Should You Replace All Four Tires at Once or Just Two?

Tires should be replaced all four at once because they bear the entire weight of the vehicle and require high balance. If not replaced simultaneously, it can affect the operational balance of the car. Tires are circular elastic rubber products mounted on metal rims, designed to support the vehicle body, absorb external shocks, maintain contact with the road, and ensure driving performance. The steps for replacing tires are: 1. Park the car, turn off the engine, and engage the handbrake; 2. Place heavy objects in front of and behind the wheels to prevent sliding, and set up a triangular warning sign behind the vehicle; 3. Use a wrench to loosen the lug nuts of the tire to be replaced in a diagonal pattern; 4. Position the jack on the side of the tire to be replaced and lift the vehicle to a certain height; 5. Remove the lug nuts and take off the old tire; 6. Install the spare or new tire and tighten the lug nuts diagonally; 7. Lower the vehicle by releasing the jack and ensure all nuts are securely tightened.
