V8 Supercars has increased the minimum permissible tyre pressures for today’s final race at Pukekohe following Craig Lowndes’ spectacular failure on Saturday.
The rule has been increased from a 17psi minimum to 18psi as a response to the failure, while the category has also mandated that cars must start on the soft rubber.
Teams must remove the tyres at the first pitstop, which must take place no earlier than lap six, and are not allowed to reuse them later in the race.
This weekend marks the first time the softs have been used at Pukekohe, adding to the uncertainty over how they will perform during today’s 200km journey.
“We want to ensure that the competitors can race fairly and equally and put on a good show,” said category technical manager David Stuart.
“In consultation with team members in pitlane, we’ve put measures in place.
“What we’re going to do is have every competitor start the race on the soft tyre.
“We’ve done a complete audit of car set-up and looked at the tyres from yesterday.
“We’ve put a recommendation in place for rear cambers in particular and also increased the minimum tyre pressure by 1psi to 18psi.”
