Tyre management vital at 2012 F1 GP of Japan

Mark Webber Red Bull RB8

The 2012 Japanese Grand Prix puts the biggest energy loadings through the tyres all year, with the two P Zero compounds that have been nominated for Suzuka – P Zero Silver hard and P Zero Yellow soft – taking to the track for the first time during the two free practice sessions today.

McLaren driver Jenson Button, the winner in Japan last year, went fastest in the first session with a time of 1m34.507s: two-tenths of a second quicker than his team mate Lewis Hamilton. Button used the hard tyre to set his time with half an hour of the session to go, displacing Red Bull’s Mark Webber, who had been fastest earlier in the session with the hard tyre as well, used exclusively by all the drivers in the morning.

As usual, the drivers sampled the soft tyre for the first time in the afternoon, with track temperatures close to 40 degrees centigrade. Caterham’s Vitaly Petrov was the first driver to try the Yellow compound after half an hour of the second session. Button subsequently went quickest on his first run with the soft tyre, but the fastest time of the session and also the weekend so far was established by Webber with a benchmark of 1m32.493s on the P Zero Yellow after an hour of running. The final 30 minutes of the second session were largely devoted to long fuel runs by the majority of the teams, on a circuit where understanding the degradation is vital.

The first half of the lap at Suzuka is essentially a series of non-stop corners, which brings the tyres rapidly up to temperature but also means that the compound is constantly working with no chance to cool down. There is some new asphalt laid last year for the second half of the lap, which consists mostly of high-speed, wide radius corners, but as is often the case the whole circuit was ‘green’ and slippery at the start of free practice, before some rubber was laid down on the racing line.

Pirelli numbers of the day:
Sets used overall:
Hard: 48
Soft: 23
Highest number of laps per compound:
Hard: 917
Soft: 314
Longest runs per compound:
Hard: 17 (Glock)
Soft: 19 (Kovalainen)

Pirelli facts of the day:
Suzuka is one of the most selective circuits of the year: since 2003, only drivers who are world champions have won.
In seven out of the last 10 grands prix at Suzuka, the man on pole position has gone on to win the race.

Such is the normal pace of the action that 19 cars completed the 53-lap race on the lead lap last year – Pirelli’s first season in Formula One – establishing a record for the highest number of cars to finish the race on the same lap as the winner.
