From this weekend’s ninth round of the 2023 season onwards, riders must run to the minimum tyre pressures for the front and rear compounds in the sprint race and the grand prix.
The front minimum is 1.9 bar, while the rear minimum is 1.7 bar.
This rule has been in place since the start of the year, but will only be officially regulated from this weekend’s British GP – with riders expressing concerns about this on Thursday.
Michelin motorsport boss Piero Taramasso has clarified to MotoGP’s world feed how the rule will be monitored, with riders being selected at random after each race to have their pressures checked.
“So, this is just the official legislation,” he began. “Until now, everyone was just working to the same value of minimum pressure but was not monitored by Race Direction.
“So, now everything is monitored by Race Direction. After the sprint and after the race on Sunday, there will be some random checks of some bikes to check if they respect the minimum tyre pressure.
“That means they have to run half of the race [in the grand prix] at the minimum pressure. For the sprint it’s only 30%. Then they can run lower for the rest of the race.”
