Description
Three color 9 1/2″ x 13″ ad for their General Dual 90 tires. The picture shows one of these tires standing up against a red background with a series of three white rings across the page. It is explained that “These 3 rings instantly identify the most amazing tire you can buy!” and the text claims improved safety and mileage. It gives much of the credit to the fact they are made with Nygen cord and being made from Duragen rubber which allows it to seal itself in the event of a puncture.
