The radial tire replaced the simple bias tires (which made up 90% of the market only 5 years earlier) and within a few years virtually all cars were rolling on radials.

Owing to the complexity in bias tire structure and material properties, it is both economical and exact to model the tire by using layer elements and solid elements.

The LLB 1525 double bias tire press was transformed into the all steel radial tire press by modifying its mechanical parts, water and steam pipelines, electrical and heating control systems.
