How to Match Car Tires and Wheels?

Matching Method: Simply choose tires with the same size specifications as the vehicle's original factory tires for replacement. However, the following two points need to be noted: 1. Perform Tire Dynamic Balancing: Replacing tires will alter the mass balance between the tire and the wheel. An unbalanced wheel can cause severe vibrations during high-speed rotation, affecting driving safety. Therefore, after replacing tires, it is essential to perform tire dynamic balancing. 2. Consistent Specifications: When replacing tires, always ensure that the new tires have the same size specifications as the vehicle's original factory tires. Using tires that do not meet the required specifications can affect the vehicle's driving quality and even compromise driving safety, posing significant hazards.

How to Check for Refrigerant Leakage in a Car?

Methods for checking refrigerant leakage in a car: When the air conditioning is working normally, if bubbles continue to appear in the sight glass, it indicates a lack of refrigerant, which needs to be replenished; if there are no bubbles in the sight glass when the air conditioning stops, and no temporary bubbles appear, it indicates an excess of refrigerant, which needs to be discharged; if there are no bubbles in the sight glass when the air conditioning is working normally, but temporary bubbles appear when it stops, it indicates the refrigerant level is normal. Additional information: A method to determine if a car has a refrigerant leak is to place a regular thermometer 10cm away from the air outlet and inlet of the air conditioning unit, measuring the temperature at both locations. If the temperature difference is greater than 7°C, it indicates the air conditioning is functioning normally; otherwise, there may be a refrigerant leak.

What Causes Severe Engine Vibration?

Here are detailed explanations for the causes of severe engine vibration in cars: 1. Tightened Belt: In winter, belts become tighter than usual. When the belt tension is insufficient, the engine may produce sharp noises. 2. Dirty Throttle Body: Severe engine vibration, sometimes accompanied by failure to start at the first attempt, is often caused by a dirty throttle body or excessive carbon deposits in the fuel injector and intake passages. In cold conditions, carbon deposits can absorb some of the fuel, preventing it from fully entering the combustion chamber, leading to unstable idling and difficulty starting. 3. Check for Missing Balance Weights: Inspect whether the balance weights on the wheel rims are missing or if there is any noticeable deformation in the wheel hubs.
