Tire technology requirements

Dynamic properties of rubber materials with respect to tire technology requirements. 

Revolutionary tire designs for high-tech passenger car radial (PCR) tires drives the developmental pace of the tire equipment manufactures. Triple-tread, asymetrical tread, or highly loaded silica compounds have a consequential impact on the extrasion machinery. In this context the design of the extmsion head and the extmders itself requires adaption to the new, challenging tire technology of today. 

In order to support and meet this demand an all-around development has taken place on the material front. Increasing automobile manufacmrers requirements and ever-growing customer expectations have resulted in the evolution of new product technology. As a consequence, mn-flat tire, closed cellular polyurethane (PU) tire, tweel tire, and active wheel system have become a reality on the road today and indicate a big change in the years to come. The manufacturing technology... 

The two forms of rubberized asphalt that have been tested the longest, asphalt-rubber and PlusRide , are patented. The required royalty fees increase the cost of these products. Although, initially, patents may have stimulated the growth of these products, they now appear to represent an economic barrier to increased scrap tire usage by these technologies. The patent for asphalt-rubber expires in 1991. After that more companies are expected to become involved, resulting in lower costs. Non-patented rubberized asphalt roadways are also being tested.
