Where did you find that rule? The only rule I see for 1/12th is this:
Free choice of tyres. They must be black except
sidewall detailing. Wheels and tyres must not be of
a material that can damage de surface of the tr
ack. Odourless, commercially available tyre
treatment is free for as long as not suspected to be a potential health hazard and/or not
deteriorating the track surface. This to the di
scretion of the organizers who can submit for
agreement with IFMAR officials suspected additive
s in order to be forbidden for health, comfort,
safety or local legislation reasons.
