Michelin explain Friday tyre problems 02 Apr 2004
Michelin have said that detached drainage hatches at the Bahrain circuit were the likely cause of deflating tyres for David Coulthard, Fernando Alonso and Anthony Davidson on Friday.
Three of our drivers suffered damaged tyres during the course of todays free practice, said Pascal Vasselon, the French companys F1 programme manager. "We have found identical marks on all three affected tyres and they all suffered kerb impact damage prior to deflating.
Michelin has collaborated with the FIAs technical department in order to establish what caused three of its tyres to sustain damage during todays second free practice session. An inspection of the track has revealed that two drainage hatches have become detached from their concrete bases, creating sharp ridges that will damage any tyre that crosses them.
A temporary cure has been set up for todays remaining track activities and a permanent solution will be in place before F1 practice resumes tomorrow morning.
Davidson and Alonso got their cars back to the pits, while Coulthard spun off into the gravel in the closing minutes of Practice Two.
