Tyre graining 'won't be a problem' in China

Bridgestone's director of motorsport tyre development Hirohide Hamashima say he doesn't feel there will be a repeat of the tyre issues witnessed in the season opening Australian Grand Prix as Formula One heads to China next weekend for the third round of the year.

The Shanghai event will see the second appearance this year of the super soft-spec Bridgestone tyre, which teams struggled with in Melbourne due to severe graining.

That graining saw the performance of the tyres fall away quickly at Albert Park, but Hamashima said he didn't expect a repeat in China, with the teams having more experience of working with the tyre and the Shanghai International Circuit being a full-time permanent circuit.

"In Australia there was a particular challenge of graining on the super soft tyre,” he said. “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."

Hamashima added that the circuit is one that will be hard on tyres for the competiting teams, who will need to find the ideal set-up in order to minimise tyre wear.

"Shanghai International Circuit is severe on tyres,” he said. “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.”

Lexus, what exactly has that got to do with tyres? I don't see anyone in this thread having a go at LH or anyone else for that matter. Go and rant somewhere else. To get back on topic - the fact that one set of tyres isn't optimal is the whole point of having to use the two different compounds, and is the result of a new rule for this year. The varying strategies made the end of the Melbourne race (oops, sorry Lexus for mentioning race) particularly good.
