After threatening to walk away from the sport if the FIA refused to increase the number of test days for Pirelli to swap to wider tyres in 2017, the World Motor Sport Council (WMSC) has given the go-ahead.
The FIA released a statement on Wednesday stating that Pirelli will be given 2013 or 2014 spec cars to run their tests and that the wider tyres will be implemented for at least the next two years.
“The World Motor Sport Council today approved changes to Articles 10.2 and 10.6 of the Formula One Sporting Regulations in order to provide the appointed tyre supplier additional opportunities to undertake testing in preparation for the 2017 season,” the FIA statement read.
“The further testing was deemed to be essential for the purpose of developing the new tyre sizes permitted by the 2017 F1 Technical Regulations.
“The changes will allow 25 car days of testing with current cars, fitted with 2017 tyre sizes, in 2016, 2017 and 2018.
“In addition, there will be an opportunity to test prototype 2017 tyres (in 2016 sizes) on 2013 or 2014 cars – these tests on older cars only apply in 2016.”
