Because with the barcode number and the RFID number are not the same on Hoosier tyres, the Competitor must bring all the barcode numbers of the tyres they are going to use in this Competition to the tyre supplier on site. The tyre supplier will synchronise these numbers and then give this information to the FIA. This applies to previously registered tires. If the Competitor is going to use tyres which have been purchased from Hoosier in the past but not used in the Championship, these tyres must be taken to the tyre supplier on-site so that the RFID can be checked. All Competitors must also complete the tyre registration form as before.
