About those tyre temps…
Nobody notice how tyre CORE temp is always higher than the outside temp? Nowadays my tyres are above 102 degrees after couple laps, while my surface temp is 68 degrees or something, and even if I bur...

@Iceman038-NL Actually quite realistic. The core temps are higher because heat transfer from brakes.
Surface temps rapidly cool on straights once car has full traction and tyres are not under lateral stress.

- @ScarDuck14 Exactly! Although the surface temps cool down too quickly, like IRL no temperature will drop 30° within a second to then completely stop changing but thats easily fixable for the next game
the question is always the same where are the explanations that indicate what affects the temperature? what can be done to make them cool? why don't they give more detailed explanations but only general information that is useless? this also takes the height to say you adjust but you don't know how much you actually know by lowering by raising ..... it is forcing the pilot to copy other people's setups without even being sure that it is right for your style.
- @ScarDuck14 Where do you base that on? The tyre core temp will never be this far off (+20 degrees) of surface temp, that’s not possible because then the tyre will get blistering. And blistering happens when the INSIDE is hotter than the outside, and the tyre will start falling apart at these levels of difference. You forget that the brakes heat the rim first (which is also 18 inches so more surface to heat, and F1 brakes can dissipate heat way more faster and efficient than road cars) so you overestimate how extreme the tyre warming from braking is (since rear brakes are almost non existent since the mgu-K does a lot here with engine braking brake migration)
And a tyre will cool on straights yes, but not as extreme as this. The moment I do a burnout and stop, temps are already going DOWN, while in fact the surface at that moment should still be going up seeing rubber gradually heats, especially towards the end of a burnout. It should go up extreme, and when I stop, it should slow down but still go a bit up until the max.
I’m a very extreme tech guy so I do understand the workings and effects on braking and friction on surface, but you forget a lot of other factors in play which are of a lot of influence on temps.
And whats happening here is nowhere near realistic.@Iceman038-NL what would you consider a good, "ok, that's a wrap" answer? I'm only on my phone right now and about to go on a trip for the weekend.
iRacing has their own tyre model based on a theoretical approach instead of an empirical model like most simcades out there. Meaning they work on materials, hysteresis, load and temperature sensitivities... All that jazz, they work on it all so that their physics engine has to simulate a realistic tyre model instead of feeding it a look up table and have it connect the dots.
iRacing's Mercedes W13 was made in partnership with Mercedes F1 team. You can look up the details on their Downshift podcast with James Vowles on how the project developed.
Not playing games here, mind you. Genuinely love these topics. May even have something at hand like a source or link to someone spilling the beans on Beyond The Grid or the like in my notes, but right now this toilet quick post is all I can offer.
That fluctuation is realistic.
Why cant F1 23 have that sort of tyre temp and tyre wear, they are just scipted to me at the moment and the last lap thing fastest lap for all AI cars come on this is childs stuff has to change drastically next year.
@Iceman038-NL Blistering happens when the core temperature is too hot for the tire construction, meaning way above the operating window. Blistering is, when due to that heat the inner layers of the tires soften and crack open. It does not have much to do with the surface temperature.
And if you mean graining, then it's quite the opposite. Graining happens when the surface temperatures reach high temperatures compared to a cold core temperature.
And either way, the fluctuations may be too quick, but they are realistic.
