Quote -  I think you've got it!  

nooo... no I don't... somethings missing...  OK, i am in the vertex modeler, select the areas and created 3 shader domains (sidewall 1&2 along with a tread) after that nothing works.. I go into the UV section, add a seam across the tire, and all I get is total gibberish when I go and unfold...  so what step am I missing here...?   watched all the vids and nothing shows me ( that and the interface is totaly diff in this area between 6 & 7, but I got the gist of it)...
