Non-skid pattern

In 1914, the first U.S. patent for a non-skid tyre pattern was issued to Stacy G. Carkhuff of the Firestone Rubber Co. of Akron Ohio (No. 1,093,310). The abrupt oblique edges of raised portions molded on the tyre provided against skidding in all directions. Arranged in rows diagonally across the tread surface of the tyre, the precise form of the projections was not material, but the patentee preferred to use block letters. (The image shows a sidewall area on either side of the tread area.)
