Has it happened before that the FIA is actually enforcing the paramaters in which the teams can operate the tires?

Its Pirelli, via FIA so its enforced.

[kaller]

I know that. Maybe I worded it wrong - I want to know if this has happened before the Pirelli incident in the past?

I ain't buying their uni-directional explaination.
IF it had to do with counter rotating the bands then millions of road tires would be doing it as well. Think about the construction and the way most road tires are rotated.
What makes the tire uni-directional is the tread, of which F1 tires have none.

The Matchett explanation on US coverage sounded persuasive, but it made me wonder how it is possible to make a non-asymmetric tire. The only option, if I understood the explanation,is to have the belt exactly equal the diameter, so there is no overlap and hence the tire can rotate either way without unraveling. This seems unlikely to me.

I think the majority of the tire problems this season have been due to three things. (1) Pirelli unnecessarily changed the tires from what was in place at the end of 2012, (2) Pirelli did not have the integrity to admit a safety concern, and (3) the FiA did not have the stones to declare a safety concern by fiat.

I found it interesting that Alonso changed his position on the YDT completely. Initially he said he would refuse to drive. Now he says there is opportunity to develop and it is worth to go for him to drive.
This seems to indicate that driving the 2013 hybrids (2012 carcass & 2013 compounds) will substantially push Ferrari's development program.
In the light of this races result it appears to me that the IT's punishment to Mercedes just got unproportionally increased in terms of sporting equity.

I think..That the teams got carried away with low pressure, possibly down to 8 lbs cold, and too much camber causing too much flexing and inherent heat build up.

[WhiteBlue]

Are you talking the German GP or the British, Strad? The tyre parameters were controlled for this race. And in the last race we had tyres fail on the McLaren which was run 100% within Pirelli's parameters, which kind of defeats the idea that pressure and camber were the big deal they are made to look by Pirelli. All these things probably had their little influence but in the end you had big factors like massive increase in cornering forces and dynamic issues combined with a carcass that had to sustain more heat generation, storage and loads than it could. It sounds unreasonable to me that Pirelli effed up on small things that they should be capable to calculate. It sounds more reasonable that they got caught out by things that you cannot easily simulate. Greatings from Indianapolis 2005. Tyre makers should learn from each other's mistakes. But the secrecy in that business probably means they all have to have their Indy or Silverstone to understand the problems. It is a petty that drivers have to be the guinea pigs for that learning process.

Silverstone WB
What makes you think McLaren didn't run their tires soft?
What makes you think that prior to Germany that they told them what pressures to run?
I know that in NASCAR they are often told by the tire reps what pressures and temps etc might be desirable, but I am not aware that Pirelli in the past, told the teams what pressures to run.

It is all in the thread. Sam Michael and Martin Whitmarsh told the press that at all times McLaren ran the specified pressures and cambers required by Pirelli. Nevertheless they had a blowout in the race and one in practice. This press conference happened after Pirelli accused the teams of running outside the parameters. Only after that little war of words Pirelli admitted that they specifically allowed McLaren to swap the tyres because they had no concerns prior to Silverstone. Qed

Mercedes hopes to win F1 young driver test reprieve from FIA.

haha, smooth.

Doesn't hurt to ask does it

[WhiteBlue]

The reports calls it unlikely that Merc will be allowed to test quoting Ross Brawn because only if a fourth day is attached would there be a point. Generally I have to say that I'm a bit disappointed with the way the tyre testing is going to be handled. The next two private tests will be done with an old Pirelli car which is clearly inadequate. The young drivers test is not optimized for development because it will primarily address the performance testing needs of the teams and not of Pirelli. They are in danger to repeat the vicious cycle they have run through once already this year.

Also interesting point on tyres:

As we said early this year, perhaps we’d gone too far with the tyres and that meant drivers had to underdrive the car. In the race today the drivers were pushing, as they were in Montreal, and I think those kinds of races are exciting. It’s nip and tuck between the drivers and they’re fighting sector to sector. It was a close and tough battle today which shows that tyres don’t need to be so high in degradation to provide good racing. That’s what we saw today.

I do agree that the race was a good show and exciting. Such four way battles to the end always are.

lex Pirelli in today's published new technical regulation for 2014

12.6.3
Tyre specifications will be determined by the FIA no later than 1 September of the previous
season. Once determined in this way, the specification of the tyres will not be changed during
the Championship season without the agreement of all competing teams.
Notwithstanding the above, the FIA may decide to change the specification during the
Championship season for safety reasons without notice or delay

From now on the tyre supplier has no excuse. They can go to the FiA non public and have the specification changed. But it will be obvious to the public when they do and it will be very embarrassing.

You miss my point...on purpose?....Sam and Martin can say that because prior to Germany Pirelli had no REQUIRED pressures or camber settings,,,in fact Pirelli okayed swapping sides..Quite frankly because the tires are NOT uni-directional.
