Tyre degradation

When I create my strategy for a race, I obviously keep in mind the tyre degradation over a lap. But it seems off a bit, as I can see tyre degradation of Softs is 8% for instance, meaning 10 laps on them would get them down to 20%, but during the race, the tyres usually degrade a lot less, when my drivers go in, they are at roughly 40%.
How does this work? And what would happen if I would tell them to do 14 laps on the Softs and then end up with them going down to 0%? Would the car break down, or would they pit automatically?

Also, it is not really clear to me what percentage of degradation is best to change tyres, all I know now is that the percentage goes red when they drop below 50%, but other drivers seem to continue a lot longer on the same tyres.

You have the right idea for figuring the number of laps a set of tires can go. But you should know by now from looking at you past race data that tire wear is not linear. So while the wear starts at 8% for first lap it 2, it decreases making it possible to get closer to 14 laps.

As for what happens when tires get to 0%, they blow out. Your car rides around very slowly and pits for new tires. Hopefully you have enough fuel because I assume fuel consumption would go way up on that lap. Running out of fuel is race over.

Lastly, there is a slight performance drop-off at 50%, and a huge drop off (cliff) around 20%. You have to experiment with the different compound to see where it truly is at.

You have to weigh the slower lap times against the time lost for a pit stop to decide when it makes sense to pit

Thanks, that explains a lot. So does the wear count from the current state then? So the first lap = 8% of the 100%, the second lap would degrade them by 8% of 92% = 7.36% etc? Although this should still be off a bit, as it "should" be a continuous process, not just counted at the end of each lap.

Yes, roughly that's it and as you mentioned it's a continuous process. Additionally there's some rounding involved as well so if it tells you 8% the starting value could be anything between 7.5% and 8.49%.

Dont do it, you will end up racing like me and I can tell you it's not very fast. :D

I calculate my tire wear down every race. I see times drop when tire condition drops low (40-0%). Mostly i race secure and wear them down to 20/15%. In my competion i feel tho that its to easy to win by wearing them down to almost 0 and thereby taking more risks. i think im racing on the edge, some race over the edge and then get rewarded. And i do have one of the best develeped cars and best trained/experienced riders... Is there anyone els that experiences this?

My cars start getting slower once the tyre goes past 50% health. That includes Inters & wets.

Tyres Annoy me

SS 6 Laps
S 12 Laps
M jumps up a lot 25 instead of 18 Laps
H jumps up more again 33 instead of 24 Laps

It's not counted for in SS or S so why is it took into account for M & H

Count backwards
H 33 Laps
M 25 Laps is -8 from hard
S 17 Laps is -8 from medium
SS 9 Laps is -8 from soft

Ok I just confusing the thing lol
70% of 33 = 23.1 that's why I said Hard tyres jump up 33 instead of 24 Laps

Without a decimal point, 3% on hards is between 3.0 and 3.99 that gives around a 30% margin of error.

Because wear isn't linear, after 33 laps you will have somewhere around 26% to 36% left and not 1%.

If you have race data, you can use regression to find the more-or-less exact value of tyre wear under racing conditions.

Don't like the sound of still having more life.
Surly 4 stints of SS should be equal to 1 stint of H
3 stints of S = 1 of H
2 stints of M = 1 of H
It's meant to be simple lol

Belo debate

Nope! Don't like it, using over 50% tyre life is too slow.
