Supercars tyre pressure rule over blowouts

NZ Newswire logoNZ Newswire 23/04/2017 Ben McKay

Supercars have slapped a minimum tyre pressure on drivers at Phillip Island on Sunday, hoping to avoid another day of dangerous blowouts.

An incredible 18 blow-outs during Saturday's race prompted a review, as drivers queried the safety of the new Dunlop tyres.

Supercars chief executive James Warburton said the tyre failures could be attributed to teams operating on the margins.

"This is incredibly competitive sport and our teams will always push the limits. That is why our racing is the closest and most competitive on the planet," he said.

"We analysed and reviewed the data overnight which reveals the 13 right rear and five right front failures were subject to extremely high degrees of camber and varying tyre pressures.

"On advice from Dunlop, the Supercars Commission has today moved to mandate a minimum tyre pressure of 19psi and a recommended maximum camber range of -3 for the rear and -6 on the front."

Scott McLaughlin won his second pole position of the weekend on Sunday morning.

Once again, the Kiwi speedster lowered the lap record, setting a new benchmark of 1:29.0621 at the coastal circuit.

Saturday race winner and DJR Team Penske teammate Fabian Coulthard was second in the emerging powerhouse's second qualifying lockout of the weekend.

Jamie Whincup and Mark Winterbottom will start from the second row of the grid, while reigning champion Shane van Gisbergen could only manage eighth position.

Sunday's 250 kilometre race begins at 1:50pm AEST.
