Voor deze ook een engelse samenvatting van dat artikel van reddit geplukt (mijn duits is slecht en kan dat altijd wel op prijs stellen)nachtnet schreef op dinsdag 28 juni 2016 @ 14:19:

Is het ook echt iets met de bandendruk? of zijn ze gewoon bezig om de remmen en banden op de juiste werktemperatuur te krijgen en houden?
Het hele verhaal komt op mij nog steeds gezocht en geforceerd over..
Maar wel interessant om te zien hoe de techniek rond de velgen/remmen en assen werkt.

- Pirelli mandates tire's start pressures higher than ever, because teams are able to reduce it when driving
- The smaller the pressure, the bigger the contact between tire and road -> more grip and more durability
- Mercedes take a tire test bench to each race to test the stiffness of the tires
- One PSI less equals one tenth of a second less per lap
- Mercedes has the best solution and their advantage is grows with higher starting pressures and air temperature
- the boosting process (heating of the tire in the blankets) is regulated (e.g. at Baku they could heat the tires for 2 hours at 80°C and 1 hour at 110 °C maximum)
- Teams control pressure using the rim; normally brake disc temperature goes into the rim and this heats the tire: The hotter the tire the bigger the pressure
- Mercedes heats the wheel carriers, the axles, the brakes to 200°C; after reaching the grid they take of the tires and cover everything with a special carbon construction and apply heated air to the brake cooling
- Ferrari and Red Bull are still very far away from that approach (with Red Bull being better)
- When the tires are fitted often the pressure grows by one psi; when pirelli is then measuring the pressure teams are allowed to deflate them.
- When the Mercedes is moving the temperature rapidly falls by about 100 °C (about 1 PSI)
- pressure does not grow when driving at the limit (more degrading, less rubber, less movement -> less heat); this applies to all teams, but with that trick a team is starting lower
- Mercedes is not scared about rule changes; maybe they already have something else up their sleeves. Force India would be happy: all the tricks cost a fortune.
