Pirelli heads to another legendary venue in motorsport: at the Nurburgring in Germany.
Milan, July 3, 2013 – Just one week after the British Grand Prix at Silverstone, Pirelli heads to another legendary venue in motorsport: the Nurburgring in Germany. The tyre nomination is the P Zero White medium and P Zero Yellow soft: a combination not seen since the Chinese Grand Prix in April. However, Pirelli will bring Kevlar-belted rear tyres for both the medium and soft compound to Germany, which have already been tested at the Friday practice sessions in Canada. This moves comes after a series of tyre failures at last week’s British Grand Prix which, as Pirelli has now been able to establish, were caused by a combination of factors like the rear tyres mounted the wrong way around, low tyre pressures, extreme cambers and high kerbs. Even though the 2013 specification of the Pirelli Formula One tyres are completely safe when used in the correct way, the company prefers to bring Kevlar-belted rear tyres to the Nurburgring, as it is a tyre easier to manage.
Jean Alesi: “The Nurburgring is a legendary name but personally I never found the modern circuit particularly involving, although it has changed a lot during the years. It’s a circuit that tends to be quite kind to tyres, so the question of tyre management isn’t a big one: you just drive as hard as you like. There’s always been a good atmosphere though as the fans are very enthusiastic, and I am sure that is just the same now. You have quite a variety of different corners in the lap so it’s mostly a question of finding a good rhythm and stringing them together in the most efficient way. I always thought of Nurburgring as a reasonably straightforward race: it’s not so much a big challenge but more a test of precision and not making any mistakes. If you start in a good grid position and have a clean race you should come away with a good result: you don’t often see big surprises. That’s unless it rains of course: then anything can happen…”
The circuit from a tyre point of view:
Built next door to the legendary Nordschleife, the modern Nurburgring is a fast and flowing circuit that is mostly made up of medium speed corners, with a technical infield section as well. One of the big variables in the region will once more be the weather, so a versatile tyre selection is essential in order to cope with a potential wide range of temperatures.
There are a number of reasonably fast direction changes at the Nurburgring. This increases the amount of lateral energy going through the tyres and therefore heat build-up. That is the biggest reason for wear and degradation on the tyres at the Nurburgring rather traction and braking events, which are on the whole limited.
Frequent rain in the area means that the track is often more ‘green’ than other circuits, particularly at the start of the weekend, as the moisture washes away any rubber that has been deposited on the track. With more rubber laid down, grip increases and wear decreases.
With no tyre data from last year on this circuit, the work of the teams during free practice will be particularly important when it comes to assessing how the latest 2013 tyres react in different temperatures and with different fuel loads. The information gathered on Friday, which is confirmed in the final free practice session on Saturday morning, essentially decides the strategy for qualifying and the race.

Technical tyre notes:
The first corner is particularly challenging at the Nurburgring, particularly after the start where it is often the scene of accidents. Under acceleration out of it, the back of the car can step out, placing heavy demands on the rear tyres – as they need to guarantee a combination of grip and traction on one of the most technical parts of the circuit that is key to a fast lap time.
Turn seven is also particularly tricky: there is a deceleration of 5g heading into it and the front-left tyre has to do a lot of work here to compensate for the unusual camber of the circuit.
One of the keys to a quick lap is negotiating the kerbing correctly at the NGK Chicane. The drivers hit the kerbs hard, which puts a force equivalent to 800 kilogrammes through the tyre.
