Is it necessary to replace two tires at once?
2 Answers
Whether it is necessary to replace two tires at once depends on the specific situation: 1. If one of the four tires on a car is accidentally damaged and needs to be replaced, only that one tire needs to be changed; 2. When tires are worn down to the specified position due to normal wear and need replacement, it is recommended to replace two tires at the same time. Precautions for tire use include: 1. Pay attention to the degree of tread wear; 2. Avoid tire pressure being too high or too low; 3. Remove debris from the tread to prevent punctures that could lead to air leaks or blowouts; 4. Rotate tires regularly to prevent uneven wear. The functions of tires are: 1. To cushion the impact experienced during driving; 2. To ensure good comfort and smooth driving; 3. To maintain good adhesion between the wheels and the road surface, improving traction, braking, and off-road capability; 4. To bear the weight of the vehicle and ensure its driving performance.
Regarding your question about replacing two tires, I often help friends with such matters. Actually, it's not always necessary to replace them in pairs, but it depends on the specific situation. If only one tire on the same side is punctured and the other three tires are still quite new, having only run a few thousand kilometers, then you can just replace that one. The key is that the new tire must be of the same brand, tread pattern, and specifications as the old tire on the same axle, otherwise the vehicle may vibrate and the steering may become unstable at high speeds. However, if your car has already driven 20,000 to 30,000 kilometers and the wear on the old tires is quite noticeable, replacing just one tire can create uneven grip on both sides, making it prone to skidding when turning in the rain. I recommend that for cars with over 30,000 kilometers, it's best to replace two tires together for better balance and safety.
