Off the top of my head you can do what you want in UV mapper, though it may be fiddly. I hope I explain this well because it's making my head hurt. What you need to do it map the whole tread, preferable in a long strip, so that there is each section of tread is the same sixe and shape with the same distortions etc. You can then move each section so that they overlay each other in the UVMap. Then when you apply the UVmap to the model it will repeat the pattern around the tread. I'd probably start my making a cylindrical map with cap, to seperate the tread from the tyre walls (not sure which orientation, whichever is closest to your current map. Hope that makes sense. John
