You can find parts for tracks under "Tyres And Rims - Special"

checked, but there's no tracks.

The parts are there, you have to build them with 3873 or 88323 or are you talking about any other tracks?

See the post...

@bricc tank tracks are available in the library under reference 3873 and 88323 as sealund mentioned. Just type “tank” in the library search field and you will find heaps of models that people designed using them. If you are after another type of tracks please specify the design id so that we can direct you.

ok thanks.
