What are the symptoms of a bad car wheel bearing?

The symptoms of a bad car wheel bearing include: 1. The wheel wobbles when the car is moving; 2. Unusual noises occur; 3. Poor rolling, leading to a decrease in power. Methods to diagnose a bad car wheel bearing: 1. Open the window and listen for sounds; 2. Increase the speed, shift to neutral, and let the vehicle coast to observe the noise; 3. Temporarily stop the car and check the temperature of the wheel hub; 4. Lift the car with a jack and manually rotate the four wheels quickly. Causes of a bad car wheel bearing: 1. Improper wheel installation; 2. Improper assembly or adjustment; 3. Poor lubrication; 4. Quality issues with the bearing itself.

How Often Should Car Filters Be Replaced?

Car filters should be replaced at the following intervals: 1. Oil filter: generally every 5,000 to 8,000 kilometers; 2. Fuel filter: generally every 10,000 to 20,000 kilometers; 3. Air filter: generally every 10,000 to 20,000 kilometers; 4. Cabin air filter: generally every 20,000 kilometers. There are four main filters in a car: the oil filter, fuel filter, air filter, and cabin air filter. Taking the oil filter as an example, it is installed in the oil passage. During circulation, the oil first passes through the filter to remove impurities before flowing to various lubrication points. This filtration process helps to better lubricate component surfaces and reduce friction. The lifespan of an oil filter depends on factors such as the material of the filter paper, filtration area, and strength. Higher-quality filter paper and a larger filtration area contribute to a longer lifespan. Typically, an oil filter lasts between 5,000 to 8,000 kilometers, but this should be determined based on the filter's quality, driving habits, vehicle wear conditions, and oil quality.

How to Identify the Maximum Speed Rating on Car Tires?

Car tires' maximum speed rating can be identified by looking at the letter following the numbers on the tire sidewall. Taking 195/65R1588H as an example: the letter H here represents the maximum speed rating. The speed rating of a tire is usually indicated by letters and numbers, showing the tire's maximum speed capacity under specified conditions while carrying the designated load. During driving, the vehicle speed must not exceed the tire's speed rating. This applies to all tires on the vehicle, including the spare tire, which should be inspected monthly. Methods for maintaining car tires: 1. Regularly check the tire surface for cracks or deformations; 2. Avoid sudden acceleration whenever possible; 3. Conduct periodic tire pressure checks.

What is the normal tire pressure for car tires?

Car tire pressure is normally between 2.3bar and 2.5bar. The hazards of low tire pressure: 1. Increased fuel consumption due to higher road friction coefficient; 2. Heavy steering wheel, prone to deviation, which is detrimental to driving safety; 3. Increased movement of various parts of the tire, causing abnormal heat due to excessive rolling; 4. Weakening of cord and rubber functions; 5. Damage to the tire bead area and abnormal wear. The hazards of high tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear of the tread pattern in the center of the tire; 4. Impact on the lifespan of other components; 5. Excessive stretching and deformation of tire cords; 6. Increased risk of tire blowout.

What is the normal tire pressure for car tires?

The normal tire pressure for car tires ranges between 230 to 250kpa. However, the specific recommended tire pressure should be based on the manufacturer's suggestion, which can usually be found in the vehicle's user manual, on the label near the driver's door (B-pillar), or on the fuel tank door. These sources will provide detailed information on the recommended tire pressure for your specific vehicle. Tire pressure is also significantly affected by seasonal factors. In summer, when temperatures are high, tires tend to heat up during driving. Higher tire pressure can increase the risk of a blowout, so it's advisable to keep the pressure slightly lower. In winter, tire pressure should be a bit higher than in summer due to the principle of thermal contraction and expansion. Generally, a tire pressure between 250 to 280kpa is more suitable for cars during winter.

What to Do When a Car Tire Gets Punctured by a Nail?

Solutions for a car tire punctured by a nail: 1. Pull over to the side of the road and turn on the hazard lights, then place a safety warning sign behind the car; 2. Inspect the tire to check if it is leaking air after being punctured. You can spray some soapy water on the punctured area to see if bubbles form. If bubbles appear, it indicates a leak; otherwise, there is no leak; 3. If there is no leak, drive slowly to a repair shop for further handling. If there is a leak, seek roadside assistance. Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain good traction between the wheels and the road, improving the car's traction, braking, and off-road performance.
