Is it better to replace two tires or all four?

It is better to replace all four tires. The maintenance methods for tires are: 1. Regularly clean the stones in the tire treads; 2. Reduce exposure to sunlight; 3. Frequently check the tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect the front wheel alignment; 6. Be mindful of driving habits. The functions of tires are: 1. Support the entire weight of the vehicle and bear the load of the car; 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components; 4. Adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring safety, handling stability, comfort, and energy efficiency.
When I only replaced two new tires before, I felt the car was not very stable when turning on slippery roads, because the tread wear on the old tires was too severe, and the uneven grip could easily affect braking performance. Experts recommend that the tread depth difference between new and old tires should not exceed 3 millimeters; otherwise, it may lead to handling issues or even skidding at high speeds or in rainy conditions. It's best to replace all four tires to ensure even wear and safety. If the budget is tight, you can replace them in pairs—front and rear—placing the new tires on the drive wheels. Remember to check tire wear every 5,000 kilometers, especially during harsh winter weather. Regular maintenance can also extend the vehicle's lifespan, saving money and hassle.
