Issue BDocument version 5 Maximum heating times and temperatures (tread & sidewall) Teams are kindly reminded that the following will be subject to FIA checks during the event: • Starting pressures • Cold pressures (according to the cold pressure cooling curves) • Re-heat pressures • EOS Camber • Maximum tyre temperatures and times in blankets • Tyre swapping • Not permitted to switch tyres from their originally allocated position. • Do not subject tyres to large deformation or heavy impact. • Do not leave fitted tyres exposed at an air temperature lower than 10°C and/or any excessive UV emission. • Revised prescriptions could be issued during the race weekend in accordance with FIA-F1-DOC-062. • Cut-off time for fitting tyres at an event on sunday morning: 4 hours prior to the race start • Heating time temperature limits apply to the actual tyre surface temperature measured with the IR gun as detailed in the FIA-F1-DOC-062. • BLANKET HEATING TIME for each temperature range to be counted from the moment the blanket control unit is set to reach its targeted temperature within its correspondent interval • Cold pressure cooling curve temperature limits apply to the average of 5 TPMS spots as detailed in FIA-F1-DOC-062.
