Hoosier tires must be mounted with the serial code located toward the infield.
ROAD RACING TIRES:

In most cases, Hoosier tires used in Road Race applications should be mounted with the serial code toward the center of the vehicle. Once a tire has been run in the proper orientation it is acceptable to remount the tire in the opposite direction to even out the wear.
DRAG RACING TIRES, INCLUDING DOT DRAG TIRES:
(Includes catalog numbers beginning with 17, 18)
