Best in the ff FROM ALL GARAGES AND TIRE DEALERS.

TAaf %/ier compression POWER paid for in i 926-27-28 cars demands a petrol designed for it. m vOk Many cars of 1926-27, and still more cars of 1927-28, amply cannot aive you their best results on the petrols found efficient in former years. Why? Because compression ratios are higher and piston speeds are different. A different petrol with a different way of acting is required if you are to get maximum results. The results you wish for are ease and mastery in the new set oi traffic regulations and conditions that you face. 1 o get these results, Mil up with TEXACO MOTOR SPIRIT. Power, pickup and hill work are at once improved. Open road time trom point: to point is cut down.
