Identifying tires has always been something of a dark art. Ever since MotoGP went to a single tire supplier, identifying which tire a particular rider is on and when has become ever more important. Fast laps mean a lot less when a rider sets them on soft rubber.
So far, identification has been done visually, by colored stripes painted on the sidewall of the tire. That worked fine when Bridgestone was still the tire supplier as the colors they used – red, white, plain, and green – based on their corporate colors were easy to spot, and applied in a big thick stripe.
It got more difficult with Michelin, as their corporate colors – blue, white, and yellow – are more difficult to spot from the side of the track. Journalists and fans were mostly reliant on the eagle eye of Dylan Gray, pitlane reporter for MotoGP.com, to spot who was going out on what and when.
Identification is to become a lot easier in 2017, with the introduction of an automatic identification system. At the Sepang test, Michelin boss Nicolas Goubert explained how the system will work.
