China 2012 preview quotes: Pirelli

Tyre strategy will be at the forefront of one of the most technically demanding races of the year, as Pirelli returns to Shanghai for the Chinese Grand Prix. Last year, the top three finishers all used different strategies at a race that was not decided until the final lap and with Pirelli having closed up the performance gaps between the compounds this year, the accent on strategy will now be even stronger.

Pirelli is bringing its P Zero White medium compound and P Zero Yellow soft compound tyres to China: a circuit is well known for its fast and sweeping corners, as well as some long straights and heavy braking areas.

All these factors make tyre strategy extremely important, with a three-stop strategy having provided the pure speed needed to win the race last year. The medium and the soft tyres guarantee the best compromise between grip and performance on this circuit, but rain is a common occurrence as well, so the Cinturato Green intermediates and Cinturato Blue full wets could also make an appearance. Unlike Malaysia, where the showers tend to be short and heavy, the rain in China is frequently light but long-lasting, making it ideal territory for the intermediate.

Pirelli's motorsport director Paul Hembery: "China proved to be one of the most fascinating races in our first year, with tyre strategy at the heart of it, so we have a tough act to follow. However, the philosophy we have adopted this year actually extends the window of peak performance on the slick tyres, which means that the drivers should be able to race harder and closer. Although ambient temperatures can be quite low in China, tyre degradation is traditionally high due to the unique track layout. So although we have the same nomination as we saw in Australia medium and soft our P Zeros will face a quite different challenge next week in Shanghai."

Pirelli's test driver Jaime Alguersuari: "China is a circuit where the tyre use and strategy makes a real difference. If you want some examples, just look at last years race: Lewis Hamilton won by making one stop more than Sebastian Vettel, while Mark Webber had a bad qualifying but made good use of the tyres that he had saved to end up third."

"Two corners in particular stand out, where the tyres make a real difference: the key to getting the best of out them is to properly understand how the two different compounds behave: to begin with, the first corner, turn one. This right-hander feels like it is going on forever when you drive it and the radius gets tighter and tighter, until it turns back on itself completely. The tyres have to work really hard here in order to maintain the ideal line."

"The other key corner is turn 13: the long right-hander just before the main straight. Its a fast corner, which is slightly banked, where the tyres are increasingly loaded as you accelerate towards the straight and the DRS zone. Getting good traction out of this corner is vital particularly in qualifying so that you can carry plenty of speed onto the straight, which is crucial to your lap time."
