Can I Replace Just One Tire on a 4WD Vehicle?

[EmmettRose]

You can replace just one tire on a 4WD vehicle. Tire Replacement Considerations: When the puncture on the tread is only 6mm, for economic reasons, you can simply patch the tire and continue using it without replacement. This is because a metal piece inserted into the tire won’t significantly damage its structure—only creating a hole through the steel wires, fabric layers, and polyester layers, which can be repaired. Of course, replacing the tire is safer, and the damaged tire can then be used as a spare. Tire Maintenance: Rotate the tires every 10,000 kilometers to ensure even wear and prolong tire life. Avoid rapid acceleration, hard braking, or sharp turns while driving. It is recommended to perform a wheel alignment every 2,000 kilometers to reduce abnormal tire wear caused by changes in the main wheel alignment parameters. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning ability. Additionally, tires need to exhibit high wear resistance and flexibility, along with low rolling resistance and heat generation.
