Great Britain GP debrief with Tohru Ubukata
Bridgestone slick compounds available:
Front: Medium, Hard.
Rear: Medium, Hard (asymmetric)
The 2010 British Grand Prix was held at the newly refurbished Silverstone circuit, returning to the venue for the first time since 1986. The teams, riders and Bridgestone had no prior MotoGP testing at the venue, making it a new challenge for everyone. Jorge Lorenzo and the Fiat Yamaha found the best solution to take a dominant victory, ahead of Repsol Honda's Andrea Dovizioso and Monster Yamaha Tech3 rider Ben Spies, who scored his first MotoGP podium finish. Whilst Lorenzo pulled away at the front, the battle for the next two steps of the podium was an intense and hard-fought battle between four riders: Dovizioso, Spies, Nicky Hayden and Casey Stoner.
Q&A with Tohru Ubukata - Manager, Bridgestone Motorcycle Tyre Development Department
What can you say about tyre performance this weekend?
"I can say that I am happy with tyre performance after this weekend as the level of grip, wear rates and consistency were all acceptable. Tyre temperatures were ok, and certainly within the operating ranges of our slicks. In the cold conditions we saw over the weekend it took some laps to warm-up the tyres to their optimum temperature, but this is to be expected of race tyres even on an abrasive circuit like Silverstone. I can say that with the softer rear it took two laps for optimum warm-up on the right shoulder, and a little longer for the left side. During the warm-up procedure, the tyres behaved more progressively though even from very cold thanks to the abrasive track surface."
What are your impressions of the new Silverstone circuit?
"Generally Silverstone is quite an abrasive circuit which generates a good level of grip. The track was dirty on Friday but cleaned throughout the weekend with every session. It is quite bumpy, and without these bumps I think that the laptimes would improve as the riders would be able to carry more corner speed in places without worrying about their bikes becoming unsettled, and this would in turn generate higher tyre temperatures and better grip."
Conditions during the weekend were cold. Were they cooler than expected?
"No, we expected the temperature to be this cool. Even on a morning when the temperature was at its lowest, it was within our expected range. We have enough Formula One experience at Silverstone to know the conditions well, so they did not come as a surprise to us."
Are you happy with the tyre compounds that you selected for this grand prix?
"Yes, I believe that we selected the best compounds for this grand prix, and that the weekend's performances proved this. There was a good performance overlap between the two compounds which meant that some riders used the softer rear and some the harder rear during the race. We invested a lot of time and conducted very detailed research to make sure we got the tyre selection right for the weekend, carefully studying the track surface character and layout, and I am satisfied that we brought the correct tyre compounds to Silverstone."
