Considering the possible weakness of the raw material end, it is expected that the inventory of production enterprises will decrease and the inventory of trading enterprises will increase [8]. - This week, the production schedules of domestic tire enterprises have mostly returned to normal levels, driving the overall capacity utilization rate to rise slightly. The production schedules of semi - steel tire enterprises have mostly remained stable. With concentrated orders for snow tires and a large number of specifications and models, the production enthusiasm of enterprises is expected to remain high.
