F1...

[Mr Momo]

The F1 forum after the GP showed the kerbs at turn 4 - it was blantantly obvious how the punctures occurred - a 'sharp' edge on the inside of the inner kerb caused by the kerb being raised about an inch. There was a lot of evidence of rubber on the raised edge
To hit it the inside tyre needed to be maybe 6 feet off the track - and the outside tyre probably just on the course.

Throughout the race the engineers were telling drivers to stay off the kerbs - they didnt - the tyres burst, not sure how Pirelli are to blame

I'm with this camp - drivers should have stuck to the track - anything else is cutting corners to save time, but taking more risk.

Sidewalls are not meant to see that kind of sharp change of height.

OK it was Marussia I was with, but pretty quickly after the punctures started, the team increased the tyre pressures on those waiting to be fitted. Don't know what was said by the Pirelli Techs, but the team responded.

Interesting reading in that, especially about running the tyres mounted the wrong way. Explains something we observed over the weekend. Maybe they do know the difference between left and right

Re tyres left on right, they did that back in the eighties, made a big difference, (for the better)
Was on the bbc website about that, that it was not a new idea. (Andrews blog)
After this farce and the extended young drivers nonsense (main drivers getting used) think merc should be allowed to participate.
Pirelli were as responsible - they are getting to test ?

You can always rely on Sniff....

That Pirelli Statement in Full:

A series of different causes led to the tyre failures at Silverstone:

- We didn’t know the cars would be driving that fast.

- Uneven wear caused by too much turning right.

- The teams repeatedly put new wheels onto the cars too quickly.

- Excessive braking, accelerating and swerving about.

- Extremely sharp leaves on track.

- Failure to proceed to approved Pirelli stockist upon kerbing tyres

- We were asked to make sh*t tyres. Stop fcuk complaining when the tyres are indeed sh*t.

Many a true word spoken in jest

with respect, your not a racing driver, kerbs are part of the track, they will get used.

to blame a kerb that's been there for years, on a cct that's probably the most used on the world without issue, is somewhat wide of the mark.

With respect - the choice to use the kerbs rests with the drivers - if as a consequence they have a punture they shouldnt blame the tyres. The teams told drivers not to use the kerbs - they contimued to do so - who's at fault.

Ok so that is perhaps being pedantic we all know they are going to use them but it is the extent that they used (this particular) kerb that caused the issue , but its been said many times before by better drivers than you or I - if there were barriers there instead of kerbs they wouldnt use them

kerbs are part of the track, you only have to have 2 wheels inside the white lines.

[BiggestNizzy]

I am suprised pirelli don't state min tyre pressures / what wheel they are to go on then force it as a safety issue in a similar vein to what Michelin did in the USGP05.

Thus leaving any liabilty with the teams.

except touring car, where the grass is part of the circuit

One of the worst aspects of modern F1 and the redesign of tracks, is putting in chicanes that can be driven straight across with no obstacles, and no penalties as long as you do not gain a place.

They are put there normally to cut the speed back, and there is skill and judgement in taking them at the fastest possible speed along with not coming off, so now just drive into them and it does not matter if you misjudge and go in too fast, just drive straight across with no danger of damaging the car.

Load of bollocks.........

Agreed.

One of my pet rants has been resultant short-cutting due to the flattening of kerbs over the decades. Flattened for safety reasons of course. Watching YouTube clips from the 80s is a refreshing reminder of how I remember it used to be (eg. Senna qualifying below Adelaide '86 - minimal kerb riding due to height/profile). The BTCC at Croft is pure comedy, where the route of the track/chicane is completely ignored once the floppy bollard is knocked away on lap 1.

Last weekend at Silverstone, cars habitually entirely left the track on the last corner exit onto pit straight. No published stewards warnings. No mention from commentators.

Exactly what came to my mind.

Tbh whether or not the kerbs are part of the track, it's still the drivers choice to use them.

If the boundary of the track is defined by a white line + the wheel track width of a car (ie, you can go outside the line but only with 2 wheels) then the grass is also part of the track.
Would we be having this conversation if punctures or accidents were caused by drivers sticking 2 wheels on the grass and the car letting go?

Drivers are there to score as many points as possible. To score points, you first have to finish.

The cars still looked good then, one front splitter, one low rear wing, and the car looked alive under Senna, wriggling and moving around with small corrections.
