My local dealer actually keeps a jack plane on hand specifically for shaving that area down on tires used for sumo conversions.
Post a pic of the area and we can go from there.
Not sure there should be LC8 chain rubbing on the back tire. Especially with a 180/55, since it is stock width. The comments about the 450 are accurate and I, too, shaved to keep the chain off the edge of a 450SMR tire. The 950 has a wide swing arm and plenty of space for the chain and tire to live without rubbing. I'll double check my pics for a different story.
