A track system for use as a replacement of a steerable wheel on a normally wheeled vehicle, is configured to improve the handling of the vehicle when operated over hard surface (e.g. packed dirt, pavement, concrete, etc.). The track system generally comprises a drive wheel configured to be mounted to the vehicle, a support frame mounted to the drive wheel or to the vehicle, front and rear idler wheels respectively pivotally mounted at the front and at the rear of the support frame, road wheels pivotal mounted along the length of the support frame, and a traction band disposed about the wheels and configured to be driven by the drive wheel. The road wheels are particularly configured to improve the handling of the vehicle when the track systems are operated over hard surface.
