Bridgestone have added two new tires to their 2015 allocation, in response to developments in 2014. A new extra-hard rear will be made available at a few of the more abrasive circuits on the calendar, while the asymmetric front, debuted at Phillip Island last year, will also be available at more tracks.
Two new tires means two new color codings, to distinguish them from the existing allocation of tires. The extra hard rear will carry a yellow stripe around the side, while the asymmetric front will be indentifiable by a light blue band on the sidewall.
The existing color codings for the remainder of the tires remain unchanged, as shown in the tire chart and table below.
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. Source:
