2010 PKC Rain Tire Rule
Tuesday, 19 January 2010 18:42
The official rain tires for 2010 PKC NorCal and SoCal events will be Bridgestone YJP or YKP; no other rain tire may be used.  These tires were chosen due to wide use and availability.  If such tires are used during a competition session they will be marked by the technical officials at the end of the session and will be the only set of rain tires the competitor may use.  Note that either new or previously used rain tires may be utilized.
