Why do F1 teams scrape their tyres?🤔

Far to often we've found ourselves watching videos of an F1 tyre being scraped for hours on end!
The reason behind the scraping is simple, to clean the tyre and gain data from it! By making a clean patch on the tyre the team can gather accurate data on degradation and wear.

TL:DR it tastes very yummy

[@core_russell3869]

Knew it

[@thequinlanshow3326]

Yummy yummy yummy I got macrorubbers in my tummy 😋😋😋😋😋

[@NicoPicoPlays]

yeah i did wonder and now i know thats for this

[@toozydude2]

Is this layer intentionally collected after the finish line to avoid further wear? Ie why they always say “pick up rubber” after the finish line.

[@damionlee7658]

The reason used to be about the minimum ride height and weight measurements in parc fermé after the race. One of those things where it shouldn't be critical, but could just scrape you through scrutineering if your car was borderline. At this point, I do wonder if it is just a case of "That's what we've always done".

[@toozydude2]

@@damionlee7658 thanks! Interesting! but not to protect the tire from further wear and causing inaccurate wear measurements then? I guess 1 slow lap after the race isnt going to add much additional wear even if they didnt pick up rubber.

[@damionlee7658]

@@toozydude2 I wouldn't swear to anything (as open as F1 is, there are still more secrets than anything else). I would say you are correct that the in-lap at the end of a race would cause only negligible wear. Plus other tyres used throughout the weekend are probably more important than the last set used.

[@Flowersheepy]

@@damionlee7658that’s not the main reason, the main reason to why they do it is so make sure that they are over the minimum weight requirement, that’s why the engineers say “pick up rubber”

[@damionlee7658]

@@Flowersheepy did you read my comment properly? I'd like to draw your attention to the words "Weight measurement".

[@trishchepish]

And this gets in my mind the image of old F1 mechanics making hand cuts in the tyres for wet races/practice sessions/qualifies. Those were old days where they had to use their brains. Now they use a similar method to analyzing tyres

[@nateisdabest]

So pretty much, they are just cleaning a patch of the tire in which the teams and Pirelli can measure how worn the tires are so they can predict what kind of tires they would need to use. This has been done for at least a decade in NASCAR already where tire wear is measured and sent to Goodyear to get tire data and potentially make a stronger tire in some cases, ahem Texas 2022.

[@nikosscharp2918]

Its not like F1 started doing this yesterday

[@sedwars3616]

f1 has also been doing this for decades

[@riversarcadereview385]

perfect explanation

[@garethtcollins]

Think you mean discarded not disregarded!

[@matthewtgg8491]

They do the same thing in nascar

[@narutoneoji9611]

So the teams and pirelli?

[@EdthePlumber]

Always though it must take hours to scrap the whole wheels, make more sense it just a small section

[@gigadog2247]

My money don't jiggle jiggle it folds

[@wasylbakowsky5199]

'disregarded rubber', lol...discarded rubber e.g. marbles etc.

[@Skyl4rarts0]

Um i just had an chocolate ice cream with chocolate chips and thinking why does it taste so bad💀💀

[@meaty8887]

why not have the tyre manufacturers create racing slicks that doesn't degrade in the first place and stay the same shape from start to finish?

[@wasimshahzad1988]

😊

[@maxzifyfn7820]

naww I thought they reused them 💀💀

[@TryingMrJames]

Don’t Pirelli scrape the tires?

[@RectangularSquare1998]

I thought so they could use the tyres again

[@SmolCloud]

can we please start making tyres from something non toxic, im so sick of pollution

[@J0LL1B33]

Anyone else getting the urge to just eat the scraped off rubber?

[@universpro7741]

If they scrape it, it hasn't worn off

[@jeffreytenthije]

And first collecting all the marbles, worn off balls of rubber off the racing line, the mass of gum like layer, makes it so the car is a bit heavier, to comply with the weigh in of the car at the FIA

[@__DeezNuts__]

They scrape it so they can reuse it
