2024 Las Vegas Grand Prix - Las Vegas Strip, Nov 21 - 23

[FW17]

I still don't think it is illegal if the use humid air to fill the tyre.

It was made illegal years ago

Think that was for the liquid form of water

[JPower]

Verstappen and Sainz having new ICE units might be a big plus here.

This track looks slam dunk McLaren, especially with their newest high efficiency floor and low track temps (which takes away Ferrari's tyre deg advantage).
AFAIK, McLaren have matched (possibly exceeded) the big advantage Ferrari held in slow turns and low speed exit traction.
McLaren also hold advantage over Ferrari in medium speed and high speed corners.
The only place Redbull (even with Verstappen's one race old engine) might ace over others is T10 and T11 high speed turns, but it will be very marginal and won't contribute anything significant towards laptime.

I still don't think it is illegal if the use humid air to fill the tyre.

From the 2024 Technical Regulations, 10.8.4:

a. Tyres may only be inflated with air or nitrogen.
b. Any process the intent of which is to reduce the amount of moisture in the tyre and/or
in its inflation gas is forbidden.

That's pretty hideous.

Reduce = Increase ??

Glad I'm not the only one that noticed that and found it odd.

That's pretty hideous.

Like a 90s kid doing a really bad job with new felt-tip flames on his hotwheels racer

So you can add more moisture then…?

Ha! Looks like flow-viz.

If you're reading that particular rule strictly as written, then I don't know how the answer is anything but "yes". They specifically say "reduce the amount of moisture" instead of "change the amount of moisture" and make no mention of "increasing the amount of moisture" being forbidden. Now, there may be another regulation or technical directive that deals with that since Red Bull tried this back in 2016 (IIRC from what was said in the thread about this), but going just by this particular rule it would appear to be allowed.

Indeed. Isola, AMuS and formu1a Uno including talk in the paddock has all claimed it's plainly illegal in the regs so must be dealt with elsewhere like you say. It's not legal though, as has been suggested in this thread

It appears the technical directive put in place when Red Bull discovered this loop hole in the rules outlaws this practice, though I don't have the technical directive to quote directly.

Just added the story below which corroborates what the other sources you listed are all saying, "this is not allowed."

https://www.motorsport.com/f1/news/fia- ... 0stewards.

It is understood that the idea of adding moisture to tyres has been outlawed for many years through a technical directive that the FIA issued previously, so anyone found to have been adding liquid in this manner could risk being reported to the stewards.

Edit: https://formu1a.uno/en/f1-tyre-moisture ... nterlagos/

The TD reads “any modification to the inflation gas composition or moisture content aimed at reducing on-circuit pressures is not permitted. This includes increasing as well as reducing inflation gas moisture content, and the addition of any solid, liquid or gas not permitted for this use in the technical regulations.”

So in the TD they added the term "increasing" to the already existing language that mentions "reducing" moisture content.

[TimW]

It says you can only inflate with air or nitrogen, so not with water.

'But putting water in is not inflating'.... and there is the reason for the TD.

[AR3-GP]

Did anything come out of those rumors about McLaren messing with their tires?

FIA and Pirelli have been checking tyres since Mexico, nothing has been found.

The tires were not checked in Mexico. They only started checks in Brazil.
