Shinji Aoki, manager, Bridgestone Motorsport Tyre Development Department, explains that the “rear slick tyre allocation we supplied for the Australian Grand Prix experienced extreme temperatures which affected their durability.” The race was reduced from 27 laps to 19, including an enforced pit stop at half way after Bridgestone data from practice showed the hard rear slick should do a maximum stint of 14 laps. The tyre supplier of the supporting Moto2 race Dunlop encountered similar issues, with its race also run over a reduced distance.
