Impact on Tire Performance with Improvement of Semisteel Meridian Tire Lamination Processing

The performances of tires which are affected by improving the building way for semisteel radial tire have been researched. The testing results show that there is a great effect on the tire’s uniformity and dynamic balance because the pressing ways of semi-steel radial tire bis two steps with two rollers lamination make the variation of tread size greater. When the lamination process of two steps with two rollers was changed into three steps with three rollers, the tire’s uniformity and the dynamic balance have been improved effectively, which significantly reduces the possibility of the change when the tread size becomes larger during the lamination of tread.
