Is it necessary to replace tires in pairs?

Criteria for determining whether tires need to be replaced in pairs: When the wear on car tires is minimal: Replacing just one tire is sufficient, as the wear on tires on the same axle is generally similar. However, it is essential to ensure that the tires on the same axle have identical tread patterns, structure, brand, and specifications. When the wear on tires is severe: In this case, it is best to replace a pair of tires. If a car has driven tens of thousands of kilometers but the tires do not yet need replacement, and only one tire has an issue, replacing just one tire can significantly impact driving safety, potentially causing the vehicle to pull to one side or even lose control. This is because severely worn tires have less friction and grip compared to new tires. Replacing only one tire creates an imbalance in grip strength, leading to pulling or loss of control. Additionally, the vehicle may experience uneven height, resulting in bumpiness or pulling issues at higher speeds.
You don't necessarily have to replace tires in pairs, but based on my over ten years of driving experience, I generally recommend replacing them in pairs for better safety. Uneven tire wear can lead to unstable handling, especially at high speeds or in rainy conditions, where differences in grip between the left and right sides can cause the vehicle to skid. If you choose to replace just one tire, make sure the new tire matches the old one in model, size, and tread depth, with a difference no greater than 2/32 inches—otherwise, steering may feel loose. I also recommend regular tire rotation to distribute wear evenly and extend tire life. In case of an unexpected puncture, prioritize safety by replacing a pair rather than just one to avoid compromising driving stability over minor savings.
