Grip Studs® durable ice racing studs deliver cutting edge traction for the ice racing circuit. This reliable tire stud with its unique wide–auger design installs easily with a cordless drill and stays put like no other screw–in stud on the market—no backing out like sheet metal screws. Its solid tungsten carbide shaft delivers predictable traction when you need it to help you win every time! Grip Studs® diverse auger depths work with almost any size tire, and varying prominence customize studs for driving on ice, snow or mud all season long. Grip Studs can, in some cases, be removed at the end of the season, however we recommend keeping them in and purchasing a set of warm weather tires instead. If your tires are heavily siped, find solid sections of the rubber to install Grip Studs.
