Formula 1 teams have voted against returning to 2018-spec Pirelli tyres following a vote on Friday in Austria.
Red Bull and Ferrari had been pushing for a return to last year's tyres, which featured a thicker tread depth, but during a vote on Friday it was reportedly split 50:50 with five teams voting in favour and five against – a majority of seven was required for the FIA to consider the switch back.
Last year F1's sole tyre supplier Pirelli reduced the tread depth by 0.4 millimetres to combat overheating at certain races. This change was carried through to 2019 and some teams believe it has unfairly benefitted Mercedes.
The push to return to 2018 tyres has been ongoing but on Friday it was put to a vote during a wider meeting to discuss the future of the sport.
All ten team bosses were present, as well as Ross Brawn, FIA technical boss Nikolas Tombazis and Pirelli's Mario Isola. Driver representatives included Lewis Hamilton, Sebastian Vettel, Romain Grosjean and Charles Leclerc, plus GPDA chairman Alex Wurz.
According to paddock reports, the five teams that voted against the switch were Mercedes and its customer teams Racing Point and Williams, plus Renault and McLaren.
With a majority voting against the proposal, the tyres will remain the same for the remainder of the 2019 season, although it's believed a proposal was also put forward to allow teams to test Pirelli's 2020 tyres during Friday practice at select events, which is due to be considered by the FIA and Pirelli.
