F1 teams will be able to test extra development tyres supplied by Pirelli on the Friday of race weekends.
Amendments to the Sporting Regulations agreed today by the FIA World Motor Sport Council will allow Pirelli to supply an extra specification of tyres for use on Friday only.
There had been concerns that increased tyre wear would prompt teams to do less running in practice to save their tyres. The move will also allow Pirelli to develop new tyre compounds.
An FIA statement said:
“At certain events, one additional specification of dry weather tyre may be made available to all teams for evaluation purposes. Teams will be informed about such an additional specification at least one week before the start of the relevant event. Two sets of these tyres will be allocated to each driver for use during P1 and P2, and any such tyres must be returned to the tyre supplier before the start of P3.
“One additional set of ‘prime’ specification tyres may be made available to all drivers. Teams will be informed about such an additional set at least one week before the start of the relevant event. In this instance, the additional set will be available for use during P1 and P2. One set of ‘prime’ tyres must then be returned to the tyre supplier after P1, and two further sets of ‘prime’ and one set of ‘option’ specification tyres returned before the start of P3.”
A further change to the safety car rules were also announced:
“The safety car speed limit (an approximate 40% decrease in lap time) will now be enforced over two laps instead of one. The purpose is to ensure that cars are driven at a safe speed until they reach the safety car.
“During a safety car period the pit exit light will remain green for the duration, unless the race is subsequently suspended.
“Other than when the safety car has been asked to use the pit lane, no car may enter the pits while the safety car is deployed unless it is for the purpose of changing tyres.”
The FIA also announced the Circuits Commission will “[examine] Grand Prix Circuits to identify the possibility of increasing the opportunities for overtaking.”
And they revealed a new series of measures to recognise the work of volunteer marshals including a special pit-lane visit for them: “[The]FIA and the F1 commercial promoter have agreed to permit marshals at this year’s Grand Prix to have their own pit lane walkabout as a message of thank you for their vital role.”
