Tire rule change affecting the Sportsman and Figure 8 divisions

Last Updated on Monday, 29 November 1999 17:00 Tuesday, 22 March 2011 08:24

Effective at the completion of the third scheduled event of the 2011 CNS schedule, (Saturday April 23rd for Sportsman and Saturday April 30th for the Figure 8 division) all competitors will be required to participate on the Hoosier 700. The Hoosier 700 has proven to be a very repeatable tire which should help to balance competitor budgets. For races scheduled prior to and including the cut off dates mentioned above, competitors will have the option to run the Hoosier F-75 or the Hoosier 700 at their discretion. In either case, all tires used for competition at CNS must be purchased from CNS.

We sincerely hope that this change will not only provide for a less expensive racing season but also provide additional opportunities for racers in the Super Stock division to purchase take off tires should that be an option for them.
