Pirelli made a minor change to the minimum tire pressure limits ahead of final Formula 1 practice for European Grand Prix in Baku.
Romain Grosjean said he hoped Pirelli would review the rear pressure while Lewis Hamilton said the pressure was “ridiculous.” Pirelli chose to investigate the data overnight and found that the limit was a too conservative.
As a result, the tire supplier has decided lower the rear tire pressure by one psi to 21. The front will remain at 22psi. That will remain the case for FP3 and qualifying before further analysis will be undertaken.
If there are no issues with integrity as a result of the change, it will remain in place for the race.
