Michelin are to bring an additional choice of front and rear tire specifications for the German round of MotoGP at the Sachsenring. The expanded allocation is Michelin's way of dealing with the extra grip they expect the track surface to have. To cover as many situations and conditions as possible, Michelin will offer a choice of four different front tires, and four different rear tires.
The reason Michelin has opted for this approach is because they were unable to test at the Sachsenring. The circuit's location, nestled up against the town of Hohenstein-Ernstthal, means noise restrictions placed on the track made testing impossible. The circuit only has a limited number of days on which it can run vehicles as loud as a MotoGP bike, and there was no way to expand that to add additional days to allow MotoGP to test for Michelin. Given the horsepower and lean angles MotoGP bikes are capable of generating, using Superbikes or standard road bikes to test tires would not have generated the same stresses in the Michelins.
"We tried everything to have a test," Michelin boss Nicolas Goubert said. "At the end it was not possible because of the noise regulations and so on. We agreed with Dorna that we could have one more specification of tire. One more front and one more rear to cover a wider range of situations. So that’s a way to cover wider conditions."
