[Tyres] file ERP
I'm starting to study the tyres file ERP (thanks @P4st3l1ak), having the new C0 compound the code name looks shifted by 1 place, before to make the wrong assumptions, what do you think about @Actuall...
Forum Discussion
Thanks a lot
I have plotted the grip at 0% wetness for all dry compounds against the wear in a single graph based on the info gathered from the table provided by @Nuvolarix .

In this type of graph, the segments are drawn straight between two points from the data obtained, in order to build the curve. We therefore perform a simple linear regression between the two values we know.
For example, C1 has 90.34% grip at 19% wear, and 87.72% grip at 25% wear. From the graph, we assume that it has 89.03% grip at 22% wear.
Is this just an assumption, or are we sure that this is how the game calculates grip?

You also have to calculate into grip the wetness of track (above graphs are for 0% wetness, I think) and tyre surface temp. So it is more of a 4-dimensional graph 😉@P4st3l1akBut looking for tyre surface temperatures needed for 100% grip in C1 compound, if I can keep it between 90-115°, it means that I can gain that 89,03% of ''total'' grip at 22% wear, all of this assuming always track has 0% wetness, am I wrong?
@Meza994Alright everything it's clear, it'll be very interesting working on setups now :D . Just another question:
Let's assume an A and B case considering C1 compound.
Case A) Carcass Temp 108-110° C and Surface Temps 113-115° C
Case B) Carcass Temp 100-102° and Surface Temps 90-92° C
How changes car behavior?Because in my opinion, thinking in a physic way, more °C surface/carcass temperatures, more tyres degrades. I just don't know if there is actually a difference, between A and B case, in terms of car speed, or also other things that actually changes how car behaves.- @Im_Pando In theory it shouldnt make a difference as both A and B give you 100% grip from carcass and surface, however surface temps are only in that range while cornering so on entry you might be a bit low on surface..
Also higher temps have IMO never lead to higher wear ingame but David Greco would have to answer that, i would expect both examples to perform the same way for the most part as otherwise its even more unfair to not be able to set tyre pressure for each compound.. - @Meza994 I think that David can only answer (if he can) to this question, but in my opinion, it would make sense all the work that him and his team made to have more realistic situations, even in strategy, where if you put X psi to tyres, you can use, for example, Soft Med Med as strategy, but if you put another Y psi to tyres, then that values can make you possible perform better a Med Hard strategy
- @Im_Pando Well that scenario you are describing is completely unrealistic as each tyre no matter the compound can have its own pressure, in the game all rear right tyres no matter the compound are forced the same pressure..
Of course it would make sense to have more wear with higher temps but the game is still no sim, temps are way easier than IRL because Codemasters doesnt want all players to sweat too much trying to stay within a good temp window etc. its all simplified a bit, still more realistic though - @Meza994 Yeah but maybe I'm thinking in a too realistic way, but as you said, tyre pressures in real f1 are the same once you start a race, no matter if it's a soft, medium, hard inter or wet ones. I think that it adds also there, a challenging way to understand which strategy fits your chosen starting tyre pressures..
- @Im_Pando But it adds something unrealistic only to simplify things which i dont like, yes its an additional strategic thing to think about but id prefer the real way, but thats just personal preference..
Btw you got it mixed - probably only written wrong way around - in real F1 pressures are not the same for all compounds, but in the game they are the same 🙂 - @Im_Pando Afaik yes! Back in 2005 when they were forbidden to change tyres in the race they sometimes changed the tyre pressure during a pitstop too hahah
I cant find anything limiting tyre pressures in the technical regulations + it wouldnt make any sense, front left may have a different pressure than rear right but for example C5s must use the same pressure as C2s (like in Australia last year) which by my observations have something around a 20° difference in working range, having to use a single pressure for both would be hilarious because one of the tyres couldnt work! Awesome to look at the data for this year’s game. Pretty big change regarding to the surface temps. So when entering a corner after a straight the tyres won’t ever have ”100%” grip for their wear since the surface temps are ~70°C.
Also not exactly tire related but what about engine temps? What’s the optimal window for that?
