Lewis Hamilton crushed all hope early on at Monza by sprinting away to lead the Italian Grand Prix from start to finish. Sebastian Vettel did salvage the Ferrari fans by finished second, ahead of former Ferrari man Felipe Massa in the Williams.
Of course... I just gave this against the guy measuring it took the air out explanation.ChrisM40 wrote: I dont buy Smedleys claim that tyres cool very slowly. They are low mass, black and have a rough surface after a little use, they will cool off damn fast. If the tyres were measured at 19.5psi at 110c then yes they could easily be 1.1 psi lower after a few minutes.
From live timing, he was slower than Vettel even when in clean air. After pit stop Vettel came out just in from of Kimi and Kimi pitted 2 laps later. But in the end he finished 44 sec behind Vettel.kaller wrote:Unfortunate for Kimi to have such a bad start. He was pretty darn fast, would have been more interesting if he was battling Vettel and probably even Hamilton. Any news if it was a mechanical failure or he messed up?
Sucks for Rosberg also, for keeping the championship interesting it was not the best result really.
Feeling happy or Hamilton, he dominated the whole weekend and deserved the victory, despite the "uncool" last rounds
Also happy for Vettel to make such a important success right at home.
GP2 cars don't use tyre blankets, so I'm not sure how Mitch can complain about a test that would have been performed at ambient on his car.giantfan10 wrote:he has every right to complain about that lol....SimRacer wrote:https://twitter.com/mitchevans_/status/ ... 1465161728
But I would assume that this temperature drop needs to be in core tyre temperature and not surface temp. I still find it hard to believe (in Rosberg's case) that the core temp would drop by 20C while still being in the blankets, although they are unplugged. But maybe I'm just wrong.langwadt wrote:1.1psi ~5% low, so roughly 5% low in absolute temperature, ~20 degrees down from 110'Cpob wrote:That's to do with the maximum temperature allowed from the tyre blankets (they're not allowed to overheat the tyres).LionKing wrote:The initial report says "the thread surface temperatures of the left hand side rear tires of the cars.... was within the specification of the tire supplier" So the temperatures were in normal range when they took the measurements for the pressure.
Can someone work out exactly how much Rosberg's tyres must have dropped in temperature before the pressure was measured please?
And that fact is the very important difference. If you have no warmers then you measure the pressure when tyres are cold with calibrated device and you have a realiable measurement. In F1 either you should measure the pressure before tyres go into the warmers or tyres that are in warmers at stable temperature.Boost wrote:GP2 cars don't use tyre blankets, so I'm not sure how Mitch can complain about a test that would have been performed at ambient on his car.
Yep, I'm with you on this - do it like the fuel flow meters. Tyre pressure must never drop below a certain threshold after race start unless the race director declares changeable conditions.Just_a_fan wrote:Simple way would be to have FIA-supplied pressure sensors in the wheels. The teams already monitor temps and pressures anyway. Then it's a simple case of ensuring that, before the lights go out at the start, the tyres are at min. pressure. Drivers can warm the tyres on the formation lap to ensure they're OK. Or would that be too easy for the FIA?

That would remove one of the major car set up variables, and takes us one step closer to being a spec series. Worse even than a spec series - in most of them you can still set the car up.ChrisM40 wrote:Maybe Pirelli should just pre-fill all the tyres to a set pressure at a measured temp (say 20c) and have single use sealed valves so the teams cant adjust the pressure.
Of course you can as long it breaks the rules - like in Raikkonen's case in Abu Dhabi '13. They failed floor deflection test after missing the part on the kerb (that's your dynamic part). Did it happen? Yes. Accident? Of course but it didn't matter. Stewards can accept or ignore any explanation and apply a penalty because measurement X is out of range. Do you think they measured gains or team's guilt? Look at this:piast9 wrote:And that fact is the very important difference.

Disqualifications based on the pressure measured when tyre is out of the blankets is crazy. That is not a realiable nor reproducable measurement! If there was a rain that cooled down the slicks then everyone would be dsq based on the pressures registered by the telemetry.
You can dsq because of the wrong dimensions, shapes, weight, etc, but not a dynamically changing parameter such as the tyre pressure at unstable temperature.
'"However, the stewards did not accept that the incident referred to constituted an accident, or excused failing the relevant test."
"AUTOSPORT understands that the stewards did not accept the explanation, unlike when there was a similar situation with Romain Grosjean in Hungary, because it did not feel that the incident at Turn 3 where Raikkonen ran off the track and broke the floor should be considered as accidental damage."
"Did not feel" = interpretation. Yes, you run off track, break a floor and put the part back to cheat. It doesn't matter, hard measurement is a hard measurement."The team respects the stewards' decision," team principal Eric Boullier said. "No advantage was sought or gained in the incident and the relevant part has been replaced.
Just like with racing under yellow flags at Silverstone '13 it was OK and then Bianchi's accident happens. Soft explanation is all it takes to get away with anything - this is the issue here, there are rules with data, documents and then people come and explain and it goes out of the window. In Lotus' '13 case there was a visual evidence with car going off track. Evans is right his tyres were outside the range (reference point for penalties) and so was Mercedes'. They chose to ignore it based on a team and politics as always.
