Well the good news is this is a simple object to UV. Just do a planner map for the front and back face and a cylindrical map for the inner and outer rims.
I can't help with the digital painting of the maps though as I am not a very good digital painter but here is a video to help you with laying out the UV's. This technique will work for any tire like shape.
