Mercedes' run at the Pirelli tyre test was brought to a premature end on Thursday after Nico Rosbeg suffered a high-speed blowout in the morning.
The Brackley-based squad have been taking part in a three-day test at Bahrain's Sakhir Circuit since Tuesday, but things didn't go according to plan on the final day.
German Rosberg escaped unhurt after he went sliding off the track at high-speed.
"Just spun at full speed 320km/h on Bahrain straight cause my tire blew up without warning," he wrote on Twitter. "Thanks to that need to get some toilet paper now.."
The tweet was later deleted.
Very little detail has been released about the three-day test that also involved Red Bull, Ferrari and Toro Rosso, and a spokesperson told Autosport: "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."
