GOODYEAR ROLLIGON TIRES - A New Approach to Vehicular Mobility

The Goodyear Rolligon tire development program has partially explored a field of extremely low pressure tires and the application of these tires to vehicles as a means of extending vehicular mobility.

The tire characteristics explored have included:

• Low ground bearing pressures.
• Flexible tire surface and side wall.
• Deflection at operating loads and pressures.
• Low skin stresses in tire surface.

The program has also included the exploration of vehicle design concepts such as:

• Utilization of walking beam.
• Integral central inflation system.
• Axle and peripheral drive and loading.
• All wheel drive.

Field testing indicates that increased tired vehicle mobility has been achieved.
