Replace One Tire or a Pair?
2 Answers
Tire replacement can be done either as a single tire or a pair, depending on the situation: If the wear on the tire on the same axle side is not severe and still has a long service life, only the damaged tire needs to be replaced. However, if the tire on the same axle side is significantly worn and nearing the end of its service life, it is generally more reasonable to replace the pair. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are usually installed on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption capabilities.
Change one tire or a pair? As a car enthusiast, I always emphasize safety first. Changing just one tire may seem cost-effective on the surface, but if the tread depth difference between the new and old tires exceeds 2-3 millimeters, it can cause vehicle imbalance and affect handling, especially during sharp turns where grip becomes unstable, increasing the risk of skidding in rainy conditions. I learned this firsthand when modifying race cars, so I recommend replacing a pair to ensure symmetrical wear and avoid unnecessary suspension damage. Of course, you should consider the current condition of your tires—if they're only slightly worn and of the same model, replacing one might suffice. But in most cases, for driving stability and long-term maintenance costs, replacing a pair can save you from major repairs down the line. Regularly checking tire pressure and tread depth also helps prevent issues.
