A new way of allocating wet-weather rubber for 2024 meant teams were reluctant to use any intermediate tyres in Suzuka’s damp FP2 session because they wanted to save them for later in the weekend.
It meant that drivers sat in garages for most of the session, with the only major running coming very late on when conditions were dry enough for slicks.
The lack of action left fans frustrated and seven-time world champion Lewis Hamilton bemoaned new regulations having triggered the situation.
“It is shame we didn't get that session,” he said about FP2. “They have changed the tyre rule, so therefore no one goes out and runs on the intermediate, which just doesn't make sense, really. But there you go.”
The situation Hamilton was referring to is tweaks made to the F1 sporting regulations over the winter that were originally aimed at increasing the allocation of rain tyres for all teams.
Instead of four sets of intermediates and two sets of full wets as they got in 2023, teams are now allowed five inters and three wets per grand prix weekend.
However, as part of the deal agreed to allow this extra set, a rule that gave teams a free set of tyres on wet Fridays was removed.
Previously, at events where there was no sprint race scheduled, if either of the two Friday practice sessions were declared wet, then an additional set of intermediates would be made available to any driver who used that compound in the session.
This effectively meant there was a free tyre set available, and it encouraged teams to run in the session because there was no downside to adding life to the inter.
