Rosberg 'in need of toilet paper' after Pirelli test tyre blow-out

Mercedes driver Nico Rosberg suffered a high-speed blow out today during the third and final day of the Pirelli test in Bahrain.

"Just spun at full speed 320km/h on [the] Bahrain straight [be]cause my tyre blew up without warning. Thanks to that need to get some toilet paper now..." he joked on Twitter, although he subsequently deleted it.

As it is a private test, no times and little other information has been released, although it is understood following the failure Mercedes ended its programme prematurely.

Mercedes were one of four teams in action at the test - along with Ferrari, Red Bull Racing and Toro Rosso - using it to sample the 2014 prototype tyres.

Pirelli meanwhile released the following statement to Sky Sports F1: "The test in Bahrain is a private tyre test, so most data generated from it are confidential. However, incidents can happen, this is what testing is for. Our testing programme will continue as planned."
