Pirelli have unveiled their new tyres for the 2012 Formula One championship. All four dry weather tyres will be more squarer and be made of softer compounds to compensate for the new aerodynamic set-ups of the cars. Apart from the technicalities, the colour markings have also been adapted for visibility purposes.
That's a bold statement.NonNewtonic wrote:Yes indeed a more square profile tyre will push the engineers to run more camber to gain maximum grip which increase the risk of blisteringneilbah wrote:if the profile is more square, would this make the use of camber outside the design limit more detrimental?

Yes. Ferrari also forced Bridgestone to produce rounded shouldered tyres throughout that era, even though they then had less mechanical grip, for aerodynamic reasons.PNSD wrote:Did not Renault cite one of the reasons they lost performance from 2007 onwards was because of incorrect wind tunnel calibration, and CFD modelling relating to the change in profile from Michelin to Bridgestone?

Perhaps they did. But there are indicators that the mechanical constructions of the Michelins and Bridgstones differed substantionally. The difference required the c.g. to be moved forward for mechanical, rather than aero reasons. Aero changes followed, rather than lead, the c.g. change. The history of the 2007 onwards Bridgstones has already been aired in these forums.PNSD wrote:Did not Renault cite one of the reasons they lost performance from 2007 onwards was because of incorrect wind tunnel calibration, and CFD modelling relating to the change in profile from Michelin to Bridgestone?
