Tire Independence NOTHER Declaration ot Independence -the motorist's independence of ^J~'J roadways, and his freedom to dare the worst of them, sure of his tires -is written broadcast by Goodrich Silvertown Cord Tires. Built on the same principle as the strongest cannon, the wire-wound big guns, Silvertown's spiral-wrapped cable-cord tire body, has the supreme resilient strength to last out roughest road travel with phenomenal mileage. Silvertowns-note the Red-Double Diamond, Red Hallmark of tire quality, on their sidewalls-mean a smarter car; comfort, economy, and road independence, which comes from knowing your tires will not break down. Silvertowns built scientifically right, have been practically proved, because SILVERTOWN CORD TIRES, along with BLACK SAFETY TREADS, proved themselves in the nation-wide road test of Goodrich's Test Car Fleets. "Mention the Geographic-It identifies you."
