Off-line inspection

After the production of tires, a series of tests such as appearance detection, uniformity detection, dynamic balance detection, X-RAY detection are required. Some manufacturers with detailed 

inspections will also have special internal bubble detection. After these tests, the tires can become qualified products off the line.

Tire performance sampling

In order to verify the performance of the tire, the tire manufacturer will carry out the rolling resistance detection, section size analysis, tire strength detection (puncture test), stripping strength, 

high speed, durability and other items of the batch of tires to verify the performance of the same batch of products.

Tire performance road test and product consistency certification

After the tire enters the automobile manufacturer as a supporting part, the automobile manufacturer will carry out a series of objective and subjective evaluation of the tire. Objective evaluation 

includes: dry ground braking, wetland braking, wetland linear drainage, wetland circumference, wetland planning, noise, rolling resistance, high speed, durability and other projects; Subjective 

evaluation includes: dry land control, wetland control, subjective comfort and other related evaluation; For Oems, winter tests on ice and snow roads are also carried out for all season tires.

Tire test

However, the above evaluation results can only show that the tires involved in the test are qualified, does not mean that all tires are qualified, so tire manufacturers to obtain sales qualifications 

also need to pass a series of certifications to ensure the consistency of the performance of tire products produced by their factories. So a large number of enterprises are proud of the certification 

mark.
