The first US patent for a non-skid tire 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 tire prevented against skidding in all directions. Arranged in rows diagonally across the tread surface of the tire, the precise form of the projections was not material, but the patentee preferred to use block letters.
