A statement describing the ban on pre-heating tyres introduced in the WEC for this season as a necessary move for the series followed criticism from drivers and team principals.
"Moving away from tyre heating was a much-needed step from a sustainability point of view and something that the FIA Endurance Commission agreed on as part of a long-term WEC tyre road map,” said Marek Nawarecki, FIA director of circuit sport.
“It is important to remember that already for a number of years there have been several motorsport series, including endurance racing series, around the world that do not rely on tyre warmers.
“The nature of every incident is different, and each case has to be looked at before any conclusions are made.”
The ban on tyre warming, which traditionally takes place in diesel-heated ovens behind each car’s pit in the WEC, was brought into focus by cold conditions over the course of the Spa 6 Hours meeting.

Toyota driver Brendon Hartley’s crash at the top of Eau Rouge on his out-lap in qualifying and Antonio Fuoco’s accident on the front straight as he left the pits after a full service were just two of the incidents in which the ban was implicated.
Criticism of prohibiting tyre warmers was widespread in the paddock over the course of the weekend.
