Quality Control System at GT Radial Plants

GT Radial has implemented a comprehensive quality control system at all seven of its tire plants. Strict quality control measures ensure that the quality of raw materials meet required specifications. GT Radial also conducts inspections at each stage of the production process to ensure that each component meets relevant specifications and standards.

GT Radial subjects tires to a final inspection before packaging them for delivery. With the use of an internal numbering system, the factories and distribution centers are able to monitor the employee group responsible for a particular production process, for each tire that is produced.

Part of the efforts to keep improving quality and safety standards include a single barcode located on the tire’s sidewall for backward tracing from the raw materials used all the way to the final product.

Operational Excellence and EHS (Environmental, Health and Safety)

GT Radial is fully committed to maintaining the highest standard of quality control procedures. And in 2018 the company has passed the IATF16949: 2016 certification which is the quality management system for the latest edition of the automotive industry and ISO14001: 2015 the latest edition of the environmental management system from TUV Nord Indonesia.

GT Radial Excellent System governs not only operational excellence and efficiency but also employee health and safety in the work place and environmental sustainability by reducing natural resources and increasing reuse/recycling.

GT Radial ETC (European Technical Center)

GT Radial has made a significant investment in a European tire testing facility, hosted at the internationally acclaimed MIRA Ltd Proving Ground (previously called Motor Industry Research Association) at Warwickshire, just outside of Birmingham, UK. ETC consists of highly experienced tire testing and development staffs to provide development and evaluation capacity to GT Radial's R&D Center in China.

Proving Grounds

If indoor testing is successful, tires will be incorporated in one or more of the four GT Radial Proving Grounds located in: China (Anhui and Taiwan), the United Kingdom, and Finland (for winter tires).

On the test tracks, skilled drivers put tires through the paces to measure:

  • • Handling and Stability at High Speeds
  • • Riding Comfort
  • • Wet Handling
  • • Braking and Cornering
  • • Noise Levels (both inside the vehicle and outside)
  • • And more

Then, and only then, is the tire ready for the market. When you purchase a brand produced by GT Radial, you can do so with confidence in the fact that it was born from one of the most strenuous R&D programs in the tire industry.

Environmental Friendly Tires

Environmental Friendly Tires

Today’s motorists are looking for safety, long tread life, fuel savings, and services that make traveling easier.

At GT Radial R&D – We challenge ourselves not only to deliver a balanced performance of tire safety and durability but also less fuel consumption and to meet the expectations of each customer.

Tire Usage Perspective

Tire Usage Perspective

More than 60% of the world’s oil output is used in transportation. In trucks/buses, tires contribute to approximately 30% of fuel consumption, or one full tank on every 3 trucks/buses, that can be saved by using the right tires with correct maintenance.

After years of research, GT Radial successfully developed tire production that consumes less fuel without sacrificing performance, and is verified by the US Environmental Protection agency, SmartWay.

In addition, GT Radial continually attempts to educate the public about the most fuel efficient ways to make use of a tire, how to select and maintain energy saving tires while providing the most professional solutions, and giving advice to fleets and users on how to reduce fuel consumption and cost. By providing the right tires and relevant technical support, GT Radial will help promote sustainable development of the industry while creating environmental benefits to the society.

Tire Manufacturing Perspective

Tire Manufacturing Perspective

Energy and non-renewable raw materials are becoming scarcer and more expensive. Optimizing their use and conserving them over the long term is essential. The challenge is to meet all of these goals without sacrificing tire performance, while being mindful of our responsibility to the environment and the people who live in it.

In this way, GT Radial is committed to reducing air emissions, water emissions, scrap and indirect materials, while increasing reuse/recycling.

Environmental Conservation Perspective

Environmental Conservation Perspective

GT Radial’s parent company has donated USD $1 million for 260,000 hectares of conservation projects in various areas, through a partnership agreement with Conservation International (CI).

Protecting these forest areas from conversion into vegetation with lower biomass (tree plantations or agriculture) conserves about 100 tons of carbon per hectare, or 26 million tons of carbon in total. This is equivalent to about 100 years of carbon emissions resulting from coal burning at GT Radial plants.
