Just by looking at this off-road wheel, one can tell why it is called the HARTES METAL™ Rhino as it embodies the toughness of a rhino. During the design process, we took into consideration what would make this wheel stand out and we ended up conceiving an off-road wheel with a deep concave. It could even be stated that the deep concave on the Rhino resembles the horn of its animal counterpart.
