Pirelli will take Bridgestone's place after 2010

[Jersey Tom]

Nah. They're not. Sorry.

[ringo]

I think all that matters is that everyone is using the same tyres and that the tyres are safe. I couldn't care less about how much grip it has than the other brand if the other brand were to make them. Everyone's using it and it's made of rubber.

What interests me more than anything is how it grains. I know little to nothing about tyres, so it would be interesting to see how the pirelli behaves as it wears on different surfaces and in the different conditions.

[Just_a_fan]

Michelin are lot quieter and less rollind resistance for equal grip as any of the tyres mentioned

A recent tyre test by a UK car magazine suggests otherwise. But hey, why worry about back to back studies when you can have prejudice instead...

[godlameroso]

i don´t see this transfer from track to road or even semislicks.
If you happen to find a tyre that really suits your car even a Hanlook or Kumho might be the ultimate..for your needs ..
I´m always amazed that even seemingly professional teams don´t really know what they stick on their rims and take things a bit grantedas Michelins are best and Pirelli are inconsistent-inconsistent in what?- do we know if this is in the tyre or how it was stored and how long? Constant asking of your tyre supplier will build knowledge and maybe tell you who to ask and when...all of a sudden things will fall in palce and the semingly bad product starts to show strengths you never thought possible.
But then who am I to know.

Exactly my point, Pirelli's F1 tires, especially the ones that are being planned for next season have very little resemblance to anything they have made before. I don't have any doubts that Pirelli is capable of designing a tire that will work. I'm sure that Pirelli's engineers know what kind of forces they have to deal with, will the tyres be better than Michelin or Bridgestone is practically irrelevant as there is no competition. What I would like to know is how sticky they plan to make them, will the tires offer more grip? What kind of operating window will they provide?

Pirelli proposes that it will think of implementing michelins idea of 18" wheels in a couple of years.
There was a discussion on the dead weight of the wheels being some 30kgs more. F1 uses magnetism alloy wheels. Why is there no wheels of carbon fiber, is it impossible to make a F1 spec wheels with carbon fiber?

Reason why there will be a 30KG weight increase, sinply put the magneasium alloys are best suited to the job over Carbon wheels, simply put, they are better suited to loadings, and last a longer period of time. Carbon wheels would only be allowed to be raced for about 4-5 races, where Magnesium alloys will generally last up to half a season on average.

On the basis of cost, not to mention man hours to construct carbon wheels. Magnesium wheels only need a block of prime metal and a CNC machine to get to work, between 4-10 hours later you have a wheel, a carbon wheel takes much longer to construct.

Im expecting the weight of the car to go up from 640KG for 2011-2012 to go arround 675KG to compensate for at least some of the weight. The thing is, that the wheels will weigh arround 30KG more, the suspension will be up to 20KG more, but the engines will potentially weigh less and with the posibility of a standardised fuel tank on the horizon for the new engine as well, will also reduce weight in another area.

basically a tyre designer has to decide what he wants from his product ..if you want the ultimate in life you won't get the ultimate in adhesion ; if you think of it logically motor racing is at one end of the spectrum , life is sacrificed for grip

in a one tyre series the manufacturer has to decide where he wants to place his product , and , as we have seen , bridgestone have been conservative and produced tyres that have enabled a one stop strategy , everyone with the same strategy

as we saw in canada , much better racing when the tyres are more marginal ; will pirelli give us tyres like that ? well , I think there is a real chance that they will
although only number 5 in total sales worldwide pirelli are number one in the high performance vehicle segment ; whereas other manufacturers like bridgestone and michelin carefully guard reputations for long life , pirelli carefully guard their reputation for the ultimate in performance , and design their products accordingly

on this basis they may be more willing to risk adverse comments from drivers about their tyres going off ....let's hope so anyhow
I expected to see a duel between button and hamilton this year with button squeezing extra life out of his tyres for one stoppers ,hamilton going for it and having to make two ; unfortunately bridgestone have brought tyres that enabled hamilton to squeeze a one stop strategy ; the corollary is that we have had cars starting the races lacking sufficient fuel to finish the race except by saving fuel ...not something that I personally want to see

pirelli may have been the prime mover in the change to 18" tyres , 18/20 inch being where they make their profits , but at the end of the day 2011/12 was too short a lead time for the teams and they had to accept that , as would any other company who took the contract ; in the meantime the 13" is old technology so they will have little development to do ...more some testing to decide on the tyre range...lets hope for some exciting racing with alternative strategies !

The new Pirelli rubber will start to get tested in late August by a couple of the GP2 teams that are getting their new for 2011 GP2/11 car that will be more like a current F1 car with narrow front tyres, wider front wing with FFA and narrower rear wing and no wings hanging off the bodywork to reduce drag. This is all because for the first time, the GP2 guys will run on F1 rubber for their races, altho it will be the hardest F1 rubber avalable.

With this, it has also brought the posible modification of the GP3/10 chassis suspension to also run F1 rubber as well, but the GP3 guys should run on a bespoke tyre for a few more years yet.

I think it would be a good moove for the potential 2013 Tyre War for Michelen to run their 18" tyres in World Series by Renault, Superleague Formula and Auto GP if they can afford that. At least get their rubber tested and proven in other formula before a posible tyre war in 2013 on 18" rubber.

Ideally Pirelli will start testing in a current or previous F1 car with comparible performance to what there currently is, the Toyota TF110 thing is the ovious way, but isnt clear cut with Toyota being linked to providing either ART or Hispania with a chassis for 2011. However they have been looking into the fact that they could use a car and power that isnt on the grid anymore, enter the posiblilty of a Honda RA106 or RA107 with a Honda RA808E engine as nothing directly to the current Mercedes cars, the only thing is that it will have to be wired for the SECU and have a couple of steering wheels made up for this as well. As for development drivers for the development car, there is 3 main candadates; Kazuki Nakajimma, more probable if they decide to use the Toyoat route; second Anthoiny Davidson, more probable if they were to use the Honda route; and the third and most glaringly obvious is Kimi Raikkonenn as he is likley to stay in WRC next year, and would be a good driver to drive the pants off the tyres for pure pace.

Personally, i think that Pirelli should test in at least 2 diffrent cars, the Toyota TF110 and the Honda RA108 or RA108 would be my choices, that way they can check base data and have at least three-4 day tests before the end of the season as to get enough data they can. Then with the most probable end of season test in Abu Dhabi with the 2010 drivers in the 2010 cars, have a four day test there with each team having 5 sets of tyres avalable to them each day to get data. The only thing is that it hasnt been made clear who supplies the tyres for the young driver development test at the end of the season, Bridgestone or Pirelli.

Why would the wheels be 30kg, or 66lb more?
I hope that isn't per wheel.
I don't think that number is accurate. If it's for 4 wheels, that's about 16.5 lb of metal per wheel. How much do the current 13" wheel weigh?

[marcush.]

the bmw chassis of 2009 would be an option as well..
how far were lola with their chassis?

but ,in all honesty the best option would be to test solely wit Lotus,Virgin and HRT...that would be a real help to them to reduce the gap and who does fear the newbies?

That number seems a rather uneducated guess. A BBS forged magnesium 18x10 inch wheel weighs about 6.5kg which is about 16.5lb, and that's for a road car. I'm sure they can make F1 wheels weigh less
http://www.wheelweights.net/wheel-weight-weight.pdf

I'm sure they can make a lighter wheel for an F1 car, even if we use this as a rough guideline that 26kg or 57.2lbs for all 4 wheels add another 6 kg for tires, that's 50kg total, or 120lbs. Therefore you'd be saying that current F1 wheel/tire combo are 20kg total or 5kg each per wheel/tire combo.

A lightweight 13x10 wheel weighs about 5kg by itself assuming a 6kg tire that's 44 kg for 4 wheels, a difference of 6kg for the total weight of all four wheel/tire combos, I doubt wheel weights will make much of a difference to overall performance, more than likely the size of the wheels will make the car slightly harder to drive, as there is less sidewall deflection and hence the car will be less forgiving.

edit:dyslexic math

[ringo]

Yes, the fact that an 18 inch wheel is about 16lbs. It would be amazing that an F1 car wheel would be 16.5 more pounds added to the 13 inch wheel. So that 30kg more seems inaccurate. I think i saw it in an article online as well. Could be a scare tactic to ward off using 18" wheels.

[WilliamsF1]

My mustaka then about the 30kgs. If I remember it was mike gaskony who mentioned it in his interview.

[CMSMJ1]

you would not want another 30kg flying off a car in an accident so I doubt anyone would try to make them heavier..... the tethers have a hard enough time as it is..

[audifan]

would be some reduction in tyre weight to help offset any increase in wheel weight , bound to be a big decrease in aspect ratio
