Mold-On Rubber Wheels
Mold-on rubber wheels have a vulcanized rubber tread molded to a heavy duty cast iron core, and they offer a shock absorbing, semi-cushioned ride. These wheels easily roll over small debris, rough floors, cracks, floor joints, etc. The cushioned wheels provide a quiet rolling operation.
These wheels work well in outdoor environments, but the cast iron core can rust. If this is an issue, look at using aluminum or plastic core wheels. While they won't harm your floor, the black rubber may leave black marks. Other wheel options are available to prevent this.
