New Bridgestones easier to drive
10 February 2007Bridgestone completed a three day test on Thursday 8 February at the Circuito de Jerez. This test was an opportunity for teams to gain further knowledge of the medium compound dry grooved tyre Bridgestone has produced for 2007. The final day of the test, Thursday, was wet which allowed teams to run with the wet and extreme wet weather tyres.

"We have changed the working range of the tyre to make the temperature range in which the tyre operates wider," explained Kees van de Grint, head of track engineering for Bridgestone. "The overall grip level is lower, but the temperature dependency of the grip is far wider and not so extreme, which means improved driveability."
"We believe it is easier to drive and this has been seen in the testing we have had where the teams have been able to go out when it is not much above 0° Celsius and then up to 25° Celsius with the same tyre," he added. "Warm up has become less of an issue. Over the course of a season there is a lot of variation of temperature and of track surface and the wider operating window we have accounts for this. We have tested at different circuits and on different types of tarmac and have had good feedback from all of them."
