Equipped with double ball bearing so the wheel will roll very easily. The TPU tread has little cushion make it very resistant to wear and tear but will produce noise especially rolling on uneven surface.
We ordered these wheel exclusively as replacement for Thailand's JUMBO and SUMO Hand trucks. The tread is Brown ThermoPlastic Rubber, so they are guaranteed to roll smoothly and quietly. Compare to the default Black PU wheel, TPR wheel may last 2 times longer.
