Retread tire production defects are serious issues that occur during the retreading process. Regardless of how advanced the technology is, the production method is sensitive to many factors involving exposure of the buffed surface to oxygen, humidity, temperature, and pressure, which all play a vital role in tire retreading techniques.

In this process, worn-out tires are selected and inspected before receiving new treads or casings. This method is both cost-effective and environmentally friendly. Retreading a tire involves applying new tire tread to the existing tire body, similar to manufacturing new tires. The use of quality tools can minimize production defects in retread tires. It is also necessary to understand the root causes of any problems resulting from the production process in order to identify and explore potential causes.
