As much as it's fun to blame the tires, you can't really do that this time.Pandabeer wrote:i didn't read all thirty pages, but i'm wondering about the pirelli tyres in 2012.

More mass true but the velocity is lower. Cornering forces would depend on m*V^2 for the same radius of curvature. So a fractional reduction in velocity will have a greater effect than same fractional increase of mass. Also Massa was being slowed down by schumacher so wasnt quite at the grip limit. Seems as if the reasoning is going both ways. Looks like we need more data .raymondu999 wrote:Webber was bottom of the qualifying speedtraps (everyone was not using DRS in qualifying) though.
Also, tyre degradation should be higher on higher fuel, because you're also moving more mass around.

If its the latter then maybe the lack of pace for Alonso can be explained. In the earlier laps the slower cornering speeds mean that the lateral forces are lower and hence less heat and less degradation. In the final laps on lighter cars and highest cornering speeds meant that Alonso degraded the tires very fast.
Also Massas pace in first stint was pretty slow while he was on par on second and third stint. Meaning that the Ferraris setup inherently was using up the softs pretty quickly while it was using the hards slightly better than the RBRs.
Another inference that might be drawn was that the Ferraris would be running a higher downforce setup (higher lateral forces: better for hards cruel on softs) than the RBRs. A quick look at the top speeds justifies the assumption. Webber 310 kph. Alonso close to 300 kph in the traps. Might be skewed a bit by DRS usage though.
There's no speedtrap in the race - just average sector speed.ankitshah wrote:More mass true but the velocity is lower. Cornering forces would depend on m*V^2 for the same radius of curvature.

Do you have the exact values from quali speed traps? cos I was looking at race data only.
True, but ahead of the race I thought Alonso's and Hamilton's strategy to do Hard-Hard-Soft would be the perfect one. My thinking (and perhaps also Ferrari's) was that towards the end of the race, the track would be more rubbered in if it remained dry, hence the soft tyre would be able to last longer, or at least postpone the graining stage. That I think proved not to be the case.Lorenzo_Bandini wrote:Easy to speak after the race but when i see Massa last stint, i think it was better for Alonso to start with the soft. Massa was faster than both RBR in the last stint, in fact, only Raikkonen and Grosjean was faster than him.

Is there a rule that prevents a driver finishing the race by going through the pits?
Why didn't, for example, Raikkonen dive into the pits on the last lap? He would've cross the finishing line before Massa, promoting him to 4th. This happens because the new Silverstone pits have this peculiarity.
The same was possible last year, so I assume there is some kind of rule preventing this...
