Those tire threads are easy, they were made with 3d max 3.0, all you have to do is model the line thread, make a mirror of it, clone it with the spacing tool, extrude it with a black matte material, and make a render of it, if you wish you can adapt the map to fit the tire with PSP or photoshop like I did, set it as a bump on the tire material, and there you go.
