Russell’s car was accidentally fitted the front two midrange with a set of Bottas tires at the Sakhir Grand Prix earlier this month when it appeared for Mercedes.
Mercedes brought Russell in the next round to put him back on a set of his own tires, but sparked an investigation from the stewards for shuffling sets of tires.
Mercedes was fined € 20,000 for the incident after flight attendants admitted there were extenuating circumstances – the team cited a radio issue – and decided to correct the error as quickly as possible.
But the stewards in their report called for the FIA to adjust sporting regulations to take account of such an incident, which was unprecedented in F1.
In the latest edition of the F1 Sporting Regulations published following the World Motorsport Council meeting this week, clarifications have been made to the rules for tire use.
The updated rule reads: “Any driver who uses a set of tires of different specifications or tires not assigned to him during the race may not cross the line on the track more than twice before returning to the races. stands and change them to a set of tires of the same specification. ”
There was previously no clarity for incidents where a driver used tires assigned to another car, putting Russell at risk of disqualification.
The regulations still state that any driver who does not change the tires within three laps will be assessed a stop / go penalty of 10 seconds.
Another tire regulation change in the sporting regulations is confirmation that Pirelli will continue to supply a standard amount of tires to teams for each race, moving away from the custom selections that were previously offered before 2020.
The teams will receive two sets of hards, three mediums and eight softs per race weekend.
The updated regulations also reduce the maximum race time, including red flags, from four hours to three hours, and increase the number of races allowed in the championship to 23 to reflect the approved schedule for next year.
