Limits for tire sniffer set

The GSKA spent a number of hours testing race tires with various “tire treatment” compounds as well as tire mounting compounds. The board has decided on 20ppm (parts per million) for the air inside the tire and the tire surface using the Ion Science Tiger. We feel that number will discourage anyone from using an illegal tire treatment, but still give enough margin to account for tire pickup and tire mounting products. This number may be changed at any time, with as little as 7 days notice, if the club feels that 20ppm is not an appropriate figure.
