[VonBrooke]

4S car tire three-guarantee refers to warranty, replacement, and refund, with the following regulations: 1. After purchasing tires: If quality issues are found before actual use, new tires can be exchanged. For appearance quality issues, both parties can negotiate a solution. 2.

The specific regulations are as follows: (1) If the remaining tread depth is more than 70%: Free replacement of new tires. (2) If the remaining tread depth is 60%-69%: Replace new tires at 30% of the factory price. (3) If the remaining tread depth is 50%-59%: Replace new tires at 40% of the factory price. (4) If the remaining tread depth is 40%-49%: Replace new tires at 50% of the factory price. (5) If the remaining tread depth is 30%-39%: Replace new tires at 75% of the factory price.
