The new Tire Pressure Monitoring System (TPMS), introduced this season in MotoGP, will remain in testing and therefore without penalties until the Italian GP, at least.
MotoGP and the FIM have announced for the 2023 season the harmonization of the tire pressure monitoring and control system for all riders participating in the premier category of the World Championship. The system was concretely put in place from pre-season and from the first weekend of the season, in Portimão.
Initially, however, the international federation and the IRTA, the teams’ association, decided that the first three races of the season, that is to say until the Grand Prix of the Americas, would serve as a full-scale test to refine this device and ensure that the measurements are correct.
The Spanish Grand Prix, which takes place this weekend in Jerez, was therefore to be the first where penalties would be imposed if a driver does not respect the parameters set by Michelin in terms of minimum pressure of the front tires.

However, according to information from Motorsport.comthe system will remain in the testing phase throughout the weekend and next Monday’s practice in Jerez, but also during the French Grand Prix, and should be fully operational from the Italian GP in early June.
This new TPMS system (Tire Pressure Monitoring System, or “tire pressure control system”), consisting of a sensor that measures tire pressure in real time and transmits it to Race Management, has been used since the pre-season. If it works correctly for the moment, the officials believe that it still needs a little time to perfect it and avoid any error when penalizing the pilots.
The minimum and maximum pressures, set by Michelin at each Grand Prix depending on the conditions, will be between 1.88 and 1.90 bar, a level below which no driver will be authorized to complete more than half of the laps in the race. .
This measure has been included in the MotoGP 2023 regulations, and riders who break the rule will be sanctioned. According to FIM data, if the rule had been in force for the first three Grands Prix of the season, no driver would have been penalised.
This pressure control is causing some concern among pilots. Some have deemed the limit set by Michelin too high, especially since the pressure is likely to increase when a driver is in the slipstream of a competitor. Too high pressure reduces grip and can make the bike difficult to control, but Michelin fears too low pressures which might degrade the tyres.
