Hamilton.......

As for the penalty points system...........

They showed clips from the 1971 Italian GP won by Peter Gethin whom I had never heard of, he came from 4th on the last lap to win, and the first four over the line were separated by 0.18 secs with 12 retirements out of 24 starters. Hamilton won by 26 secs.

It was the fastest F1 race of all time at over 150mph, until Schuey in 2003. Thems wus the days.

amazing what a safety car can do to bunch a pack up

If you inflate the tyre fast enough it will generate heat due to compressing the gas. Check the pressure straight away and in a short while it will be slightly less.

Would imagine they use nitogen. Its more stable and if there is a fire its safer.

Would much rather watch the Ginetta Juniors racing these days,

Why have 0.001mm-precision components hurtling around on 4 contact patches made of compressed dinosaur, variables, and vulcanised incompetence.

Ban tyres completely for 2018 and see what the teams can come up with instead.

Rails. Scelextricz was always fun & it's an easy was to make them fully electric.

[kerryxeg]

There are quite a few weird issues with the whole pressure debate.

What exactly was the new minimum pressure rule - ie was it just a pressure or was it a minimum that should be observed in all conditions?

I can't believe the FIA did not consider the impact of conditions that might affect a pressure measurement.

How can it be acceptable to have "officials" wandering around cars on the grid measuring or unknowingly adjusting tyre pressures?


What I did find interesting was the Mercedes management reaction to the issue. Some interesting decisions and team dynamics at play.

Well, there would be the same amount of overtaking. I can't see a disadvantage.

Is it possible to use pre-heated gas to fill the tyres?

Possible, but then you're only changing the start point. And different cars in different configurations will heat the tyres differently. It's fairly clear that what needs to happen is a properly proscribed framework for when the pressures are checked and for that framework to be robust enough that it doesn't allow them to get clever and run them under safe pressures at any stage. I mean jeez, they have live pressure telemetry - why not make it mandatory to have that channel open to Pirelli at all times and for them to independently log it?

[graeme]

Pre-heated air would be less dense so you'd need more of it to increase the pressure in a fixed volume by the same amount.

The end result would be exactly the same.

I think.

The tech regs suggest pre-heating the inflating gas is prohibited. Though the brakes are effectively employed as 'tyre heating devices' when the car is being driven, but I'm assuming that's permissible as it's not their intended/primary role (same as the winglets on the brake ducts).

12.7 Treatment of tyres :
12.7.1 Tyres may only be inflated with air or nitrogen.
12.7.2 Any process the intent of which is to reduce the amount of moisture in the tyre and/or in its inflation gas is forbidden.
12.7.3 The only permitted type of tyre heating devices are blankets which use resistive heating elements. The heating elements may only act upon the outer tyre surface.

Whilst the change in minimum pressure is obviously for safety, it also mitigates negative PR for Pirelli.

I thought the whole idea behind nitrogen is it is perfectly dry and stable

[robin]

Presumably even if you fill with pure nitrogen there will still be air in the tyre and thus moisture.

[BiggestNizzy]

Wish all the tech available to Pirelli and the teams I expect I was deliberate. They are not using kit from Halfords.

[mckeann]

Presumably even if you fill with pure nitrogen there will still be air in the tyre and thus moisture.

There will always be air in the tyre before you inflate, but pure nitrogen will have less than 0.5% oxygen and will be dry down to past -50 degC. I guess it depends how much the initial volume of air pollutes the nitrogen

Sniff.....
