How to Determine When Car Tires Need Replacement?

There are three main aspects to observe when determining if car tires need replacement. Below is an introduction to tire replacement: 1. Tread wear approaching the wear indicator. Generally, the wear indicator height for passenger car tires is 1.6 millimeters (this is also the legally mandated minimum tread groove depth), while for truck tires it is 2.4 millimeters. 2. Tire damage such as cracks or bulges. Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and multiple punctures by foreign objects. Especially with bulges, there is a risk of sudden tire failure at any time. As soon as any of these damages are noticed, owners should promptly visit a professional tire shop to inspect their vehicle's tires and replace them if necessary. 3. Tire age expiration. The typical lifespan of a tire is around 5 years. Beyond this period, tires begin to age. The primary signs of tire aging are surface hardening followed by the appearance of cracks.

Can You Still Drive with Damaged Spark Plugs?

You can continue driving for a short period with damaged spark plugs, but they should be replaced promptly. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. The condition of the spark plugs can be judged based on the following appearance colors. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is covered with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs like blistering at the top, black streaks, cracking, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected, the air-fuel mixture is too rich, or there is oil leakage.

When to Use the S Gear in the Avancier?

S gear is the sports mode - overdrive gear, suitable for speeding or when driving at high speeds. In this mode, the engine speed can rise rapidly and provide sufficient power for the car to accelerate instantly, making it a beneficial assistant when overtaking. Below is relevant information about the car's S gear: 1. The S gear in a car is the sports mode, where S stands for SPORT, commonly referred to as sports mode. Many performance cars are equipped with an S gear. In the S gear sports mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high speeds for a certain period to output greater torque, thereby increasing the car's power. 2. In the S gear sports mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high speeds for a longer time, allowing the car to move at high speeds in lower gears for an extended period, thus achieving greater torque output and acceleration. While the car is moving, simply push the gear lever into the "S" gear position. It is typically used for climbing slopes and quickly overtaking other vehicles.

What Causes Severe Vibration When the Air Conditioner is Turned On?

Severe vibration when the air conditioner is turned on may be caused by three main reasons. Below is an introduction to the possible causes of air conditioner vibration: 1. Faulty Air Conditioner Acceleration Device: Normally, when the air conditioner is turned on, the idle speed should increase by 200-300 RPM. If this acceleration device is damaged, severe vibration occurs. The acceleration device is essentially the idle speed solenoid valve, which may also become stuck and can be resolved by cleaning. 2. Throttle Body Carbon Buildup: Carbon buildup in the throttle body can cause the engine to struggle or barely manage to drive the compressor, leading to idle vibration. The throttle body needs to be cleaned. If the driving environment is harsh, it's best to clean it regularly, recommended every 10,000 kilometers. 3. Engine Mount Collapse or Damage: The engine's balance is disrupted, and turning on the compressor may reach a resonance frequency, intensifying the vibration.

Do I have to replace the tire if it gets punctured by a nail?

Generally, you don't need to replace the tire if it gets punctured by a nail. It can be repaired directly without major issues. Normally, a tire can be patched 3-5 times without problems, but it shouldn't be punctured in the same spot repeatedly, as this could create a large area of damage and pose a risk. If the tire tread is worn flat or the damage is severe, a new tire should be replaced. Below is an introduction to the functions of tires: Tires are one of the most important components of a car. Their main functions include: supporting the entire weight of the vehicle and bearing the load of the car; transmitting traction and braking torque to ensure the adhesion between the wheels and the road; reducing and absorbing vibrations and impacts during driving to prevent severe vibrations and early damage to car components; adapting to the high-speed performance of the vehicle and reducing driving noise; ensuring driving safety, handling stability, comfort, and fuel efficiency.
