Oh my gosh, this was a nasty job. The old rubber tires were so gooey and just pure nasty. I started scraping the gunk off but after awhile I just gave up. Then i went and bought a new wire wheel for my grinder.... oh yeah... it was nasty as black rubber crap was flying everywhere but still faster and less painful than scraping. If I ever buy a new band saw I think ill just change out the tires from the beginning unless it comes with the urethane tires. Needless today I bought Carter urethane tires this time and cant wait to get it up and going. So many parts to clean makes the wheels the easiest part however. If anybody is up for new tires and has never done it before I have to suggest using a wire wheel on a grinder.
