F1 Teams will learn about Tyres - Bridgestone
Hirohide Hamashim, Bridgestone's director of motorsport tyre development, is confident there won't be a repeat of the tyre confusion which occurred at the Australian Grand Prix as Formula One prepares for the Chinese Grand Prix next weekend.
The super soft-spec Bridgestone tyre, which caused issues for teams in Melbourne due to severe graining causing reduce performance quicker than expected, will make its second appearance at Shanghai. Hamashima said "In Australia there was a particular challenge of graining on the super soft tyre...However this graining varied across the teams between the front and the rear, which means that the correct compromise set- up for these new cars is still being found...For this reason we would expect less graining in China as the teams now have better understanding of their cars than at the first race. Also, Shanghai is a permanent race track so the track surface should be better."
However he did add that "Shanghai International Circuit is severe on tyres...There are very high lateral forces and we expect to see graining on the front left tyres, especially caused by the increasing radius turn two and the banked turn 13. We could also see graining on the rear tyres here too."
"The circuit layout means that a medium downforce set-up will be used, as there are two long straights, but a large percentage of the track is also very twisty and technical. For the teams and drivers, finding the correct set-up to make the best use of their tyres will be a big challenge."
