The OTR tire is mainly used in various giant engineering vehicles in the mine, including excavators, scrapers, graders, large dump trucks, tippers and other engineering machinery. Their common feature is that they have heavy loads and poor service conditions. This puts forward higher quality requirements for the steel cord as its main framework material.
