The survey found that the market on the top of the enterprise, not only the quality assurance period is different, a lot of tire quality and claim period is from the date of production, the shortest three years, the longest 5 years. In other words, if the inventory time is short, the consumer enjoys a long period of quality assurance; conversely, if the tire stock time is long, the warranty period that consumers can enjoy will be shortened accordingly. When a tire that has been stored for more than two years is bought by consumers, consumers can hardly enjoy various claims rights during the warranty period.
