Bridgestone tests new marking system at Sepang
Bridgestone tested two new marking systems on their 'option' tyre today at the Sepang International Circuit as testing kicked off. The first system is a large red circle on the outside of the tyre and the second is to have a white line sprayed on the bottom of the outside groove of the tyre, which is visible from the front. Both systems were tested by Williams driver Wurz.
