2025 Spanish Grand Prix - Barcelona-Catalunya May 30 - June 1

Do we know who has how many tyres of each kind left ?
Is there an official website where we can look up how many tyres are used up / left over, for each driver, from his allocation set, after each session ? I have seen members fastidiously posting excel sheet snapshots (which I think they are maintaining personally) , but I am surprised I haven't come across any 'official' source of info for the same.

There is not. Pirelli sends out updates like this to the press in the evening, which usually end up on (for example Albert Fabrega's) Twitter:



On German Sky they occasionally talk about the tires left during the sessions, so commentators seem to have access to lists updated live, but as their information often is incorrect, it could also be something they create internally.

So the only way to have reliable information quickly, is to keep track yourself.

Edit: so yes, I usually do this myself, and post the sheets when it seems to be of interest.

Thank you very much for doing this for all of us.

Let's say we are talking about people who are more likely to be in Q3.

1) lets say 4S needed for Q.
2) lets say 1S used up for final quali runs tune-up in FP3
3) a) Non Mercedes/Williams
that leaves 1S,2M,1H - which of these will be 'used-up' in FP3 for long runs ? This "FP3 usage" can have big repercussions for the race, will anyone risk not keeping H for race ?
3) b) Mercedes/Williams
they have one M less, but one S more, so most likely that they aren't going to burn their sole M and sole H tyres in FP3. Or will they ? and risk taking 2S and only one out of M or H into the race ?

FP3 tyre use will be fascinating to watch.

it's not allowed, 1xH and 1xM need to be kept for the race.

So they could of course use it in FP3, but it makes no sense, as they still need to return 2 other sets then.

why would they need a hard AND a medium for the race? The rule is to use 2 compounds during a dry race. If you use soft, you can use hard OR medium.

I second this

why would they need a hard AND a medium for the race? The rule is to use 2 compounds during a dry race. If you use soft, you can use hard OR medium.

it goes down to a different rule:

"Two (2) sets of the mandatory race specification(s) may not be returned before the race. For the avoidance of doubt, if there are two (2) mandatory race tyre specifications, one (1) set of each specification may not be returned before the race."

The "mandatory race specification(s)" are always lined up in the Pirelli event notes before the weekend:



And as far as I can remember, they have never not been medium & hard.

[Vettel165]

I would start on the medium and then just go hard in the middle stint and then again on medium on the last (MHM). If there will be a 2 stop race of course..

Very informative. I wonder though, how did teams run S-M-S last year? Then I assume Hard wasn't a mandatory tire

they are both mandatory to be kept for the race, but not to be run. Only one of them is:

Unless he has used intermediate or wet-weather tyres during the race, each driver must use at least two different specifications of dry-weather tyres during the race, at least one of which must be a mandatory dry-weather race tyre specification

Mandatory in the sense that you have to have it available for the race, so you can't sacrifice both hards to save an extra of another.
You don't have to run it in the race.

Thanks both of you!

[Sergej]

so all the top teams out on new medium means they are committing to do one stint on soft ? given it'll be a two stops race...

Sauber seems to have stepped up a bit with the upgrade this weekend. Although they've mostly been "good" on flowing, hot tracks the past couple of years already.

[Sevach]

The Mercedes wing still has quite a bit of play.
