Fair enough, still not F1 tires.....

Finally - how anyone can suggest the GP2 tyre is the same as a F1 tyre needs their head testing. They are both round, and rubber but thats where the simularities end. They have a complete different make-up, differnt compounds etc!
This argument is in istelf absurd. The F2007 was designed to run with grooved tires. Different compounds, construction and a significantly smaller contact patch. And, by the way... WHO CARES!ISLAMATRON wrote:jason.parker.86 wrote:with Gp2 tyres (which one can buy from eBay).

The absurdity of that statement in bold is self evident...
and like others have pointed out, the F2007 on the GP2 tires was faster than the F60 test from this winter, if that does not speak of the similarity of the GP2 tire then I dont know what does.
Those of us who have been watching this sport for a while remember that when GP2 debuted they ran the grooved tires but the next year switched to a slick tire and the reason given was that GP2 was to be a test bed for technology and rules for F1 as well as a feeder series. Bridgestone often spoke about the similarities between its GP2 slicks and what it was developing for F1, and this is not the first time a GP2 tire has been fitted onto an F1 machine.
The GP2 tires are the exact same dimension as the F1 tires and I would guess they are made on the same exact machines, yes the construction(mainly side wall stiffness) and compound may vary slightly but not by too much seeing that the 2 series run on the same venues.
The 2 compounds cannot be too different, or else there would be compatability problems when they run the same track on the same weekends. And the durability must be there seeing how the GP2 feature races are more than half(60%) the length of the F1 race.
There are 3 different compounds, soft medium & hard of GP2 compound.RacingManiac wrote:But GP2 tire can be "similar" to F1 tire, but its not still not F1 tire. Its unlikely that the GP2 tires have more than one compound and construction, while F1 tire, albeit dialed back from the tirewar days, still features 4 variant design to run on specific type of tracks. It is likely that GP2 tire is more conservative in its makeup(read, durable and longer life, less grip).
Besides, this still does not violate any rules at all. They are running 2 year old cars, without the race team crew, they aren't using current F1 tires(Cats and lions are similar, but a cat is still not a lion...). So what have they done wrong so far in this?
The spirit of the rules is that no driver gain additional in-car practice and no car additional development beyond their competitors.ISLAMATRON wrote:Never said it violates the rules, but it does violate the "spirit of the rules" which was Ferrari's argument against the DDD's. If he got a day of testing in the F60, it would violate the rules, unless of course the teams agreed to it. He should only be allowed straight line testing, just as any other driver would this year, regardless of who he is.
