Physics Creating tyre wear profile

[Ben Lee]

Hey,

I am trying to learn about tyre wear and creating a tyre wear profile for a given compound. I have taken a look at some of the LUT files already and whilst I can usually work out most of these type of things, these files really stump me. This is from one of the LUT files...

0|99.50.3|1000.6|1001.0|99.52|964|958|9411|9212|88

How do you read this stuff?

Thanks.

Open it with notepad++, it will display it in a much more appropriate and intuitive way.

That example above is supposed to be this:

0|99.5
0.3|100
0.6|100
1.0|99.5
2|96
4|95
8|94
11|92
12|88

vKM on the left, wear mult on the right. Use the physics app (or one of the other dev apps that show it) to monitor your vKM and extrapolate from there in laps or real KM etc how you want them to wear.

Thanks Gary. It gives me a good place to start from. I get it now.

Hi Gary,

What are these apps you mention?

Also in relation to the above figures, what happens after 12|88

I presume the tyres wear down past the 88% mark to 87, 86% etc, so how does the game work that out?

Thanks!

Car Physics App:

Or Tyre Debug App:

I have no idea what happens after the last line in the lut, i would assume it just stays at that value, but I don't think you would ever reach that far anyway before changing tyres (ie you just make the lut project further than you would really ever need)

what's the meaning of vKM can you explain this

what's the meaning of vKM can you explain this

it means virtual kilometers, it's the distance the tire has driven while accelerating hard (any of steering/throttle/braking). As far as I know at peak traction you get 1km per 1km driven (eg. if you were on a circular skidpad), and then above/below that it's proportionally more or less (so if you sit still doing a 300km/h burnout they'll wear out quickly since it's both moving fast and way above ideal slip).

My semislicks_rear folder like this
0|100
0.1|100
0.2|100
0.3|100
0.5|99.5
1.0|99
1.5|98.5
4|98
10|80
11|70
What does the left side mean?
I want to low speed low stability high speed high stability

This is unrelated to speed, the numbers on the left are related to the distance the tire has been driven.

in kilometers? Like the car travels 0.1 kilometers car has a 100 wear ?
How do you adjust the handling of the car? Do you have any suggestions?

 

[Stereo]

It's not kilometers, it's virtual kilometers. It only counts up when the tires are sliding.

If you want changes with speed you should probably adjust the aero balance.
