Should Car Tires Be Replaced in Pairs?

[McVictoria]

As long as the wear difference between the two tires is not significant, generally replacing a single tire is acceptable. If the old tire has been used for less than one year and the tread depth difference with the new tire is within 2mm, replacement in pairs is unnecessary. For old tires used between 1-3 years with a tread depth difference of 2-4mm, selective replacement can be considered. For old tires used over 3 years with a tread depth difference exceeding 4mm, it is recommended to replace them together. Below is relevant information about tires: 1. Under normal circumstances, the service life of a tire is approximately 70,000 kilometers. Theoretically, the tread wear on both sides of the car should be consistent during driving. If only one side is replaced, it may result in uneven tread wear between the left and right tires. 2. The main functions of tire treads are to enhance grip, reduce noise, and improve water drainage. If the treads on both sides are uneven, the performance of the tires may deviate, potentially causing the old tire to skid or lose traction during poor road conditions or emergency braking. 3. The height difference in tires can affect the outer circumference of the wheels. If the left and right tires are inconsistent, it may cause the car to pull to one side due to the old tire.
