Well, I got a used Delta 28-276 bandsaw last week. I replaced the trunnions with some beefer ones since the old ones were broken. I was testing the blades i got with it today and the tire snapped. What size tire do I need? I measured the wheel and it was just shy of 14in. Im looking for cheap tires mainly. Also, this saw has block guides. They are a little beat up. Should I replace them?
