What are the effects of larger tire sizes?

Tire sizes that are too large will result in shorter mileage, failure to pass annual inspections, increased fuel consumption, and may lead to phenomena such as 'tire wear' or 'pulling to one side,' as well as reduced tire lifespan. Specific effects of larger tire sizes: Original tires are more in line with fuel consumption standards. Larger tires mean increased weight, leading to higher fuel consumption during driving. Mileage becomes shorter because as the tire and rim size increase, the tire's diameter and radius lengthen, increasing the circumference. This results in a reduced rotation speed and noticeable changes in the distance covered per rotation. Failure to pass annual inspections is due to Article 16, Section 1 of the 'Road Traffic Safety Law of the People's Republic of China,' which states that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Precautions for replacing car tires: When selecting tires, the specifications must match the previous tires and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing tires, the aging cycles of the new tire and valve stem differ. During the new tire's lifespan, the valve stem may develop issues that are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Installation direction and inflation: If using original equipment tires, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. For directional tires, align the arrow on the wheel with the car's forward direction. When inflating, fill to the maximum pressure allowed by the tire, then reduce to the manufacturer's specified standard pressure.

What lights to use when preparing to overtake?

When preparing to overtake, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not recommended to signal and overtake, as this can easily catch the following vehicle off guard. Additional information is as follows: 1. Overtaking lights: Whether during the day or at night, overtaking is done from the left side. Overtaking from the right is generally not allowed and is very dangerous. When overtaking, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not recommended to signal and overtake, as this can easily catch the following vehicle off guard. 2. Overtaking precautions: To prevent the vehicle ahead from changing lanes during overtaking, it is essential to alert them by honking or quickly switching between high and low beams. Observe the vehicle ahead; if there is no intention to change lanes, you can then accelerate to overtake.

What is the oil specification for the Golf 7?

The Volkswagen Golf 7 uses engine oil with a specification of 5W-40. Under normal circumstances, the oil change volume is less than 5 liters. It is essential to choose a high-quality oil brand product to avoid purchasing inferior oil, which could affect the engine. Below is relevant information about engine oil: 1. Engine oil has a significant impact on the normal performance and lifespan of the engine, so car owners should strictly follow the vehicle's user manual to select the same series, grade, and viscosity of oil. 2. The oil specified in the car manual is determined based on the engine's performance and the temperature of the sales region, providing certain guidance for oil selection. 3. If the owner does not use the oil specification stated in the manual, they may not be able to claim warranty for engine damage during the warranty period. During the oil addition process, the oil level should be kept between the upper and lower marks on the dipstick; otherwise, excessive oil can lead to carbon buildup.

How Many Kilometers Should a New Car Drive Before an Oil Change?

New cars require an oil change every six months or 5,000 kilometers. For mineral oil, it is generally recommended to change every six months or around 5,000 kilometers. If semi-synthetic oil is used, the interval extends to 7-8 months or approximately 7,500 kilometers. Full synthetic oil, on the other hand, can last for one year or about 10,000 kilometers before needing a change. Below is an introduction to these types of engine oils: 1. Mineral Oil: Mineral oil is the residual oil left after gasoline and heavy oil are refined from petroleum. While it is a natural oil, it contains more impurities compared to semi-synthetic and full synthetic oils. It is cheaper but offers poorer lubrication for the engine and has a shorter service life. 2. Semi-Synthetic Oil: Semi-synthetic oil falls between mineral oil and full synthetic oil. It contains a large number of anti-corrosion additives to enhance the oil's stability and oxidation resistance. 3. Full Synthetic Oil: Among the three types, full synthetic oil is the highest in quality and durability, and also the most expensive. Typically, it can be used in passenger cars for 10,000-12,000 kilometers without deteriorating.

Why do xenon headlights turn yellow?

Xenon headlights have a certain lifespan. As the usage time increases, the color temperature of xenon headlights drops below 5000K, making them noticeably yellow. Below is an introduction to xenon headlights: 1. Introduction: Xenon headlights refer to high-pressure gas discharge lamps. Xenon headlights are heavy metal lamps that fill an anti-ultraviolet crystal quartz glass tube with various chemical gases, such as inert gases like xenon. Then, a booster increases the vehicle's 12-volt power supply to 23,000 volts instantly. Under high voltage, xenon gas is ionized, producing a light source between the two poles of the power supply. Xenon headlights are known for their energy-saving properties and good color temperature. 2. Advantages: (1) Xenon bulbs have three times the luminous intensity of ordinary halogen bulbs while consuming only two-thirds of the energy. (2) Xenon bulbs use a light color nearly identical to daylight, creating better visual conditions for drivers. Xenon headlights provide a wider range of illumination and greater light intensity, significantly improving driving safety and comfort.

How to Open the BMW Sunroof?

When pressing the position of the sunroof switch, the automatic sunroof and rear sunshade will open safely. Pressing the switch again will fully open the sunroof. The advantages of the BMW panoramic sunroof are as follows: 1. Due to the large sunroof area, it can keep the air inside the car fresher and quickly remove odors compared to ordinary cars. 2. The ultimate enjoyment of looking up at the sky. For the BMW 5 Series, simply opening the sunroof and utilizing the negative pressure formed on the roof during driving can quickly extract hot air to achieve rapid ventilation and cooling. This method is 2-3 times faster than using the BMW 5 Series air conditioning for cooling and also saves gasoline. 3. When driving at high speeds, it can more effectively reduce interior noise compared to opening side windows. 4. It can quickly lower the interior temperature, making it an excellent way to dissipate heat for cars exposed to the sun.
