I believe that the factory wheels on a Pioneer have different offsets front to back. If this is similar to a rhino you can order the rims with the correct offsets to make them run true (in the same track). Does anyone know if this will work for the pioneer as well? I am looking at going with bighorns...most likely 26s or 27s. Once I get it home I can do some measuring but I am anxious to start ordering parts!
