The Bridgestone press office released the following question and answer session with their Director of Motorsport Tire Development, Hirohide Hamashima:
Spanish Grand Prix debrief with Hirohide Hamashima
Round 2: Spanish GP – Post-race debrief
Jerez Circuit, Thursday 7 April 2011
Bridgestone slick compounds available: Front: Medium, Hard. Rear: Soft, Medium
Bridgestone wet compounds available: Front: Soft. Rear: Soft
The Spanish Grand Prix started with the bright sun and fine weather the Andalucían venue is known for, but on Sunday the rain arrived and the first European GP of the season was also the first wet race since the Malaysian GP in 2009. Early on in the weekend the laptimes were very fast and several riders dipped under the lap record. The race however started wet so every rider used Bridgestone's wet tyres for the first time since the Portuguese GP last year, but as the track started drying by the end of the race the conditions became very tricky. The race was punctuated with crashes with several of the front-runners falling, handing Jorge Lorenzo a dramatic victory ahead of Dani Pedrosa and Nicky Hayden.
