Do tires need to be replaced in pairs?
2 Answers
It is recommended to replace two tires together. Replacing both tires on the same axle ensures identical tread patterns, which helps maintain smooth vehicle operation. When mechanics replace both tires, they also perform dynamic balancing to ensure even force distribution among all four tires. Relevant information about wheel alignment is as follows: 1. Introduction: Wheel alignment adjusts the four wheels' parameters to ensure optimal driving performance and reliability. 2. Function: Proper wheel alignment helps maintain stable straight-line driving, facilitates easier steering, and reduces wear on tires and steering components during operation.
Throughout my driving career, I've always prioritized safety when dealing with tire issues. It's generally recommended to replace both tires on the same axle simultaneously, such as changing a pair of front or rear tires together, because uneven tread depth between left and right tires can cause vehicle pulling or skidding. This risk is particularly greater during rainy conditions or high-speed driving. I personally experienced this once—after replacing just one front tire, I nearly lost control when turning on a wet road. Since then, I've strictly adhered to this practice. Additionally, checking tread depth is crucial. If the old tire has more than 3mm tread remaining, temporarily replacing only the damaged tire and placing it on the rear axle might be acceptable, but prolonged use in this manner will accelerate wear on other components and increase maintenance costs. Regular tire rotation also extends overall tire life—I perform this every 6,000 kilometers to ensure even wear.
