Michelin expanded its tire allocation for the resurfaced Japanese Grand Prix at Motegi, bringing three front choices and three rear choices to a circuit where it has no testing data from the new asphalt. Michelin said the main challenge is the fresh surface across the entire track, and Piero Taramasso said the stop-and-go layout, with heavy braking and acceleration zones, puts extra stress on the tires. The company plans to use simulations and Friday practice to assess grip, abrasion and temperature behavior, with cool conditions and possible rain adding to the uncertainty.
Michelin has also added a harder-construction rear tire to its Motegi allocation as a precaution because the new surface is expected to offer more grip. The rear hard tire uses a reinforced casing previously used at the Red Bull Ring, but only the hard rear compound carries that construction this weekend. The soft and medium rear tires remain on the standard casing.
Riders have played down the harder option. Yamaha’s Jack Miller said it is “not an option,” and Honda HRC’s Luca Marini said he would prefer the softer, standard-casing tire whenever possible. Both said they would only consider the harder rear if tire degradation became severe. Marc Marquez said Ducati had trouble with the stiffer tire in Thailand and Austria, and Michelin said teams will need to adapt quickly from Friday as the track evolves.
