Mercedes and Red Bull continue to subvert the minimum tire pressure rules and are now thought to be joined by Force India and Torro Rosso. To maintain safety Pirelli have been continuously increasing the min tire pressures putting the other teams under more difficulty with their tire performance operating windows.

"they give certain teams in the final qualifying round more grip and the tires in the race a longer life. Who out the trick, quickly gaining a few tenths and lap time in the race has the wear better under control. In suspected of Mercedes , Red Bull, Force India and Toro Rosso."

If Mercedes are gaining 'a few tenths' then Vettel should have been on pole today in Canada. Also it was obvious that the Ferraris needed 2 to 3 laps on the higher pressures to get heat into their tires, clearly a big disadvantage to the teams following the rules.

"The FIA ​​has tapped the tire pressures of the moving car in real time in Monte Carlo. And found what we already knew of samples from the data analysis. Some teams are short for a qualifying round to reduce able the air pressures of the tires falls below the predetermined Pirelli Start pressure and keep it later in the long term at the minimum value. Normally, the tire pressure should however rise by 1.5 PSI over the start value by the heating while driving. Without the cooling phase in between."

"In principle, the teams, the brakes and thus the wheel preheat so strong that when attaching the wheel increases the tire pressure on the heat transfer through the rim. And that is the moment in which the FIA ​​Commissioner measures air pressure."

Mercedes though may have tricked themselves in Monaco with their 'fins' cooling Rosberg's tire too much and ruining his race. Canada is set for a cold race day so will Mercedes catch themselves out again?

New rules may be implemented by Austria changing the tire testing procedure to avoid Mercedes et al from running dangerous tire pressures.

" to prevent the artificial heating of the tire when mounted one way. One could already measure the initial pressure when the tire is not yet mounted. Who then puts it on a preheated wheel, harms himself, because he the pressure can not be corrected afterwards. This regulation could already come into force at the next race in Austria."

At the time of the test the pressures meet spec. They use pre-heated hubs and brakes to increase the pressures artificially and then have fins in the wheels reject this heat quickly once on track to bring the pressures down before the quick Q lap or the start of the race. There is no way to practicably or reliably test when they are on track so they have been getting away with it.

The FIA should insist that real time tire pressure telemetry is sent to them, we know that tire pressures can be monitored remotely, the FIA get other telemetry, so why not tire pressures?

They said that there were too many issues with the sensors, calibration etc.
#440424
In that case, maybe the FIA need to have standardized wheels and tires provided by an independent third party to stop custom wheel designs from altering tire pressures. Either that or do away with minimum tire pressures, making it clear that if teams have a blowout due to low tire pressures, all liability for damage or injury will fall upon the team, not Pirelli or the FIA.

Here is a close up picture of Merc tire pressure trickery in Baku. Pretty blatant.

Heater set to 200C!

I believe new rules were in place for the Austrian Grand Prix; I kept on hearing commentators mention cars having to run higher pressures during the race.

OK... but, what was done about the "allegations"?
Were they investigated? Was a decision reached?
