While systems such as those made by Mattracks allow users to replace their vehicle's wheels with tracks, AD Boivin Inc's Track N Go lets you simply add tracks onto your wheels when needed.

 

Each Track N Go kit includes four tracks and two loading ramps. To get the tracks onto your wheels, you start by placing the tracks on the ground two at a time (side by side) with the ramps leading up to them. You then just drive up onto them, and clamp them on – integrated rubber rollers press into the tire from either side, apparently holding everything securely in place.

 

One unmodified 4-wheel-drive vehicle can reportedly be set up with a complete set of tracks in under 15 minutes.
