Albert1960 - ok, so you asked about tyre pattern.. It was designed for a 2 mm thickness because of original tyres has also deep pattern.
You can made them by these ways:
1. As Toudi_sk wrote, you can make 2 mm cardboard (sandwich) by layering of 160g or 200g papers,gluing with Pritt Glue stick or similar quality glue stick. It is very good for cutting and the edges after cutting are also fine. I used this method.
2. You can use 2 mm cardboard or 2x1 mm combination glued with stronger glue, the egdes aren't so good as like as in previous way so you have to treat them.
3. It's possible to laser-cut the pattern, as are made for example tracks for tanks.
I hope these information will help, if not then let us know
