What Does a Circle of Small Cracks on the Tire Sidewall Indicate?

Tire sidewall with a circle of small cracks indicates that the tire is aging and needs replacement. This has worn down to the tire's triangular limit mark, and the tire exhibits bulging, tread deformation, bead damage, sidewall crushing damage, or chemical corrosion. Tires with these issues all require replacement. Below is relevant information about tires: 1. Pay attention to the tire's shelf life: The sidewall of the tire will have a four-digit number indicating the manufacturing date, with the first two digits representing the week and the last two the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage. 2. Monitor the sidewall closely: As the tire rubber gradually ages, deep cracks will appear on the sidewall. However, as long as the sidewall has not been impacted and the cords are not broken, the tire can continue to be used. The triangular mark on the tire sidewall can help the owner locate a protrusion in the tread groove to determine the actual wear limit of the tire, which should be greater than 1.6 millimeters.

How to Bleed Oil Brakes?

The steps for bleeding oil brakes: 1. Remove the entire disc brake pump, with the upper and lower pumps and the oil pipe connected together; 2. When the exhaust port is tightly sealed, raise the lower pump and lower the upper pump; 3. When the upper pump is lowered, it should still be placed in the same direction as when installed on the vehicle (do not reverse it), then continuously press the brake; 4. After approximately every fifty to sixty presses, loosen the exhaust port (note: when the brake is released, loosen the exhaust port, then slowly press and release the brake lever. Press it all the way down and do not release it (if released, air may be sucked back into the oil pipe). Wait until the exhaust port is fully tightened before releasing. At this point, you will generally see oil and bubbles coming out of the exhaust port; 5. If the effect is not good or if the air is not completely removed, repeat steps 2-6.

Is it normal to have water mist inside the headlights after washing the car?

It is normal to have water mist inside the headlights after washing the car. The mist in the headlights is caused by the structure of the headlights and air flow, which is practically unavoidable. It tends to recur during seasons with significant temperature differences, such as winter or rainy seasons. The best way to deal with water mist in the headlights is to turn them on. Here is some extended information about car headlights: 1. Function: The main function of car headlights is to provide illumination for nighttime driving. Car headlights are also known as front headlights or LED daytime running lights. As the 'eyes' of the car, they not only affect the owner's external image but are also closely related to safe driving at night or in bad weather conditions. 2. Types: (1) By purpose: Car lights can be divided into two categories: lighting and auxiliary. Among them, only the front headlights and some fog lights equipped on certain cars serve the purpose of illumination, while the rest are auxiliary lights. (2) By type: Currently, there are four types of car headlights: laser headlights, LED car headlights, xenon headlights, and halogen lights.

Is it normal for a car to drive 1,500 kilometers a year?

Generally, the normal annual mileage is 20,000 to 30,000 kilometers. Precautions for driving: Stalling on complex road sections: This is often caused by improper coordination between the brake pedal and the clutch pedal. Stalling when following a vehicle uphill: This is a common situation for new drivers. Always pull the handbrake in time to prevent the car from rolling back. When starting, give more throttle to avoid stalling again. Keeping the left foot on the clutch pedal: When emergency braking is required at high speed, pressing both the brake pedal and the clutch pedal simultaneously will cause the vehicle to lose the engine's resistance, preventing it from stopping within the effective braking range and potentially leading to avoidable accidents. New regulations on the scrapping period for family cars: The 2021 new regulations on the scrapping period for family cars, as officially issued by the Ministry of Commerce in the "Mandatory Scrapping Standards for Motor Vehicles," remove the driving age limit for non-operational cars and set the scrapping mileage limit for private cars at 600,000 kilometers.

Why does the tire pressure warning keep coming on when there's no nail puncture?

Tire pressure is normal without any nail punctures, but the abnormal tire pressure warning indicates there might be a slight fault in the transmission circuit of the tire pressure monitoring system. It is recommended to have it checked. Generally, the normal tire pressure for passenger cars is around 2.2-2.5 bar, which is a standard. However, not all vehicle models follow this standard. For example, SUV models usually have slightly higher tire pressure than passenger cars, so the specific standard should be based on the manufacturer's guidelines. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. In winter, the tire pressure should be adjusted slightly higher by about 0.2 bar based on the standard tire pressure for car tires. Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can usually be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures.

How Long Can a Battery Last After Disconnecting the Negative Terminal?

After disconnecting the negative terminal, a battery can last for 1 to 2 months. Disconnecting the negative terminal only cuts off the standby power consumption of other components in the vehicle, but the battery still undergoes natural discharge, albeit at a slower rate. If left disconnected for too long, the battery may become depleted. The battery is a crucial component in a car, responsible for powering all electronic devices when the engine is not running. Also known as a storage battery, it operates by converting chemical energy into electrical energy. The commonly referred-to car battery is typically a lead-acid battery. Car batteries are categorized into conventional batteries, dry-charged batteries, and maintenance-free batteries. The normal service life of a car battery ranges from 1 to 8 years, largely depending on the vehicle's usage conditions.
