Does anybody know how much weight the tyres lose during a long stint like Russel did? And when compared to a 20-lap?

[–] Ragglemcsnics@lemmy.world 2 points 3 months ago (2 children)

Definitely not 1.5 kgs worth.

[–] Rapidcreek@lemmy.world 10 points 3 months ago

That would be 400 grams per tire. Not an unreal number.

Why "definitely", please publish your info? Pirelli disagrees with you.

OK I found it myself : https://us.motorsport.com/f1/news/were-russells-worn-tyres-the-cause-of-his-spa-f1-disqualification/10640096/

β€œWe expect that the loss of rubber from the one-stop was a contributing factor, and we'll work to understand how it happened.

β€œWe won't be making any excuses though. It is clearly not good enough and we need to make sure it doesn't happen again.”

The missing weight of 1.5kg may sound like a lot, but we are only talking about 375 grammes from each corner.

And as Pirelli head of F1 Mario Isola has explained, that is well within the boundaries of how much a worn tyre loses.
