Additional Details:
In the Firestone Factory and Exhibition Building. By this process eight extra pounds of rubber are added to every one hundred pounds of high-stretch cord, coating every fiber in every cord. This is an extra process for safety, strength and durability - not used in any other tire. Gum-dipped high-stretch cords withstand road shocks 58% longer - and the two extra gum-dipped cord plies under the tread give 56% greater bond between tread and cord body
