Can I Replace Just One Rear Tire?
2 Answers
It depends on the wear condition of the other rear tire. If the opposite tire is well-maintained, you can replace just one tire. Precautions for changing car tires: 1. Choose the appropriate tire: The specifications must match the original tire and be identical to the other tire on the same axle. 2. Valve stem: The valve stem should also be replaced when changing tires. 3. Pay attention to installation position: New tires should be installed on the rear axle. 5. Avoid sudden braking after installing new tires: Since new tires have deeper tread patterns and more tread hairs, and haven't fully broken in with the road surface, sudden braking may affect the vehicle's braking performance.
I once consulted a seasoned mechanic when changing tires. Replacing a single rear tire actually depends on the situation. If your tire has only been used for a few thousand kilometers with minimal tread wear, replacing just one with the same brand and model is generally fine. However, if it has run over 20,000 kilometers and the other three tires are nearly worn out, replacing only one new tire can cause a severe imbalance in grip between the left and right wheels. I experienced this once during heavy rain—the car's rear noticeably fishtailed when braking, which was terrifying. Now, I make it a habit to regularly check tire tread depth by inserting a one-yuan coin into the tread. If the top of the national emblem becomes visible, it's time to prepare for a replacement.
