One complaint has consistently run through the past couple of MotoGP seasons, it has been the pressure of the front tire. Pick just about any race and you will find riders saying that rising pressures and therefore (Boyle's Law) temperatures of the front tire cost them a better result. At Jerez, for example, Fabio Quartararo had been unable to do much more than follow Pecco Bagnaia home because every time he got into the Italian's slipstream, the temperature of the front tire would rise, as would the pressure, making it impossible form him to outbrake the Ducati.
At Motegi, it was Bagnaia who was struggling with increased front pressure as he followed Quartararo around, eventually contributing to his crash. Enea Bastianini had similar issues that race. In Aragon, where Quartararo had real trouble in 2021, the Yamaha rider was planning his tire pressure around his starting position, not that it ended up mattering much after he crashed into the back of Marc Marquez.
