Pirelli's motorsport director Paul Hembery has repeated at Korea that F1's sole tyre suppliers need to have more relevant tyre testing if it is to develop solid and reliable tyres for the 2014 season.
I dont know what race you saw... In china we had tyre conservation cause the softs were not even on the limit but beyond it.bhallg2k wrote:The opening laps were fantastic. As usual, however, the race soon settled into the war of attrition we call "tire conservation," and that just doesn't do it for me.
More s**t from PirelliWind tunnel tyres to blame for team struggles - report
Pirelli's new 60 per cent scale wind tunnel tyres could be to blame for some teams' troubles in 2013, according to a technical expert.
Top team McLaren faltered badly over the winter in switching from the winning 2012 car to the new and uncompetitive MP4-28.
And it's been a similar story at Williams and Sauber, who last year were among the standouts of the midfield and are now conspicuously scrambling for pace in 2013.
Referring to McLaren and Sauber, Swiss newspaper Blick's technical expert Mike Hammer writes: "Both teams now believe they know where the problem lies.
"It has to do with the new Pirelli tyres. They are more angular than in 2012, and then deform differently in the corners, which has a great influence on the aerodynamics.
"Millimetres play a role, but the 60 per cent tyre for the wind tunnel models have led McLaren and Sauber astray," he added.
An unnamed McLaren engineer agreed: "They (the Pirelli tyre models) are much worse than last year."
Faced with the latest criticism, Pirelli's Paul Hembery insisted: "We are talking about eleven teams with eleven different wind tunnels.
"It is not easy to build good 60 per cent tyres," he added.
The theory would explain why teams who made significant changes over the winter have disproportionately suffered so far this season.

I'm quite unhappy about that as well. Tyres should never fail in a control tyre period. We have seen far too many problems lately that were safety relevant. I wish the FiA would start an investigation and that the reported contract extension rumour were incorrect.Dragonfly wrote:I am far from knowing the basics of a racing car suspension setup, but two tyre failures in a short period and at the same wheel seem to me quite peculiar. Didn't see how exactly the first one delaminated but the second one was shown in a replay from the backward looking camera. On a straight, looks normal and then in a blink disappears from the rim. As if the inner sidewall exploded along its entire circumference.
Yeah, they would say that, sure..Pirelli believes debris was to blame for both of Felipe Massa's punctures....
[Hembrey said] "People are doubting that it was debris, and saying 'yeah you would say that, sure' ..."
I was thinking along the same lines. What's your opinion on the left front having less DF(broken FW) and the right rear having more load contributing to the tyre issue. I mention again because Rubens mentioned this as quite possibly being a contributing factor.Jersey Tom wrote:Well, how can ya call it a puncture when the tire isn't punctured and is still holding air!
Interesting that there's been debris all over the tracks for the last couple of years and we've seen nothing like this. This feels like something new. What is even more fascinating is the punishment the tyres can take and stay up - look how Perez carved a line into Button's tyre when they touched and that didn't deflate or explode - neither did Perez' tire when Kimi smacked it hard in Malaysia, neither did Webber's after smacking Vergne quite hard.abw wrote:http://www.autosport.com/news/report.php/id/106975
