Do I Need to Replace All Four Tires?
2 Answers
Tires do not necessarily need to be replaced all four at once, but if conditions permit, replacing all four together can help maintain the original handling balance. Tires should be rotated every 5,000 to 8,000 kilometers. The functions of tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impact forces during driving, preventing severe vibrations from damaging vehicle components. Tire maintenance methods include: 1. Regularly clean stones stuck in tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect front wheel alignment; 6. Adopt careful driving habits—choose smooth road surfaces and avoid objects that may puncture or scratch tires, as well as chemical spills that could corrode tires.
From a safety perspective on tire replacement. Having driven for many years, I believe it's best to replace all four tires at once if possible, especially when there is a significant difference in wear between the front and rear tires. Not replacing all tires may lead to unstable vehicle handling, such as increased risk of skidding during emergency braking or on slippery roads. This concerns personal safety and should not be taken lightly. Additionally, many vehicle models, especially those with full-time four-wheel-drive systems, require all tires to be of the same size and wear level. Otherwise, the drivetrain may be subjected to excessive stress, shortening its overall lifespan. During each tire inspection, measure the tread depth to ensure it meets the standard (generally, replacement is needed if it's below 1.6mm), and rotate the tires regularly to reduce uneven wear. In short, safety comes first, and replacing all four tires is more worry-free. Of course, if the budget is tight, you can do it step by step, but at your own risk. It's advisable to visit a professional shop to assess the specific situation before making a decision.
