Certainly Goodyear in the '80s and early '90s were terrible too, but I do agree Pirelli is the worst.
I think that'll sort it. Of course, one could say that the drivers know where the tarmac edge is and they should stick to it. If they drive on to the dirt and get a puncture, that's their problem. To blame circuit or tyre is a bit silly. Perhaps that's why we haven't heard any blame from the teams this time. They know their drivers caused the issue.
I think the problem wasn’t with the compounds but the structure of the tyre. I believe the structure stays the same across the whole range of compounds. When they give a stint life, in laps, for a compound they are a estimating a performance limit due either to wear or thermal degradation. They use tyre pressures to try to ensure the structural, fatigue, limit is beyond the longest stint they expect. They got it wrong due probably to a combination of higher race pace loads and mechanical damage suspected to come from the kerbs at turn 14.jjn9128 wrote: ↑05 Aug 2020, 11:05Silverstone is also changing the Beckets/Chapel kerbs to prevent cuts.
On loads Pirelli only have the data teams give them to chose the compounds. I know they have data from last year, but for predicting this years behaviour they rely on the teams. The fact the loads were higher than expected suggests the teams have been holding back on their data.
Just wondering. Wasn’t merc suspected a couple of years ago of applying some tricks to suppress the working pressures of the tyres, while still passing the prerace minimums?
That was dealt with by a change in how things were checked by the FIA. None story. Move on.
But Kvyat's right rear failed, and the kerb you mention is on the left side.Just_a_fan wrote: ↑04 Aug 2020, 17:32
Doesn't really help if the failure is the shoulder due to mechanical damage. It appears that there was damage caused by the drivers running off the track on the exit of Becketts at the start of the Chapel inside kerb. The kerb has been shortened so the drivers would normally have driven on to the kerb there last year but this year they were running across the edge of the tarmac. If that's the case, the simple solution is to put the kerb back, or tell the drivers not to drive off the side of the tarmac there. If they do, it's their problem.
That failure has been found to be a mechanical issue with the car. Something was rubbing which caused the wheel rim to fail and so the tyre deflated. That would have happened no matter what tyre was used on whatever track. A team-caused failure.Shrieker wrote: ↑06 Aug 2020, 21:08But Kvyat's right rear failed, and the kerb you mention is on the left side.Just_a_fan wrote: ↑04 Aug 2020, 17:32
