A multiple layer foam insert replacement for a pneumatic inner tube for a tire. The multiple layer foam insert emulates the effect of air pressure, across a range of pressures, while still approaching the weight of the air filled tube. Through the use of different density materials and the orientation and thickness of such materials, the desirable characteristics of the pneumatic tube structure and performance can be emulated to a high degree. This multiple layer foam insert can be produced in varying levels of quality and function through the method of extrusion of foam materials in different sizes and layering.
