Bridgestone previews Qatar MotoGP

Bridgestone is taking its medium and extra hard front and its medium and hard rear compounds to Qatar for the first MotoGP of the 2011 season. The Losail International Circuit again heralds a return to action on 20 March for motorcycle racing’s top category and for Bridgestone, which returns as the official tyre supplier to the premier class for the third year. The manufacturer says that following the Tohoku earthquake, it has pledged support for the relief and recovery of its home nation and to those affected by the events of last Friday, while “doing its best in this difficult situation to ensure that MotoGP tyre supply will be uninterrupted”.

The Qatar Grand Prix, the season’s only night race, presents unique and unusual challenges for Bridgestone’s tyres, the manufacturer says. Night-time temperatures are relatively cool at below 25 degrees Celsius, meaning that softer tyre compounds are required to generate good grip and feeling for the riders, however tyre wear is relatively high because of the nature of the tarmac. Being located in the desert outside Qatar’s capital Doha, sand blown onto the circuit makes it very abrasive, demanding harder tyre compounds in order to provide sufficient durability.
 
Bridgestone’s approach to these challenges remains unchanged from last year: medium and extra hard compound slick tyres have been selected alongside the medium and hard rear slicks to provide a balance of cool-weather performance and good wear resistance.
 
Mikio Masunaga – vice president and official member of the board, Bridgestone Corporation: “We send our deepest condolences to the people suffering from last week’s terrible Pacific Coast of Tohoku Earthquake Disaster. We sincerely hope that quality of life and a sense of normality can be restored for all those affected by this tragedy and Bridgestone group promise to help with the all-out relief and recovery effort. At this moment in the current situation we are working hard to ensure our MotoGP tyre supply is unaffected and I am confident that we will achieve this. Many Japanese manufacturers and personnel are involved in MotoGP and our thoughts and prayers are with them and their families at this time. We will continue to provide our best support to all MotoGP teams and riders throughout 2011.”
 
Hiroshi Yamada – manager, Bridgestone Motorsport Department: “This is perhaps the most publicised start to a season in recent times because of all the rider and team changes and I think we are in for a very exciting opening race and whole year. Last year our tyre allocation process worked fairly and was well supported by everyone so we will keep it the same this year, and pre-season testing has gone well so I am confident of another strong season as the Official Tyre Supplier to MotoGP in which we hope to continue playing our part in making the racing exciting and giving the riders safe and predictable tyres.”
 
Hirohide Hamashima – director, Bridgestone Motorsport Tyre Development: “The Qatar GP is a totally different challenge for us because it is the only race of the year to be run at night and in the desert. By the time the bikes are on track under the spotlights, the track temperature is around the lowest of the year in dry conditions but the desert sand often blows across the circuit. The sand is not like you’d find on a beach but more closely resembles a powder which makes the surface slippery yet very abrasive which is a difficult situation to deal with. It is very tough for our tyres as they have to be soft enough to provide grip with the low track temperature but hard enough to resist wear and graining and have sufficient strength to cope with the heavy braking points.
 
“This is the reason that we have selected the medium and extra hard compound front slick tyres for Losail instead of the usual consecutive pair of compounds. The medium compound gives good grip in the cool conditions when the track is clean, but when the track gets sandy the additional hardness of the extra hard compound provides the necessary durability and wear resistance to consistently cover race distance without graining.”
