Grosjean complains about tire pressure
Subscriptions & booklets

M it the good results the expectations rise. 16th place is no longer good enough for fifth in the World Championship ranking. Romain Grosjean struggled with the balance of his HaasF1 Ferrari and the tires. 'The pressures are way too high. 23 PSI at the front. That is absolutely ridiculous. It drives like on ice. The car understeers, you lock the front brakes all the time. And you have no traction. There is no grip.'

Pirelli set the tire pressures at 23 PSI at the front and 20 PSI at the rear. That is 4 PSI more on the front axle than in 2015. On the rear axle, the air pressure is 2 PSI higher. 'On average, we drive pressures 21 percent higher than in the previous year,' explained one engineer. Pirelli wants to use the high pressures to prevent damage like in Spa 2015.

No new lap record in prospect

Yes Why did Pirelli announce an increase in the front pressure from 22 to 23 PSI a week before the race? Without having driven a meter. You can hear that the teams have asked for higher camber values. At 3.5 degrees at the front and 2.0 degrees at the back, they are still half a degree below the previous year.

Perhaps Pirelli was also afraid of his own courage after the fast training laps in Australia and Bahrain. Shanghai has some fast and long corners. You probably wanted to protect yourself with high air pressures.

Grosjean does not want to hear these explanations. 'The prescribed values ​​are starting pressures. That means, we hover around the track with 26 and 23 PSI. It's like in a street car.'

HaasF1 is hit particularly hard. The team has no data from the previous year, has to learn everything from scratch. At Force India, there was more glee than pity. 'It's the same for everyone. Everyone has to adjust the car so that he can handle it as well as possible.'

Pirelli takes care of it Tire pressure still down?

Pirelli sports director Paul Hembery announced that the last word has not yet been said with regard to tire pressures. 'We will analyze our data and that of the teams on Friday evening. Then we can always adjust the values.'

One thing is certain: If Pirelli insists on the pressure, there will hardly be a new record in Shanghai. Sebastian Vettel holds 1.33,706 minutes from 2011. This time you can be happywhen the pole position time of 2015 falls. It stands at 1.35.782 minutes. Kimi Raikkonen's best score on Friday was just 1,114 seconds away from that.
