context_page_description: Ice racing is a form of racing that uses cars, motorcycles, snowmobiles, all-terrain vehicles, or other motorized vehicles. Ice racing takes place on frozen lakes or rivers, or on groomed frozen lots. As cold weather is a requirement for natural ice, it is usually found at higher latitudes in Canada, the northern United States, and in northern Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks. Tracks in North America vary from 1/4 mile long ovals to several mile-long road course designs.
context_section_description: Ice racing tires are either studded or non-studded. Studded tires have a stud such as a screw or bolt to provide better traction and increased speed. Some studs are sharpened to increase penetration.  Tires cannot be purchased with studs, so the pit crew needs to attach the studs to the tire. Through 2008, Menard's Racing in Wisconsin manufactured and sold studded racing tires for cars, and they were required in many ice-racing classes. Cars with studded tires are generally required to contain a roll cage and increased safety equipment since they achieve much more speed with the greater cornering abilities.
  The sanctioning body's rule book generally specifies the length and/or type of stud, often with the goal of controlling the level of damage done to the ice surface. Aggressive studs can cause enough damage to be a safety concern as they wear through the ice on successive laps, particularly during door-to-door auto racing.
  Non-studded tires are standard production snow tires, as used on highway-use passenger cars in colder climates. Drivers often use winter tires. Favorites among ice-racers include the Bridgestone Blizzaks and Nokian Hakkapeliittas.
