For the Competitor entered in the Series who has not taken part in a single start with slick tyres ( because of wet track for instance ), the permission will be carried over to the following Event. However if the Competitor finishes a race with slick tyres, those tyres will become used tyres for the next race, for which the Competitor can use only one set of fresh slick tyres.

After this the damaged tyre must be taken to Michelin tyre expert for inspection. All other deflated slick tyres on their wheel rim must be provided to Michelin tyre expert for inspection, in order to find the leaking spot. In case the wheel rim is causing the leak, the wheel will be repaired or the tyre installed on a new rim, the leaking rim does not authorize use of new tyre. 13) During the race a new slick tyre is authorized to be replaced by another new one in case it has not been used for one entire race.

The serial number of the replacement tyre must be recorded in the follow up form by the scrutineer. 14) In case a new slick tyre has been taken to replace a tyre belonging to used tyres set during a race, the new tyres set can be completed by replacing the tyre used during the race, with another new one for that set.
