Formula 1 - 'These are the worst tyres I've ever driven on in F1'

Adrian Sutil has called for Pirelli to revise its tyre compounds, after describing the current wet rubber as "the worst I have driven" in Formula 1.

Adrial Sutil of Sauber on the contentious wet tyres in Malaysia

The German failed to make it past the first segment of qualifying for Sunday's Malaysian Grand Prix, and told BBC Radio 5 Live immediately after the session that the wet Pirelli was "the worst tyre I've driven in the wet".

The Sauber driver blamed the red flag caused by Marcus Ericsson's crash for his early exit from qualifying, but said the Pirelli tyres were too hard given the amount of downforce removed from the cars by the 2014 regulations.

"Not only have we lost 20-30 per cent downforce due to the regulation, they also give us the hardest compound available," Sutil told AUTOSPORT.

"They've made the tyres harder, they've got rid of the downforce and now we have no grip. And in the rain you have no grip anyway and a bad rain tyre.

"It's all over the place. It's not only us, you can see the on-board [videos] of other cars; it's like rally driving."

Williams driver Felipe Massa agreed with Sutil's assessment and reckons Pirelli should revise its compounds.

"I don't like them as well," he told AUTOSPORT. "You go out on the first lap and it's the best, then you get slower because you lose grip.

"The degradation in the wet, the way the wet behaves, is not good."

COULD BE WORSE TO COME

McLaren's Jenson Button warned the situation could get worse when F1 leaves the heat of Malaysia and races in cooler conditions.

He also reckons high levels of torque coming from the new V6 turbo engines are exacerbating the problem.

"It's difficult when you have so much torque and you can't get tyre temperature," he said. "I don't think I've ever seen cars snapping like today before.

"I think some of it is from the power of the engine, some of it is because we're running less downforce; maybe because they haven't had so much running on the circuit for some time, with the oils, but it was unusually snappy out there.

"And it wasn't a fluid feel with the tyre - they give you false confidence in places.

"I dread to think what it's going to be like when we get to cooler climates."

NO CONSENSUS

But other drivers said they could not feel much of a difference between this season's wet tyre and last year's.

Mercedes' Nico Rosberg and Lotus driver Romain Grosjean reckon the struggles for grip are more to do with the way the engines deliver power, rather than the tyres.

"It is not such a big difference from my point of view," said Rosberg. "It is just that having more torque available, it is a bit more difficult to put the power down on the exits."

"It is one of those tracks where it is tricky and there is a lot of standing water," added Grosjean, who spun on his final lap in Q2.

"We know that they are certainly not the best of wet tyres that we have driven, but I have not felt any big difference from the past.

"We drove inters and extreme, and didn't have any big aquaplaning or anything, so they are safe."
