And what are they getting for Germany, an untested kevlar belted tyre that has to go on the right way with pirelli limiting pressure and camber?

I think so, that should sort the men from the boys providing the whole lot don't explode.

Good thing Mr. Chubby isn't driving in F1 anymore then: could you imagine the amounts of lard and half-digested burgers the marshals would have to scrape off the circuit???

Mercedes are the latest to do it, only recently tried the trick. Ferrari do it. Not sure beyond heat. I read somewhere that the teams that do it are the ones that had the failures........but that doesn't account for Hamiltns previous blow out when his gear box was damaged, that was before they were doing it.

IMO tire flipping was not relevant at Silverstone. It's benefits are in temp management from non-lateral (forward/backward) loads - as you would see at Monaco.

The tire that blew on Lewis's car was NOT flipped. Ditto on Fernando's car, can't get conclusive proof on Felipe's car as I can't find a clear enough shot prior to his blow-out.

Anyone trying to defend or say the track at Silverstone didn't contribute to the problems experienced is crazy. Driving over such a sharp edge with the forces going through those tires and pushing sideways into that edge would absolutely cause damage.

Why did they build them that way in the first place?

Good find. But the drivers didn't start driving over the kerb this year, so there is an inherent weakness to the Pirelli design that's causing that. Perhaps the reduced PSI the teams were using is also contributing, but I don't think there's one thing that was the problem here but more a perfect storm situation.

Let Stonemonkey in there with a grinder and a couple of six packs over the weekend and problem solved.

They flip them because of the nature of the steel in the belting. That's why you only see the rears flipped. The fronts have kevlar not steel belts. The steel, by its nature has a "alignment" and the heat generated is higher when the alignment is facing one direction (the supposed correct direction). All teams are aware of this, it was/is very well known in racing when using steel belted tires.

plus a hefty remuneration in hard cash

Tires are simply being pushed harder, but it is absolutely clear an edge of that magnitude and sharpness will cut into an F1 tire. I'll bet that is changed for the next race, as it should be.

I know - my question was about the curbs though.

So the fact that Mercedes didn't use the well known trick in Monaco means their win had nothing to do with the testing? Somebody go tell Horner.

No, if you look at the image posted Mercedes did use it at Monaco and did not use it at Silverstone

Here's the kerbs in Canda, one by the wall of champions, and the other by the hairpin. Nicely sunken in.
