National Geographic : 1939 Apr
As the air tire literally THIS year being the Hundredth Anniversary of Rubber, we naturally wanted to make it memorable to every tire user. And after turning everything up side-down we contrived new stuff in tire engineering that makes our Centennial tire--the new "G-100" All-Weather-an all round standout. Now you know that in cross section an ordinary tire is round. When inflated it e-x-p-a -n-d-s equally, stretching the tread. And when stretched, rubber cuts and scuffs more easily. But you'll note that our new "G-100" is elliptical-ovalin cross section, higher than wide. As air goes in it actually contracts ver tically -firms down instead of "growing." This action compressesthe tread literally "makes amuscle"-mak ing it tougher to cut, harder to scuff, making it wear 33% longer! Dotted outline shows shape of tires before inflation; solid section after. Note how the new "G-100" actually compacts in overall diameter-firms down-compressing thetreadto make it more resistant to cuts and wear. And beyond this, "G-100" All Weather gives you 11% more rubber on the road for greater grip, surer traction. It has more durable cords in the sidewalls a sturdier low-stretch cord that marks a new high in resistance to bruising and blowouts. A handsome performer, it is equally handsome in its sleek sculptured lines that match the streamlining of modern cars. You want the best for your money, so go see this great Centennial "G-100" tire at your Goodyear dealer's-he has it in stock now. One Hundred Years ago Charles Goodyear discovered vulcanization and made the modern rubber in dustry possible.
