Tires are comprised of six major components (tread, belt, sidewalls, body plies, beads, and innerliner) and as many as 50 raw materials. Process control within the tire manufacturing plant is critical for ensuring high quality and consistent products on the final conveyor. 

Whether you are evaluating your internal processes, benchmarking best practices between plants, or potentially evaluating a potential tire supplier's plant, Smithers has the expertise to provide objective, third party audits of the manufacturing facility. Our team will work with you to build an audit plan based on specific areas of concern or development. The most common processes that we evaluate include:
  • Technology due diligence
  • Raw material inspection and qualification
  • Mixing
  • Extrusion
  • Calendaring
  • Stock preparations
  • Tire building
  • Curing
  • Tire inspection and repair
  • Tire Testing
  • On-site laboratory 
After the audit, our consultants will provide a detailed report detailing areas for improvement and baseline metrics that could be used for quality verification going forward.
