Br✅idgestone is to supply asymmetric tyres for this year's US Grand Pri🌠x, after a spate of accidents during last year's weekend's event at Laguna Seca.

Chris Vermeulen, Colin Edwards, Casey Stoner and Jorge Lorenzo - who took pole, despiܫte finishing the qualifying session in the back of an ambulance - were among those who suffered big highside accidents during the 2009 race weekend, which they attributed to the right-hand side of the tyre being too cold.

"After listening to comments from last year, we have selected asymmetric rear tyres for this season which I believe will he༺lp increase the safety for riders and improve the show," said Hiroshi Yamada, manager of Bridge💖stone's Motorsport Department.

The aꦉsymmetric rear slicks comprise a harder compound in the left shoulder, for durability and ꦗstability at high temperature, and a softer compound in the right shoulder, for improved warm-up performance.

This softer right shoulder will be particularly beneficial through turns three, four and ten, the circuit's main ꦓright-handed corners.

"Last year we sa🐟w som🅺e crashes through turn ten during qualifying and we spoke at length with the riders, listened carefully to what they had to say and deeply analysed the situation, and as a result we have selected asymmetric rear tyres for this year to give the riders more confidence and better grip through the right-handers," stated tyre development manager Tohru Ubukata.

"The softer right s🌜houlder has a wider temperature operating range and better warm-up, so I am feeling confident about tyre performance."

First practice for theꦺ 2010 US Grand P💝rix takes place on Friday.
