Convinced they had cracked the code of the cork screw, Bridgestone arrived at the US GP with a single compound tire. Relying on data from last year’s GP, the tire manufacturer was only expecting a marginal variance in tire temperature between the left and right sides of their racing slicks. As such, they did not develop an asymetrical tire compound like they did for the Catalan GP.
As we now well know from the high-sides of Casey Stoner and Jorge Lorenzo, as well as the plethora of riders that ended up in the gravel that week, this single-compound design wasn’t up to the task of handling the track that many riders described as “one big turn”.
With eight right-hand corners, most of which are long and fast, and only five left-handers, most of which are much slower, the Circuit de Catalunya provides a worthy puzzle for all the tire manufacturers, but this weekend Bridgestone has a secret weapon up its sleeve. For the Catalan GP, Bridgestone has made a special asymmetrical tire that will be composed of different compounds on each side of the tire in order to meet the demanding conditions of the Spanish track.
The FIM has announced that MotoGP riders will have added choice for their front slick tire allocation from the end of next month. Although the total number of front slick tires permitted for a race weekend will remain unchanged at eight, three different distribution options will be made available. However, new rules on when the tires can be ordered may make the tire situation much more difficult for teams.
You may remember that a month ago, . While still able to stay in the race, fans watched as the Spainard began slowing down, unable to challenge the Fiat Yamahas any further. Pedrosa would finish 3rd for the day, but some serious questions and concerns were being asked of Bridgestone, the sole tire provider of the series.
Bridgestone has now confirmed that faulty construction of the tire allowed a foreign element to be embedded in the rubber, which later broke out, taking chunks of rubber with it.
Editor’s note: The colored rims are only for non-competetive sessions such as the Free Practice sessions, and for Qualifying or Racing.
Bridgestone, the now sole provider of tires for the MotoGP series, is taking a cue from from Formula 1 and coloring the rims of MotoGP bikes to indicate the tire compound the rider has selected. Like in Formula 1, green will be used for riders using the soft compound, and red for riders using the hard compound.
For now, this is purely for the enjoyment of TV viewers, but there is speculation that color codes could lead to abuse by teams looking to inject a little disinformation into their rival teams. We imagine safeguards similar to those in Formula 1 will be put in place, and that the coloring scheme will play into MotoGP racing as it has in the pinnacle of auto racing.
Bridgestone 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.
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.
Jeremy Burgess, the man beind behind great riders like Wayne Gardner, Mick Doohan, and Valentino Rossi has voiced his opinion about the one tire manufacturer rule for next year’s MotoGP season…just a little bit more loudly than before. Read more after the jump.
