When comparing prices, focus on the maximum pressure (PSI/Bar) and clamping range. A professional-grade hydraulic bead breaker should typically handle 10,000 PSI to effectively break beads on OTR (Off-The-Road), tractor, or truck tires. Ensure the unit is made of high-grade forged steel rather than cast iron to prevent structural failure under high tension. Prices for pneumatic-hydraulic models are generally higher than manual ones but offer significantly better operational efficiency and safety for high-volume workshops.
