Bridgestone has announced that they are going to bring forward the introduction of a new 2012-spec front tire, and start allowing riders to use it starting from the Jerez round of MotoGP. The new tire was tested extensively during the pre-season, with versions tried at both Sepang tests and at the IRTA test at Jerez. The tire features a modified construction which allows it to heat up more quickly as well as provide more feedback to the riders.

The selected construction was one of two types tested during the pre-season. The two types – designated as “21” and “24” – differed only slightly, the central section being slightly less rigid in construction on the 21, when compared to the 24. The riders were positive about both types, but were split on which tire was best. The majority of the riders preferred the 21, praising it as having better stability and feedback. Surprisingly, the Honda riders took the opposite view, saying that it was the 24 which was the more stable tire, the 21 providing less stability under braking.
