Not much has been heard from the Pirelli tyre test in Bahrain this week, despite the presence of four teams and six drivers.
However the silence was broken on the third and final day today when Nico Rosberg used Twitter to report a dramatic incident – and one apparently caused by a tyre failure.
He wrote: “Just spun at full speed 320km/h on bahrain straight cause my tyre blew up without warning. Thanks to that need to get some toilet paper now.”
However the Tweet appeared to be deleted shortly after it was posted.
We await more news from the test with some interest…

Maybe it was my reply to the tweet that did it in… LOL
“Tell us what you really think about the new tires Nico! LOL Truthfully, we are all worried! This is bad news!”
Somewhere in the Pirelli press office there will probably be an intern hastily copy and pasting the standard press release… ‘after careful investigation it was found that the tyre was not itself at fault. The problem was caused by a sharp kerb / debris on track / sharp beak of a recently deceased crow (delete as appropriate).
Thank you Nico for a well needed bit of candor.
