I like it over traditional tire bars, especially when disassembling and deflating numerous tractor trailer tires. The sturdy handle easily fits the valve stems and is heavy enough to hold the locking head in place. Inflating class 8 truck tires will definitely relieve some of the fatigue, you can endure those long periods of time. wait for tire pressure to reach 100+ psi. Saves your knees, back and hips from kneeling to hold the cartridge on the valve stems.
