Lol, how'd they get away with that?

I'm pretty sure I noticed that soon after the start. I'd say it was contact with another tyre/car that caused it.

Contact with another car caused one tire to look like a prime and the other to look like an option?

This is strictly speaking against the rules but it really shouldn't be. Back in the 80's drivers could run a different compound on each corner if they wanted to.

dunno if im wrong but wasnt vettel on hard at the rear and soft at the front back in china 2007? i remember the commentator pointing it out

you can see there liuzzi using soft at the front and hard on the rear

its illegal and he should be disqualified based on it.

It's caused by contact- it takes very little to remove what is just a sticker on the tyre. If you look at Senna after the crash, his tires are the same b
And it's impossible to get away with that- the FIA monitor tyre use very carefully.

Lol, I like how it says "Vettel: Leader" when he was in 7th! As for a sticker, are you sure? That looks like silver/grey to me, not residue from a sticker.

Nah it's from contact. Watch the 2011 season review and when massa and Hamilton collide in india the same thing happens to their tyres

How did he get away with this

i don't think that is because of contact. if u see the details on the tyres, both have similar pattern, front and rear, just different color. if it is because of contact, the pattern of the tyre should be upside down.
look at the picture below. the patterns are the same. that's clearly a soft and hard tyre.

Hmm, if it's just stickers, I wonder if anyone has slipped a change-up past the FIA?

If a team were to make & bring their own tires, they could swap them with the FIA ones (with the stickers transferred) and get away with better performance. Since Q3 qualifiers usually carry one set of used tires over to the race, they could keep those to the side as returns for the substituted ones at race end, so they'd show wear instead of being new when the FIA expected worn tires. Or can the race stewards positively identify them (RFID, photograph them?), and then check those are the ones on the car at the start? Even then, high tech identification could still be circumvented, I believe (come on, I watch James Bond flicks, of course I believe).

With the tires being the problem they are, I wouldn't bet against someone having tried this yet. Would any of you?

I actually like that idea. Let the teams decide if this helps them balance out their car. Unless the FIA actually want the crashes/mix-up in standings from rears or fronts going off independently...

Pirrelli scan every tyre and they have to be used in sets .

It would be impossible to pull one.

Nah, I was saying it was possible/feasible to swap a whole set. If their scanning system were cracked, you could make your own "barcodes", so to speak.

I think the suggestion is that Vergne made contact with another drivers tyres which then smeared black rubber over the top of the yellow logos which is why you can barely see it and it appears almost grey.


It's not a transfer from another sticker, it's a hidden yellow logo.



And this would be why you can hardly see the word Pirelli as opposed to if it was actually a different tyre.



IE - It's a SOFT tyre with it's logo smeared and hidden in Black rubber and not a Hard tyre...

I believe it was contact with one of the Force Indias in the first lap - probably left a black rubber mark over the yellow paint. Can clearly see the Rear RHS tyre with yellow markings halfway through lap one - but a flash past the cameras and the Rear LHS tyre already looks darker. Pretty sure you can see the Toro Rosso & Force India touch when onboard with Webber in the first lap.

Senna's rear tyres looked like that as well, but there were shots of them having yellow paint earlier. I'm fairly sure it's the same case here.

How Do you explain that the tyre was gray on both sides of the tyre. I spotted the tyre issue during the race. I am fairly certain it had no yellow color on the inside face unlike all of the other tyres on the car.
Be keen to some vision from the race to confirm it.

Here is a better image:


Apparently they were the soft tyres, but they had the wrong markings painted on them.

Just watched the race again - when Vergne was forming up for the grid and performing his burnouts en route to the grid position - he clearly has a yellow marked tyre on the rear left.

Pic 1 - Startline Burnout forming up to grid: Picture 1 - Click to view
Pic 2 - Contact with Force India: Picture 2
Pic 3 - Yellow paint scrubbed off following Turn 6 contact: Picture 3

Hope that solves the question, and certainly not incorrectly painted tyres as suggested. Vergne did 10 laps before his first pit stop, all pictures above are on Lap 1 & contact was made with Force India through (I believe) Turn 6.

Lol, I asked this on Twitter to PH and another senior Pirelli engineer for Torro Rosso. Vergne must've banged wheels with another car to force the paint to fall off (change colour). He definitely wasn't mix-matching the compounds.

Jean-Eric Vergne ‏ @JeanEricVergne

Hi everybody, just to clarify this mix tyre story, it was well a soft tyre but the yellow marking went off after a contact in the first lap.
