Bridgestone Motorsport commenced its winter test programme this week at the Circuit de Catalunya, Spain, with each of the ten [*] teams running for three days. This week's test is the first opportunity for the teams to get to grips with the new specification tyres chosen for testing ahead of Bridgestone being sole tyre supplier for the 2007 FIA Formula One World Championship season.

Bridgestone's choice of tyres is aimed at providing a level and fair playing ground to all teams competing in Formula One. The tyres have a wider operating window than the 2006 specifications - thus enabling all the teams to access the optimum performance window. The compound range of the tyres is generally harder than those used in 2006.

Hiroshi Yasukawa, Director of Bridgestone Motorsport:

"We are delighted with the successful start to this new era of Formula One in which Bridgestone is now supplying its Potenza Formula One tyres to all teams competing in the championship. The first test has progressed well this week with the teams learning how to run the same specification of tyre. I would like to thank the Testing Committee for their efforts which have enabled this smooth transition period and the FIA [Federation Internationale de L'Automobile] for their support and advice."

As agreed by the Testing Committee two further three day tests will be conducted in 2006 at the Spanish circuit of Jerez. The official start dates for the tests are Wednesday 6 and Wednesday 13 December.
