Pirelli bring tyre changes forward to Canada

2013 Spanish Grand PrixPosted on | Author Keith Collantine

Sergio Perez, McLaren, Circuit de Catalunya, Barcelona, 2013Pirelli will introduced revised tyres in time for the Canadian Grand Prix, the official F1 tyre supplier has announced.

The changes are being made to guard against a repeat of Sunday’s race in Spain, where most drivers had to make four pit stops, and to put a stop to the delaminations suffered by some drivers in recent races.

“From Canada changes to be made to bring back two to three stops,” Pirelli’s motorsport director Paul Hembery said on Twitter. “Some structural changes combining elements 2012 and 2013 products.”

Hembery explained the thinking behind the decision: ??Our aim is to provide the teams with a new range which mixes the stability of the 2012 tyres and the performance of the current ones. As a company, we have always moved quickly to make improvements where we see them to be necessary.

“After evaluating data from the first few races this year, we?ve decided to introduce a further evolution as it became clear at the Spanish Grand Prix that the number of pit stops was too high. The Spanish Grand Prix was won with four pit stops, which has only happened once before in our history.

“These changes will also mean that the tyres are not worked quite as hard, reducing the number of pit stops.

“With limited testing time, it?s clear now that our original 2013 tyre range was probably too performance-orientated for the current regulations. However, having identified this issue, we?re determined to rapidly resolve it.

“It?s worth underlining that the current regulations for winter tests limit the opportunity to test the tyres under the same conditions as the race season because of the lower temperature and restricted time. The teams are of the same opinion as we are in wanting longer testing times and different locations for the next tests. We developed the 2013 tyres on the basis of careful simulations that were, however, not sufficient, taking into account the improved speed of cars (up to three seconds per lap).

“We?ve also taken this step to avoid the delaminations that were caused by track debris. It?s important to point out that these delaminations, which occur when the tread comes off, do not compromise the safety of the tyres as the core structure of the tyre is not affected in any way, helping drivers to complete the lap and to change the damaged tyres safely. These delaminations were due to damage from debris that overheated the tread.

“We?d like to thank all the teams for their continued and extremely valued support as we worked with them to identify the correct compromise between the pure speed that makes us the world leader in the ultra high performance sector and a global spectacle that is easy for Formula One fans to follow.??

Pirelli previously announced it would not make changes until the following race at Silverstone. It had warned that making changes to its tyres could be seen as favouring Red Bull, who have lobbied for changes.

Pirelli has allocated the super soft and medium tyres for the Canadian Grand Prix.

  1. What are the protocols on such decisions? Does every team have to agree like with testing? Ferrari would never lie down if it erroded an advantage so that the change is happening and not a word from ferrari means this must be good for them? Pirelli must have given details of what they want to achieve and ferrari must feel its good for them. i hope the new tyres bri.g bigger issues for rb and ferrari + lotus hammer them by an even greater margin in canada, then what? Have rb made an agreement about testing to get ferrari on board? The stories behind the headlines might be very complex.

  2. ferrari does employ Bridgestones former technical chief, no other team boasts such an advantage. And to say this change only helps a few is myopic and silly. Everyone from Ferrari to Lotus has said that they are only driving at around 80%. Well, Force India might actually have to prove they have a good car and not one that is easy on tires.

  3. I think this is getting silly.

    First: if Lotus, Ferrari and Force India can do so much good with these tyres, wouldn´t be safe to asume that they will still be good with the new modification? They could be races where Lotus only has to do one or two stops. So I don´t see a reason to feel sorry for them. And two days a go everyone (Mercedes, Lotus, Alonso, Button, Perez, McLaren) was crying about what an horrible race Barcelona was so people better start remember that.

    Second: I dont watch F1 to see drivers let in themself get pass. So I wanna see racing and if this new tyres gonna allow racing bring it on.

    Third: Safety was a concern with this tyres, so maybe people should think in the well being of the drivers.

    When Pirelli says the tyres from Canada will be more like 2012 tyres what does that mean?

    The 2012 tyres were more durable than this year’s tyres, which suffer from high degradation. Pirelli has indicated that it will change the construction of the tyres to be more like the 2012 products.

    The 2013 tyres have a different construction from the 2012 products, with a steel belt inside the tyre in place of last year’s kevlar belt. It is likely that this decision will be reversed with the revised tyres, as Pirelli moves back to a proven solution.

    The weakness of the 2012 tyres was wear; typically the inside shoulder of the tyres would wear out and teams would run the tyre until there was no rubber left on the shoulder and then make a pit stop. However the teams understood how to manage them quite well by the end of the season.

    For 2013 Pirelli tried to fix the wear problem by getting the contact patch of the tyre more reasonably positioned, but it seems that in changing the construction to achieve this they have gone too far.

    Although the reason given for the change is that four stops is considered too many for a race and they would like to reduce that to two or three stops, there is also the safety aspect in light of the tyre failures in Bahrain and Spain. In changing the construction, they have obviously done something to affect the tyre’s integrity.

    So don´t come saying that this is only because of Red Bull

  4. Fantastic news!
    In all fairness, the delaminations, slow punctures and tyres generally ripping themselves to shreds was becoming a worry if anything.
    I understand completely where people are coming from in the defence of Ferrari and Lotus’ ability to compromise their cars correctly for the current tyres to perform well on their cars.
    However if you look at it from RBR/Mercedes point of view, they are only being shot in the foot for producing cars that don’t perform as well on the tyres, now the balance has shifted, Ferrari/Lotus are being shot in the foot for not producing cars with enough downforce to compete with the quicker cars, it seems whatever Pirelli chose to do, the disadvantaged teams would have to adapt to compete, only by going down this route we have a few positives:
    1) Safer tyres that aren’t going to shred themselves.
    2) Tyres that allow drivers to push harder, thus focus more on racing, opposed to tyre strategy
    3) Less Pit stops

    I am no Red Bull fan, infact, I have found seeing Sebastian Vettel cruising to three titles painful if anything, but I’d see him win a fourth any day over the utter nonsense I saw in Barcelona.

    But being a Hamilton fan, maybe I’m biased ;)

    1. +1

      I really can’t stand Vettel, but I’d much rather he cruised to a 4th title than watch another ‘race’ like Spain. I don’t want the worlds best drivers say “I can’t drive any slower” or asking “Are you sure I can race?”

      I say give them overly hard tires like they did in Austin 2012… lets the cars race 100% in a low mechanical grip environment.

  5. Since new parts are in development for months, this big change means that many teams will have their 2 or 3 months worth of work thrown to trash basically. Since the pre-season testing it was obvious that tires are yet to be mastered, so many developments will be targeted at addressing the tire issues.
    Now, with this change, it means all the development that went into improving tire usage will go down the drain. And not only that. The different aerodynamic characteristics of the new tires means that many teams will find their successful aero updates suddenly not working.
    This is complete farce.

  6. I see a pattern in this thread. People who tolerate comedy tyres are the people who are happy Red Bull isn’t winning. They are selfish because they want to see their own teams win. I paid money to watch cars being pushed, not tyres deciding how much a car can be pushed, or tyres degrading. For those who love this tyres, there’s a better sport for you. Go to youtube and search ‘tire burning’. It would roughly amount to what you are watching now. -cough- James -cough-

  7. I’ve been at two F1 races this year, Melbourne and Spain. The tyres are a joke. We nolonger see the guys racing as much as they are baby sitting thieir tyres. I’m also concerned about the vast amount of clag that scrubs off them narrowing the actual track. I agree with David Coultard that its a serious accident that’s waiting to happen. I’m young bu have watched formual 1 since 2000 and think the 2 tyre compunds are a gimmick. I would much rather see fuel stops with the teams given the option of how much furel thay want to start with after Q3. That way its not about tyres but allows strategy for number of pit stops and car weights and speeds accordingly. F1 is losing TV ratings around the world. Who wants to talk about tyres…when it should be about driver skill and car design.

  8. If possible the week before Canada the F1A should find a place and let all teams test all the compounds and the F1A should foot the bill. This would give at least some expectations as to where the new tires are for everyone.

    I know, not happening but a reset is not fair to any of the teams imo.

  9. I’ll wait and see how the tyres actually perform but I’ll look back on this in hindsight and say this is BS if Vettel runs away with the championship the rest of the season.

  10. Results Barcelona 2011 when RedBull with Vettel just had a walk through the seasson to win with over 120 points to 2nd:

    1. Vettel – 4 pit stops
    2. Ham – 4
    3. Button – 3
    4. Webber – 4
    5. Alo – 4

    2011 – Total pit stops: 77 with 21 cars finishing
    2013 – Total pit stops: 81 with 19 cars finishing

    Don’t remember Horner or Mateschitz whinning back then…
