Bridgestone has promised to carry out a full investigation to find out why Dani Pedrosa's front tyre was in such a poor condition at the end of the Japanese Grand Prix.

Pedrosa returned to the pit lane following the race at Motegi showing visible chunks out of his front tyre, prompting Bridgestone to apologise for the isolated case.

Even so, Pedrosa enjoyed an impressive run at Motegi, finishing in third position from a lowly eleventh on the grid. His result was also achieved while he continues to recuperate from knee and arm surgery.

"We did see some problems with Dani Pedrosa's medium compound front Bridgestone tyre after the race," admitted Bridgestone race tyre manager Tohru Ubukata.

"All the other tyres that were used during the weekend, and this season, performed well so we can say this is a problem isolated to just this one tyre, but of course we have already taken the tyre to our technical centre in Tokyo where we are investigating the problem in detail.

"I would like to apologise to Dani and the Repsol Honda team, but we saw that despite the problem the front Bridgestone continued to perform until the end of the race and I am happy that Dani finished a great ride in third position."
