They are bigger, but not exactly 20" or above. The rims just need to be big enough to accommodate the brakes and axle, any bigger is just a waste of weight/space. Maybe the mechanism in Nascar, etc are just more bulky and have bigger brakes since they don't use the same brakes F1 cars use? I don't think they use carbon fibre composite like F1.

In F1's case it's probably just standardized...doesn't contribute negatively to the car's performance as far as I understand. Since large rims just contribute to weight and smaller rims result in lesser rotational weight. They probably figured if it works, no need to mess with it.

I'm pretty sure Perelli (sp) are capable of making tyres that can last an entire GP, and as seen by qualifying, there's nothing wrong with the peak quality of grip they have.

At anyrate, causing controversy, won't help their contract, I think the contract hinges on well, if the FIA want low durability tyres, it seems like other tyre manufactures, don't think that is a good proposition for them.

I think Pirelli have already said they want to bring in harder tyres.

Sure, but if the FIA are going for harder tyres, they can get anyone to do that probably.

Pirelli were kind of in the wrong place at the wrong time. Had Bridgestone been the new tyre manufacturer, they'd have likely agreed to make what the FiA instructed them to make after Pirelli told them to poke it (as they'd be in a stronger position to do that).

Glad you're finally agreeing that Pirelli did something that they felt they wouldn't be able to effectively engineer. The ol' "I was just following orders" excuse.

I'm not finally agreeing to anything at all! I've always said that the tyres are not Pirelli's doing but the FiA's. It's been long established that Pirelli have not been happy with the fragile tyres for a while now but they're hand was forced by the FiA and a lucrative contract.

I think you're just actually taking the time to properly read. It's more fun in the sunlight.

You should be testifying in this FiA hearing with all this insider info you've got your hands on. It's also been long established since you write it in ever other post that they're simply doing what they're told to do. I've mentioned that a professional entity wouldn't prostitute themselves, their craft and their professionalism to make a buck, otherwise they're not so professional.

Hey, hookers are very professional!

[stonemonkey]

What exactly did the FIA ask Pirelli to make?

yeah but they've already claimed that spot. everyone else has to find their own gig.

ESPNF1 Pirelli expects to complete more tests similar to the one it took part in with Mercedes after the Spanish Grand Prix before the end of 2013.

The test caused controversy among rival teams as Mercedes took part in a 2013 car, which rivals Red Bull and Ferrari deem to be a breach of the Sporting Regulations. However, Pirelli motorsport boss Paul Hembery says his company has been in talks with a number of teams and needs to do more tests as it continues to develop its 2014 tyres.

"We envisage having other tests during the year looking at 2014, and we certainly will be hoping to have other tests with teams who are willing to perform in those," he said. "We were already in discussion with a number of teams and maybe some others will become available as we move forward because the change in 2014 is very dramatic. We saw some initial data from some teams and it was very clear to us that we would have to make very dramatic changes, hence the need to start testing new concepts and new developments."

Hembery said it would not make sense to invite all 11 teams as Pirelli is limited to 1000km per test by its agreement with the FIA.

...Pirelli’s Paul Hembery was at pains to point out that the Mercedes test was focussed on 2014 tyre development and that the only tyres intended for 2013 use were the ones aimed at fixing the delamination issue, with the 2012 belt pack made of kevlar replacing the steel belt....

Didn't Pirelli previously claim that NO 2013 tires were tested? This seems to say that Merc did indeed get to run this years car and this years drivers using the tires that (when they were doing the tests) were intended to be used in Canada - that's not good It would also explain why Ferrari, Red Bull and Lotus were so put out by this event.

I think what Pirelli meant to say was that Mercedes didn't or couldn't know they were this year's tires. English can be a bit confusing sometimes.
