For everyone in comments they cut the tires because there are steel belts in them and shredding a whole tire would jam a shredder pretty fast so that why they cut them.This is a lot slower, and seems riskier to humans operating the equipment, then simply shredding the tires. How is the end product here better than what you would get out of shredding which is way more productive?That one that rips the steel out of the beed seems lazy by comparison.
