Bridgestone try out new tyre markings 27 Mar 2007
Formula One tyre suppliers Bridgestone have used the opening day of the Sepang test in Malaysia to evaluate alternative ways of visually differentiating tyre compounds. Williams Alex Wurz ran with tyres featuring a large red dot on the sidewall and a continuous white line painted within one of the grooves.
2007 regulations require Bridgestone to supply teams with two compounds at each Grand Prix and every driver must use both compounds during the race. At the opening round in Australia, a small white dot on the sidewall was used to differentiate the compounds.
However, many felt this was too difficult to spot, with fans only able to see which compound was being used when cars were at a standstill in the pits.
