Physics How do I update tires on an old mod?

[ssdsdsss]

Hi there, so I'm trying to fix some broken mods. I've nearly finished fixing one, but I'm struggling to find information on updating the tire model.

Currently it's on version 3. I want to update it to version 10. The issue is I have *absolutely no idea* how to do this.

I want to use the DTM 90s compounds. Unfortunately the wheel size is very different from the existing cars using the DTM 90s compound, so I can't just replace them in Content Manager.

So far what I've done is used CM to replace the tires with those from an M3 DTM then manually edited the width and radius in the data file. I mean... it works, but there has to be more to it than that.

So how do I do this?
