Checks on the grid before the start revealed that his right-rear tyre tread was 27 degrees celsius above the maximum temperature allowed by Pirelli.
Massa’s exclusion promoted Lotus’s Romain Grosjean to eighth, with Toro Rosso’s Max Verstappen moving up to ninth and Venezuelan Pastor Maldonado taking the final point for Lotus.
“On the grid the tread temperature and minimum tire starting pressure of the right hand side rear tire was checked on car number 19 [Massa] after the “5-minutes” signal was given,” FIA technical delegate Jo Bauer wrote.
“The temperature measured on the tread of the right hand side rear tire of car number 19 was 137 °C, 27 °C above the maximum tread temperature of 110 °C allowed by the official tire supplier. The corresponding tire pressure at 137 °C was 20.6 psi, 0.1 psi above the minimum starting pressure.”
The stewards responded to Bauer’s referral by excluding Massa from the final results.
“The Stewards, having received a report from the Technical Delegate (document), heard from team representatives, FIA Technical Delegate and FIA Technical Assistant, have considered the following matter, determine a breach of the regulations has been committed by the competitor named below and impose the penalty referred to,” a statement said.
“The temperature of the rear right tire was measured in compliance with the FIA Technical Directive TD/029-15. The team did not comply with the FIA Formula One Technical & Sporting Regulations, FIA International Sporting Code and the instructions of the official tire supplier in the event preview.”
