Overview
- Jack Miller said he felt “quite embarrassed” after his pace collapsed at the Austrian Grand Prix when his lap times fell from the low 1m32s to a final 1m40.225s as the rear tyre shredded.
- Miller and other Yamaha riders reported a wide strip of “base rubber” on the rear tyre that led to heavy wheelspin and lap‑time losses in the closing laps of Sunday’s race.
- Miller said Yamaha suffered electronics problems all weekend that prevented smooth power delivery and made the tyre’s centre wear far worse when the bike was loaded or picked up.
- Michelin had fitted a stiffer rear carcass at Spielberg, a construction used selectively at high‑energy tracks, and teams will now analyse how that casing interacted with different bike electronics and chassis setups.
- Yamaha’s four riders finished near the back of the field and the team says the findings from this probe will be important ahead of Motegi, which uses standard tyres, and Mandalika, which may reintroduce the same casing.
