Automatically Manufactured Tires by Liquid Injection Molding Test Results of Passenger Car Tires 810133

A new method of manufacturing pneumatic tires has been developed which shows considerable advantages over present bias and radial ply tires.
The LIM(R) process of tire production by liquid injection molding of polyurethane raw materials into a closed mold has shown favourable results both technically and commercially.
Development work has been progressing in four different areas - passenger car, truck, farm service, and off-the-road tires, but this paper will concentrate on test results generated on the passenger car tire programme. Wherever possible, control tires of either bias or radial ply type have been used for comparison purposes.
