Tire Softening Policy

Last Updated on Monday, 29 November 1999 17:00 Wednesday, 22 June 2011 14:35

Due in part to an overwhelming request from current competitors, effective July 2, 2011, the use of any tire softening agent will be strictly prohibited at Colorado National Speedway.

Each tire will now be marked at the race track when purchased with a detection agent provided by the manufacturer.  This marking must not be molested in any way after application.  The Tech Officials will also durometer all tires during pre-race tech.  All tires must fall within a margin of +/- 5 on the durometer reading compared to new tire specifications from Hoosier Tire.   In addition, markings will be randomly checked for the detection of softening agents.  If any tire fails to meet any of these criteria, penalties will be assessed as follows:

Automatic disqualification, loss of points and money earned for the night, in addition to a $1000.00 fine.

In the event of a 2nd violation the fine will become an immediate suspension, loss of all points for the year and a $2,500.00 fine.

Please note that all fines must be paid prior to competing again at Colorado National Speedway.

If you have pre-purchased tires they will need to be brought back to CNS for marking.

Thank You,
