F1 » F1 Bahrain 2013: Whitmarsh, Horner expect Pirelli to react


Teams/people that are complaining about the tyres have a vested interest to do so, some cars on the grid tyres usage is more extreme than others, Mercedes had tyres problems for the last three years, RBR seems not to be quite there this year (certainly wasn’t in China) “the car feels good but it’s just not quick (Webber)”, mclaren are starting from Zero regarding tyres behaviour with their new suspension design. Some drivers instead of just looking after the tyres can drive them to the maximum they can take but without over driving the car, but others when the car is not quite there they tend to overdrive the car and so the tyres, The FIA wants two or three pit stops during a race and Pirelli is only doing what it has been asked to do, The tyres even if at varying were always the limiting factor in a race and that for as long as I can remember, Pirelli/FIA will not revert to 2012 tyre compounds.

F1 » Chinese Grand Prix 2013: Massa mystified by mid-race dip


Actually at the first face of the race there was a time when Massa was pushing Alonso (was a shade faster), I do not believe this graining problem is driver related (Rosberg) had it too), it is more to do with the tyres being in the temperature operating window which can be greatly affected by suspension setting. There might be something the teams are using to sort of stabilise the ride height that is still a highly guarded secret which is not yet perfected and is effecting tyres behaviour when not working as it should.

F1 » F1 China 2013: Penalties for Webber and Gutierrez


Richard, re Webber wheel problem, Webber’s wheel did come off while driving slowly but he did notice and reported the problem as soon as he came out. I am certain that most teams are now using the wheel nut system as pioneered by Ferrari, that is the wheel nut is part of the wheel now (it stays inside the wheel rim when the wheel is removed) and not come out with the wheel gun, the nut is cercliped loosely into the wheel rim in a way that makes it virtually impossible to cross thread when using the gun to thread it in, I am also certain that using a single retaining nut the threads are left or right handed according (counter) to the rotation of the wheel, any clips/fingers/ nut retention system will prevent the nut from rotating only if the nut is fully home and fully torqued, otherwise these clips/fingers will not prevent the wheel coming off.

F1 » F1 China 2013: Penalties for Webber and Gutierrez


Prof x, the conspiracy theorists you included doesn’t realise that they are ridiculing themselves apart from contaminating this site. Richard, as I understand it after Ferrari came out with a wheel that contains the wheel nut (wheel nut in wheel) everybody followed suit, this system is impossible to cross thread, they might not have locks any more, in that case the wheel nut threads would have to be left or right handed (the same like the old style knock on wire wheel nuts if you know what I mean) , Horner said that the nut was fully torqued, so what was at fault?
