What is the difference between tires with and without the three guarantees?

[AlessandraAnn]

The only difference lies in whether the "three guarantees" service (repair, replacement, and refund) is provided. Tires with the three guarantees refer to those that offer after-sales services for quality issues, while tires without the three guarantees do not provide any quality assurance after sale, and the manufacturer will not offer any compensation for any issues that arise. The three guarantees standards for tires are as follows: 1. If quality issues are found before actual use after purchase, the user can exchange for a new tire. For appearance-related quality issues, both parties can negotiate a solution. 2. If quality issues are discovered during use, the compensation standard is calculated based on the remaining tread depth, with specific regulations as follows: a. If the remaining tread depth is over 70%, a new tire will be provided free of charge. b. If the remaining tread depth is between 60% and 69%, the user can exchange for a new tire at 30% of the factory price. c. If the remaining tread depth is between 50% and 59%, the user can exchange for a new tire at 40% of the factory price. d. If the remaining tread depth is between 40% and 49%, the user can exchange for a new tire at 50% of the factory price.
