NOV Rolligon manufactures Low Ground Pressure Tires for environmentally sensitive and hard to reach areas.  Rolligon Tires are primarily designed to provide Rolligon Vehicles or other similar vehicles with large surface area to distribute heavy loads when traveling over soft terrain that would not support the loads on conventional off-road tires.  The tires can also be used to introduce amphibious qualities to some vehicles and can be manufactured to match many axle designs.  They have a low ground compaction that allows them the flexibility to conform to the surrounding terrain causing minimal or no damage to the surface.  The low Ground Pressure Tires are made with Vidar protected rubber for maximum protection from penetration.
