The wheel is very nice: attractive brown TPR tread on milk PP core. TPR wheel is cushion, easy rolling. SUPO uses high quality material to ensure the wheel is durable and wear resistant. You may want it to replace your suitcase wheel.
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.
