pedrosa-tire-bridgestone-failure-motegi-japanBridgestone race tire manager Tohru Ubukata has issued an official apology to Dani Pedrosa and the Repsol Honda Team for the condition of Pedrosa’s front tire during the Japanese GP at Motegi. As you can see in the photo, Pedrosa came back into the pits after the race with chunks of rubber missing from the tire carcass. Bridgestone has promised to carry out a full investigation to find out why the tire was missing pieces at the the end of the Motegi GP.

According to Ubukata, no other riders or tires were affected with a similar malfunction, which makes this an unfortunate incident for Pedrosa:

“We did see some problems with Dani Pedrosa’s medium compound front Bridgestone tire after the race. All the other tires that were used during the weekend, and this season, performed well so we can say this is a problem isolated to just this one tire, but of course we have already taken the tire to our technical center in Tokyo where we are investigating the problem in detail.”

Pedrosa could very well owe his 3rd place finish to that tire malfunction, being unable to pass Rossi after several opportunities. Its a good thing the official track car of MotoGP isn’t a Ford Explorer.

Pirelli’s Cyber Tire will provide real-time tire performance information via a chip/transponder setup embedded in the tire tread. The system will send and store a myriad of information such as: operating temperature, pressure, road conditions, and vertical load. The system will work in conjunction with another Pirelli invention, the Cyber Wheel, which will convey wheel information such as hub loads in a similar fashion. While the naming is gruesome, the potential for data logging and analysis could be extremely useful to racing and enthusiasts.

Pirelli has also partnered with Brembo and Magnetti Marelli on the Cyber Tire project. While details are not certain, we’d suspect the partnership would mean a system that quickly transfers information from the tire to the driver, car, and brakes, and allows for more informed and instantaneous performance changes based on driving conditions.

The technology’s use is centered around automobiles, but the mechanics and application could easily be carried-over into motorcycles. Just don’t hold you breath on seeing it soon though. The car version is expected in 2010, with no details on whether there will be a motorcycle version. As we are all well aware, motorcycle tires already cost considerably more than car/truck tires, and last an even shorter amount of time. Presumably the decreased longevity and added costs of the Cyber Tire/Cyber Wheel system would make the technology a bit harder to justify cost-wise in a motorcycle application outside of racing.

Michelin is set to retire the tried and true track-oriented Power Race with the new Power One tire. Details are still thin, since the tire will be officially released to the world in March, but we do know that the One is the result of three years of work, more than 35,000 track laps, and will come in slick and treaded form. Michelin reports that it uses eight new technical solutions in the manufacturing of the Power one, including a new compound housing.

Expect the tire to come in three different compounds: A (soft), B (medium), and C (endurance). Slicks will be immediately available in 16,5” and in 17″ form in 2010. There is also talk of a rain and supermotard version of the tire.

Bridgestone has finally signed the agreement with Dorna Sports making it the only tire supplier for MotoGP for the next three seasons. Last season saw for Michelin dwindle as Bridgestone became the favorite shoe in the paddock, so much so that Dani Pedrosa jumped ship mid-season, leaving teammate Nicky Hayden behind who was not given the same option to switch to Bridgestone. The agreement comes about as Dorna tries to further reduce cost and make closer wheel-to-wheel racing. Continue reading for more.
