Nico Rosberg continued to top the timesheet in the second practice session of the Belgian Grand Prix, during the mid-part of FP2 German lost control of his Mercedes when the right rear tyre break up at around 320 kph at the Blanchimont corner.
The session was red flagged and suspended while the car and debris were cleared from the spectacular and majestic, but challenging, circuit in the Ardennes forests.
Pirelli have launched an investigation into the apparent tyre failure which triggered Rosberg’s high-speed crash during FP2 for the Belgian GP.
“We’re investigating exactly what happened with Nico Rosberg’s tyre,” confirmed Pirelli.
Mercedes F1 team technical director Paddy Lowe says he’s never seen anything like Nico Rosberg’s FP2 tyre blowout but insists its “too soon” to say there is a safety concern with Pirelli’s tyres in Belgium.
“There’s different bits of video showing some sort of unravelling up to a minute before the actual catastrophic failure,” Lowe told Sky Sports. “The big question will be what’s initiated that.”
When the source, asked what could have initiated that failure, Lowe replied: “I don’t know, I’ve never seen anything like that before. We simply don’t know, we’ll have to wait. We’ll obviously take the tyre away and make sure the car wasn’t a contributor to it in some way.
“[I’ve not seen it] in a way where it has started to unravel. I don’t know whether you’ve ever seen a video like that … Normally these tyres seem to build up much more quickly.”
