I'm looking to mod the tires in game. Is that possible? If so what does the modDesc.xml format would look like? I was thinking it would be a package so I have:

<type>Packages</type>

<Tires>
<Hadron path="data/vehicles/_shared/physics/hadron/Tire/seta.0.hadron"/>
</Tires>

any help in this matter would be great.

You have to go into the _shared/physics folder that you saw and start tinkering from there. There is a dev file as to what each parameter does. As far as I am concered, S4 used a base tire that then modified for each car/class linking back to an original file. I haven't gone that deep as I don't know vehicle dynamics, which is important for understanding these files. Hope it helps.

Yeah im familiar with the file and already made some changes making the physics feel really really good. Doing my research i got my answer. im hoping i get start a dialouge with the devs.
