Spiked wheels can be made for any kind of wheeled vehicle, from a carriage to a waggon. Rather than the normal band of metal around the rim of the wheel, a spiked wheel is studded with inch-long spikes every six inches around the entire circumference of the wheel. These spikes dramatically increase the traction of the wheel by gouging into whatever ground they pass over, allowing the vehicle to operate normally on ice or on a steep incline. However, this traction does slow travel slightly, reducing the speed of the vehicle by five feet per round.
