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.

yeah i did wonder and now i know thats for this

[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

[toozydude]

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.

[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.

Think you mean discarded not disregarded!

[EdthePlumber]

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

[gigadog]

My money don't jiggle jiggle it folds

[Skylrarts]

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

[SmolCloud]

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

[meaty]

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?

[wasylbakowsky]

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

[Just_a_GT]

I thought so they could use the tyres again

[universpro]

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

[JLLB]

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