SlimLites and Apollo Series. Robby Gordon Signature Wheels. Hoping to be used as a true all-terrain tire, we wanted to know what kind of terrain the Fun Country was designed for. While a lot of this had to do with the fact we only had two-wheel-drive, the sensation of not having the truck react too quickly in the sand is preferred as it allows you to have a more controlled drive across the terrain rather than having to provide constant steering inputs to correct. The tread pattern is certainly unique and it works really well in all conditions. In addition, three-ply sidewalls help with vehicle stability on the road and extra puncture resistance off-road. More Rocks and Carnage, Fewer Survivors.
