Severe rear‑tire blistering in the MotoGP Japan Sprint raises concerns for tire supplier Michelin and team strategies heading into the Grand Prix
Executive summary: During the MotoGP Sprint Race at Motegi, several riders suffered severe rear‑tire blistering, with Francesco Bagnaia retiring on the final lap after his rear tire showed visible damage. The incident highlights tire performance limits under high‑load conditions, posing reputational risks for supplier Michelin and prompting teams to reassess tire pressures and compounds for the upcoming Grand Prix.
Who is involved: Francesco Bagnaia (Ducati), Jorge Martin (Aprilia), other riders experiencing blistering, Michelin as the official tire supplier, and the competing MotoGP teams.
Likely next: Teams will analyze post‑race tire data, potentially adjust pressures or select different compounds, and Michelin may issue a technical bulletin ahead of the Motegi Grand Prix.
