Glad Pirelli don't make our race tyres

[johnboy]

So glad Pirelli don't make rc tyres after today's British gp ha

[Nas]

I am totally shocked and annoyed!!

FIA need to view their contract with Pirelli, its a simple piss take, even after their 1000km tyre test with Mercedes.

Burning rubber hit Kimi directly at his helmet and was in his cockpit at about 180mph.....

Massa crashed out at 145mph,He could have been going MUCH faster....

Sebastian's right rear was split when he made his pit stop! thankfully he came in just in time, still feeling really upset from Sebastian loosing 5th gear and ruining his gearbox ruined his race at first i thought it was a sensor issue with the gearbox as it seemed like he had all the gears, but that 5th gear ruined the gearbox. Really very annoyed, but looking forward to my home Grand Prix next week Sebastian will pick up some good points there.

Back to the tyre issue, is it tyre deg? are they overheating?
Sebastian normally runs 16 to 18 PSI but due the tyre problems their Pirelli tyre suggested to add 2 more PSI, the high pressure had a effect on traction and it effected his lap times....

It has to be Tyre deg or serious overheating. Normally tyre deg is easily monitored but something was SERIOUS wrong and Pirelli need a serious sit down!

Or.... Turn 4 and 5 Kerbs seemed to "RAZOR SHARP" Apparently, maybe that's the issue? but we saw other drivers hitting turns 4 and 5 without any issue... unless Bernie Ecclestone has installed Gremlins in the teams he doesn't favour haha!

Paul Hembery-PIRELLI motorsport boss isn't happy at all and has taken samples back to the lab for serious reviewing before the German Grand Prix,Bernie has given him a bit of a "telling off" that'll make no difference....

Let's see what happens....

I hope Pirelli don't make condoms;-)

I am very happy vettel broke down.

Tyre issue, well its there own fault!

The only problem would be if their customer told them to make them fall apart after limited use, like in F1.


Nothing stopping Pirelli making rock hard tyres that last forever, like the Bridgstones, but that's not what they've been asked to make. If they did Red Bull would be lapping the field at many races.

Silverstone created stresses that Pirelli hadn't found in testing, which we all know is something they can't do without it causing chaos amongst other teams. Tyres were overheating Teams running low tyre pressures putting more stress on the shoulder. Sharp kerb edges catching the tyres if they ran right over them. Then lets throw in the teams that wouldn't allow Pirelli to change the tyre construction to last years design, but did allow Pirelli to change the gluing method so they don't just delaminate the tread any more.

It's not just the tyres, if it was entirely down to the tyres we would have seen them exploding in Canada, but it doesn't help that they can't test them on modern chassis. It's like only testing tyres on a Ford Fiesta and guessing they won't explode on a Ferrari.



And we used to have tyres just like that in R/C, go back 10-15 years and touring cars and buggies had plenty of one run tyres, that's why we now have tyre limits and spec tyres these days.

I actually have a lot of sympathy for Pirelli, they were asked to make tyres that would degrade to help the racing/show - and to do so with a very limited amount of testing. It's hardly surprising that there are issues - and let's not forget the teams always leave no margins (you run the tyres as low as possible) and only had add 3/4 psi to the tyre pressure to stop it happening. (Which is what they did eventually)

It was a shame but it is actually good now that it did happen. Now everyone is running around changing rules without approval to insure that it doesnt happen again. It also proves home of the british grand prix is still one of the most demanding tracks on the f1 calender.

There's a 'simple' solution to this - and to Mercedes testing tires and everything.

Just give all the teams ... hours of testing with one or more tire solutions Pirelli comes up with, and give them the same set of equipment to monitor the tires so it's down to the skill (not the wallet) of the teams to find what they can do with them. At the same time Pirelli is getting the data from all the cars from this year and can look into the potential causes of the problem.

I think Pirelli will agree on it that the drop off is a bit too sudden right now I don't think they have the belief tire blow outs in F1 are good for their reputation and will boost sales, so they'll be determined to solve it as much as the fans want to see exciting fights not abruptly ending because of technical failure.

[Burty248]

There is no point in this if you give everyone the same car to test with as it would have no reflection to the current cars. This years cars are maxed out versions of the v8 cars they are the fastest and best they will ever be for years to come. That is why tyres are failing the tyres just cant take the current forces the cars are giving them. Pirelli are using a 2010 renault car to test the tyres which due to being 3 years old is probably slower than that of the caterham and the marussia.

[Origineelreclamebord]

What I mean is testing with their own current cars... however, restricted to certain monitoring parameters for the racing teams to make sure the bigger teams don't throw in more money to monitor more parameters or more accurately. On top of that Pirelli can decide what they'll be monitoring on the tires and they will keep that data for themselves. That means 11 different cars to test with for Pirelli and no distinct advantage between any of the teams, though it does give all of them a good opportunity to look into the tires.

[Just wondering if tyres explode like that in the German GP will the team/drivers will refuse to race as they did in the Usa GP 2005.
Ok in 2005 they had to run the whole race on one set of tyres but the Michelins were blowing up Ralf Schumacher was a bad case. They could have sorted it with the addition of a chicane but the Fia would not allow it.
Hamilton came straight out with blaming Pirelli on Sunday and saying it was dangerous, so maybe the teams wont want to risk their drivers if the blow outs happen next weekend.

It is Pirelli's problem. They changed the carcass from kevlar to steel for 2013 in order to get it closer to a proper radial (Pirelli were one of the first with road car radials) away from a bias-ply carcass. This was when the tread delamination started. They tested a new way of fixing the tread to the carcass which worked, that's when the disintegration problems started.

The issue here is not wear, it is the failure of the tyre when it is cut by debris, or allegedly a kerb. It will fail at the weakest point. That was the tread's adhesion to the carcass, and since they fixed that the weakest point moved to the carcass itself.

For Germany they are proposing to go back to the bias-ply kevlar design as that will resist cuts better especially to the sidewall. From Hungary onwards they are proposing to go back to the 2012 tyres with the kevlar bias-ply construction and last year's compounds. The other advantage of the kevlar construction is that, if there is a catastrophic failure, the bits flying through the are are lighter and not made of steel so will cause less damage.

Amid all the hype and unfounded conjecture the root cause of the problems seem to have been lost. The problem remains that a catastrophic tyre failure at circuits with barriers closer to the action, like Hungary, is very dangerous. Now that the FIA and FOCA have played the safety card, we can expect action. IMHO the worst part of this is Pirelli being too worried about their image to call "safety"in the first place so they could make these changes before the British GP. It's come to a pretty pass when they seem to have risked a serious accident because they don't want people to think their road car products are unsafe.

Pirelli have now issued a statement blaming the teams for the tyre failures. "they put the rear tyres on the wrong way round"

[SlowOne]

It's difficult to believe that they can, after all that has gone on, leave it two days to say anything at all! And then to say it is all the team's fault...

They tested with Merc using a 2013 car - did they really only try tyres in the way they were supposed to be used, and not in the way teams were actually using them? Shades of new Coke and Toyota recalls here in the PR department!

Roll on Germany with better tyres and some racing that does not risk life and limb.

[bodgit]

They have now retracted their statement.
