France preview quotes: Bridgestone

Q. What are the challenges of the Magny Cours circuit?

KvdG: The first challenge of Magny Cours is to get there, but fortunately we have a good logistics operation to ensure this happens. Once there, we find a very interesting circuit with long fast corners, which require good stability and also slow, tight corners which is where good traction is very important, as is a rapid response to a change in direction.

Magny Cours is also a challenge for the compound of tyre as there are two distinct types of tarmac on the circuit and these have different characteristics. Two sectors have been resurfaced and are likely to be more slippery before they get rubbered in. Obviously the tyre compound has to be able to work over the entire circuit, and our predictions are that this should be the case. History also shows us that this can be one of the hottest races on the calendar so we will expect to see high tyre temperatures.

Q. What conclusions are there from the Silverstone and Jerez tests?

KvdG: First of all it has been a pretty tough week for Bridgestone, with two partner teams testing at Jerez and everyone else testing at Silverstone, and our staff flying straight back from America to be at these tests. The Jerez test was more focused on chassis developments and less on tyre evaluation. At Silverstone we had the hard and medium compounds which we plan to use for the race but due to changes in weather and mechanical issues there was not much comparison work undertaken. The hard Potenza worked well and was consistent but the medium compound seems to be the one which will be used for the main racing during the Grand Prix.
