Would be great if you want to start a family the way Pirelli tyres keep bursting can't see these doing much of a job. so have some rep on the house
http://www.bbc.co.uk/sport/0/formula1/23141389 Pirelli to use kevlar belted tyres this weekend and then 2012 tyres from Hungary onwards. Backs up the theory they'd secretly switched to a kevlar construction in my opinion, the fact they're able to get the kevlar tyres to Nurburg by Thursday suggests to me they were going to take them anyway. Could be in for another explosive weekend. Thankfully they've seen sense and reverted to the 2012 tyres from Hungary. Hopefully none of the teams will block it this time.
Sotonlad, the poles aren't the problem. Everyone knows Mercedes built a car with great single lap pace, but they were so hard on the tyres they slipped back significantly in the race. Whilst circumstances have played a part, that appears to be much less of a problem for them after their test
I've no idea who's tyre that is (it's not Vergne's because Toro Rosso have gold hubs or Perez's because McLaren have black hubs), but all the failures were on the left hand side and the R in the barcode indicates a right handed tyre. So either Mercedes, Ferrari or both were tyre swapping in Britain. This wouldn't have contributed to the failures if Pirelli were running kevlar belts by the way, because they aren't handed. Edit: Just noticed the inside of Mercedes' hubs are black too so that's Massa's tyre.
I understand where your coming from but teams are developing new parts all the time,And learning all the time from the car which they built. I no what they did was wrong but have they really gained an advantage maybe! I wasn't present at the track on the day the testing took place do I couldn't tell you if they were gaining an advantage or trying new parts who's to say the 2 Ferrari tests didn't try new parts on an old car because let's face it the cars haven't honestly changed much the last couple of years. Sorry if I upset or offend anybody but I feel mercedes are being hard done by. Anyway they have been removed from the young drivers test which will give everybody else a chance to catch up.
Great day for Red Bull, their three nearest rivals are all going to be weakened for the rest of the season, Ferrari and Lotus by the tyres, and Mercedes by putting Paddy Lowe in charge of development of this year's car.
Hmm… that's interesting, AG. I saw no evidence of steel in any of the weekend's failures. Nothing on what remained when cars made it to the pits, none of the flailing dishcloths biting at bodywork showed steel, nothing flying in the air (fortunately for Kimi in particular), none of the shreds in photographs (including Forza's), and no-one reported finding steel on the track. I have not the slightest doubt these tyres were kevlar belted. I'm not sure of the source suggesting that the kevlar tyres are not 'handed' but if this is the case, I find it surprising. As you say, all the failures were rear lefts, so if the kevlar belted tyres are not handed, the 'R' on the barcode would seem irrelevant. Perhaps Cpt.Silver swapped it to flummox us all!
Pirelli have said the tyres are the same as those used in Barcelona, so if they have used kevlar belted tyres (which seems certain) they're not admitting it, which means the R on the tyres is necessary for maintaining the pretence that the tyres are the same as the ones they had before. The source suggesting they're not handed is from the same article in BLS' quote: Kevlar belted tyres are not ‘handed’ meaning they are identical on both sides – in other words there is no point in swapping them around. And that means the teams that have been routinely swapping will lose the advantage they currently have, and that in turn explains why they a) they are now fighting with Pirelli and the FIA over the planned change and b) why those teams who have not been able to make tyre swapping work, or have general tyre issues, are only too happy for it to go through… http://adamcooperf1.com/2013/05/28/...eal-change-will-handicap-tyre-swapping-teams/
I found an article on the logistics of shipping tyres around Europe: Pirelli say they're "changing" to a kevlar belted construction for the German grand prix, but it would've been logistically impossible for them to manufacture and dispatch the tyres in time for Friday morning practice. The drive from Izmit to Nurburg alone takes 25 hours, it would be longer in a lorry, and EU law states that an HGV can only drive for nine hours a day, meaning the drive would take almost three days with no delays. Also four hours of delays (equivalent to less than ten minutes per hour) would result in a 24 hour delay because the HGV driver would have to park up for 15 hours to rest, meaning if they'd been dispatched this morning they'd get there Friday night. And that's just the drive that's virtually impossible, they'd also have to manufacture three thousand tyres (they wouldn't just happen to have three thousand kevlar belted tyres of the right compounds being stored at the correct temperature) and mount them all on rims for the teams. They're not changing the tyres for Germany, they were taking them all along.
Well, I scarcely know what to say, AG! If your suggestion were found to be correct, such deliberate deception would be a seriously bad move by Pirelli; and might invite legal action over and above more obvious breaches of contract. For this reason, I personally find it a bit too much to swallow at the moment. Any manufacturer of racing tyres knows the very great likelihood of their product coming under scrutiny in the event of failure. Even the most ordinary puncture can reveal simple facts about a tyre's structure. In my opinion, such a deliberate deception would be far too big a risk for any common sense company to consider â especially a global one currently under the spotlight of the highest profile of all! If what you're hinting were found to be true, its revelation could be disastrous. Although I am at a loss to suggest anything else, there simply must be some other explanation.

Well, whilst I've come to be somewhat dismissive of our representative at the BBC, Pirelli's comments in Benson's article about swapping the tyres would suggest that the kevlar belted versions are not identical on both sides – which is what I would have expected. As I said earlier, I found the suggestion that they were not 'handed' very surprising. Then again, I concede Adam Cooper* may know something I'm unaware of; and that this is probably more likely from him than Benson! *I should also concede that until following AG's link, I was unaware of Cooper himself but most people seem to know more about F1 than Benson…
They don't just blame the team but "what it described as "high kerbs" at Silverstone". So basically anyone but themselves. Idiots. Anyway here's a little bit more information about the Silverstone tyres - it wasn't a direct switch to kevlar tyres, but a brand new construction: Pirelli are a joke.
Can i ask a maybe stupid question, but why did Pirelli feel the need to change the construction of the tyre, to include a layer of kevlar included in the internal steel-belt ?
Hi Sporty! My understanding is that Pirelli took measures because of previous delaminations with steel-belted tyres, which (they claim) were not safety related but based on the public perception of their product. I am truly shocked at some of the things I'm now hearing. Some of these rumours seem to be suggesting that my earlier defence of Pirelli's integrity as a company (a few posts above, here in this thread) might have been naïve. Two things I should add from a personal perspective: 1] I find the suggestion that Pirelli might produce 'ambidextrous' tyres which can be used equally on both sides of the car (completely symmetrical in every aspect of their design) a great surprise. 2]a] If point 1 is correct, more disturbing is the suggestion – alluded to (above) by AG – that there may have been a deliberate attempt to disguise it with stickers denoting (irrelevant) right or left handedness. b] However, I think it likely that such stickers may have been applied after placement on the wheel, in order to ensure subsequent use from the same corner of the car, since tyre wear can induce its own 'handedness' regardless of inherent design.
