Tyre pressures

Is there a list with optimal tyre pressures for the cars in AMS2?
Ive been kinda going off optimal irl pressures or whatever I can find online at that moment, but a list with all cars would ofcourse be ideal...

 

You can find some values for Project CARS 2, but I don't think they're particularly relevant for AMS2 given Reiza have pretty much remodelled their tyres.

In practice, you should target a linear distribution of temperatures between I-M-O (with higher temperatures on the inside) with a ~5 C split in the rear and ~10 C split in the front. The optimal hot pressure is whatever gives you that optimal contact patch.

 

Thanks, but I knew that (more or less.
I was just wondering if theres a list of tyre pressures to aim for in different classes.

I think I found the one for PC2 but like you said it might not transfer to AMS2.
Tho I think they would be aiming for ingame pressures to line up with irl pressures being a sim and all?

 

The question is flawed because you should not be targeting a particular pressure, rather you should be looking at the temperatures and optimising the contact patch geometry (things that really matter for grip). And no simulator outputs values for tyre pressures/temperatures that correspond 100% with real life. That is the nature of tyre models, they are all imperfect in some way.

 

Ok, but isnt it true that ie GT3 cars run around 1.7 bar which would at least give a solid starting point?

Or do you figure every class out from scratch?

You could try. if you have no luck finding anything.
Try TT in default , 1/4 -1/2 lap take note make list.
Tyres should be at optimal at start of TT

 

Which GT3 car (weight)? What tyre compound? What altitude? What track temperature? There is no single value for an entire class or even a single car, it depends on the track conditions. This is why you need to do a couple of laps until the tyres have warmed up, then make small changes according to what the temperatures look like. The contact patch should be the target, cold pressures the tool to control them.

 

Ambient temperature and altitude are not relevant, we're talking about hot pressures here, not cold. You adjust the cold pressures to arrive at the desired hot pressures for a given tire/car which should always be similar.

For example, the tires used in the GT World Challenge run optimal between 27-28 psi hot, so you aim to be in that window. This is a known value from the tire manufacturer, but of course probably only works for this tire.

In a general sense, since the size of the contact patch depends on tire pressure, there should be a window for ideal hot pressures for each tire, and since this should be a known value in the sim, it should be possible to output it as well. Assetto Corsa for example does that.

 

I get that it's not the optimum in each case, that's why it's a window and not a fixed value. It's a ballpark, so you at least have an idea what you're aiming for. The tires on my road car have an optimum pressure window recommended by the manufacturer.

Like i said, the game knows when the tires have optimum grip, so based on that there could be a calculated optimum window for the user to work off of. Fine tuning is always required of course if you try to get the last percent of grip out.

If you tell me the current stock pressures go up to the optimum window when hot, I can work with that.

 

Your looking far too in depth at this so called perfect tyre temp setting, ACC model.
Drive the car and adjust if necessary, but adjusting pressures isn't a cure like ACC garbage.
Driving style, driving over the limit, setup are just a few, plus the fact that most race series have set tyre pressures from the tyre manufacturers that they must adhere too.(min-max)
You cant just set all the tyres to 27psi and bobs your uncle a perfect car, thats the biggest load of rubbish from ACC that people are now thinking is the new norm .

 

Litterally nobody said any of that but thanks for your most valuable contribution.

I guess Ill just begin at zero and start adding one psi at a time. (Y)

 

Ok I think this anwsers my question.
I thought they all started at a default 1.4 or whatever it is I saw in a couple cars ive been driving the last couple of days.

 

Thanks, thats the thread I found as well.
I think I was probably doing GT1 and GT3 when I noticed those presets were the same.

Ill take a look at the yt vid and see if I can get my temps/pressures right. I remember also having to do this in PC2 in the day so it shouldnt be too bad once I get back into it.
