Japanese Grand Prix tyre drama intensified after soft compounds failed on a resurfaced Motegi track, prompting rider Jack Miller to warn Michelin could be forced to make the hard tyre mandatory.
Soft and Medium Compounds Traced to High Degradation
During Saturday’s half‑distance sprint, Jorge Martin and Francesco Bagnaia suffered severe soft tyre wear, with Bagnaia’s rear tyre delaminating and pulling him into the pits. Martin, a Pramac rider, kept a podium place but lost a second on the last lap and lost his defense when crossing the white line at Turn 10. Marco Bezzecchi, racing the medium, reported blistering across the tyre’s centre.
Miller’s Medium Blister Report
Jack Miller, the Australian Pramac rider, opted for the medium for the sprint after preferring its stability over the soft. He described extensive blistering “in the centre of the tyre”, noting it was “not Pantok level, but not far” and predicted a hard‑tyre mandatory decision for Sunday.
Michell Hard Tyre as Potential Mandatory Choice
Michelin released new tyres at Motegi that are stiffer than last year’s version. All riders that weekend chose not to run the hard because they were “not an option” and preferred the softer compounds. However, the resurfacing might shift Michelin’s stance, prompting Miller to ask for a longer warm‑up to test the hard tyre.
Riders’ Mixed Reactions
Marc Marquez, who won the sprint, stated that the soft tyre remained viable for the race and would not force a mandatory change. Fabio Quartararo, riding the same bike as Miller, echoed that the soft compound could be chosen and expressed a preference for it if available. Only a handful of KTM riders, such as Enea Bastianini, showed no degradation issues; the rest of the field highlighted how tyre wear varied between riders and compounds.
Potential Impact on the Main Event
Given the uncertainty, tyres are suspected to turn Sunday’s race into a risky venture, especially if forced to run the hard. Miller joked about “packing up and going home” if the hard was imposed. He added, “we’ll have to try and adapt as quickly as possible tomorrow morning.” The Japanese GP’s weather forecast looks dry, meaning a wet safety‑net is unlikely.
With main‑event starts approaching, the debate over tyre safety, rider preferences, and Michelin’s option remains at the core of the upcoming race’s technical intrigue.
