Can I Replace Just One Car Tire?

If the tread wear on the car tire is still relatively shallow, it is acceptable to replace just one tire, 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 consistent tread patterns, structure, brand, and specifications. If the tire tread wear is severe—for example, if the tires have been driven tens of thousands of kilometers but do not yet require replacement, and only one tire has an issue—replacing just one tire can significantly impact driving safety. This may lead to vehicle drift or even loss of control. The reason is that when a tire is heavily worn, the new tire will have greater friction and grip compared to the old one. The old tire, with weaker grip, can cause the vehicle to drift or lose control due to the imbalance in traction. Additionally, the vehicle may experience uneven height, leading to bumpiness or drift issues at higher speeds. Therefore, in such cases, it is best to replace a pair of tires.
I once changed a tire by myself, but the car started shaking when driven. After taking it to the repair shop, I found out the problem was serious. The reason was simple: uneven tire wear, with a significant difference in tread depth between the new and old tires, causing imbalance and unstable steering. Over time, this can also accelerate suspension wear. The mechanic recommended replacing at least two tires on the same axle, such as both front or both rear tires, to ensure grip and safety. Additionally, when replacing tires, it's best to use the same brand and model to avoid performance differences. Regular tire rotation is also important—swap their positions every 8,000 kilometers to extend their lifespan. Remember, saving small money might lead to big repairs later, and safe driving is the top priority!
From a safety perspective, replacing just one tire carries significant risks. Uneven tire wear can affect the vehicle's dynamic balance, leading to issues like uneven grip during sharp turns and extended braking distances. This is especially dangerous in rainy conditions or at high speeds, where the risk of skidding increases. It's advisable to check the wear level of the existing tires. If the tread depth difference between the new and old tires exceeds 4mm, they must be replaced in pairs. For four-wheel-drive vehicles, extra caution is needed as mismatched sizes can damage the differential. Additionally, after replacing the tires, a four-wheel alignment should be performed to minimize abnormal wear. In short, when it comes to driving safety, no detail is too small. Don't cut corners by replacing just one tire; investing in a pair ensures greater peace of mind.
