A new Technical Directive has been issued ahead of the French Grand Prix following two dramatic tyre failures at the Azerbaijan Grand Prix.
Red Bull’s Max Verstappen and Aston Martin’s Lance Stroll suffered tyre blowouts on the pit straight at Baku last time out, causing them to crash heavily into the wall.
The directive will come into effect from this weekends’ French Grand Prix at Paul Ricard with the FIA making safety being the paramount reason.
The teams will face tougher conditions over how they must operate their tyres. Pressures and temperatures will be the main focus to ensure no further failures with Pirelli rubber.
The new directive, TD003, issue C, outlines detailed operating conditions which eliminates any practices that may be used teams, with new checks being implemented. Tyre pressures are not measured real-time and the teams have been instructed to ensure that they remain within the limits that have been defined by Pirelli.
The teams have been instructed that they will be given thirty seconds to get the car onto the track after the tyre blankets have been removed. Delaying the car leaving the pits after the tyre blankets have been removed has been considered a way of making the tyres cooler, and they will now be reported to the stewards.
Any under-inflated tyres will result in the teams being told to increase their pressures which could also lead to the teams being reported to the stewards.
Tyre temperature is a key focus for the FIA with stringent checks in this area being implemented. Pressure checks during qualifying when the tyres are cold will be carried out on used tyres during qualifying.
Tyre temperatures will also be measured throughout the race weekend prior to the cars running on the track. Any teams found to have their tyres too high of a temperature will be asked make adjustments, or to have the set replaced completely.
