Red Bull RB7 - tyre warming strategy 08 October 2011

Red Bull have devised a clever way to maintain tyre temperatures in the garage. The FIA long ago banned systems designed to do this by heating the inside of the wheel rim, as introduced by Toyota in Canada 2005. Since Belgium this year, however, Red Bull have been placing a small, pre-heated aluminium cylinder (right) inside all four brake ducts, an idea tested by Williams some years ago. The cylinder's primary function is to heat up the brake discs, but it also stops cold discs and callipers from robbing the blanketed tyres of valuable temperature. Just before the car leaves the garage mechanics wearing special gloves remove the rudimentary brake duct covers (left) and take out the cylinders.
