The World's First Turnpike-Proved Tires! Pennsylvania Turnpike photo, taken at the western end of Sideling Hill Tunnel. -E -BE NE HMIAS New Turnpike-Proved Tires by Goodyear give up to 25% more mileage no matter where or how you drive... and with greater safety than ever before. BEFORE we could build these tires, Goodyear scientists had to solve two vital problems: Problem #1-tread rubber: At high speeds, ordinary tread rubber is lit erally eaten away. But through intimate mixing of new chemicals and rubber molecules, Goodyear scientists found a way to produce today's longest-wearing tread rubber for today's toughest driving conditions. GOOD Problem #2-tire cord: At high speeds, heat also weakens cord. The answer? Goodyear's new 3-T triple tempered cord (Tyrex or Nylon) with strength and heat resistance other cords do not have. Proof; On Goodyear's 140-mph test track at San Angelo, Texas, these tires proved they'll give you more safe mileage-no matter where you drive. See them at your Goodyear deal er's.
