Why does tire pressure drop in cold weather?

As the temperature drops in cold weather, the air inside the tires is affected by the temperature, leading to a decrease in tire pressure. In cold weather, the tire pressure of car tires should be appropriately increased. Based on the standard tire pressure of the car tires, it is recommended to increase the pressure by about 0.2 bar. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and tendencies to veer, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in tire blowouts; Increases tire body deformation, making the tire side prone to cracks, and generates flexing movements, leading to excessive heat, promoting rubber aging, cord fatigue, and breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.

Which One to Choose: Michelin Primacy 4 or Energy XM2+?

Primacy 4 is relatively better, except for being slightly inferior to Energy XM2+ in terms of wear resistance. Below are the detailed introductions of the two tires: 1. Primacy 4: Michelin Primacy 4 not only maintains the consistent quiet and comfortable attributes of the Primacy series but also delivers excellent wet grip performance, whether new or worn. It uses a high-performance rubber compound to ensure outstanding wet grip performance even when the tire is worn. The short braking distance makes driving safer, which is a major highlight of Michelin Primacy 4, even surpassing its quiet and comfortable nature. 2. Energy XM2+: Michelin Energy XM2+ performs very well in terms of braking distance, impact resistance, and mileage, but its tire noise is exceptionally noticeable, which has drawn complaints from many car owners.

Can You Drive the Day After Drinking?

It mainly depends on the specific time of drinking. You need to wait more than 24 hours before you can drive a motor vehicle, as alcohol metabolism takes a certain amount of time. You must meet this time requirement before driving a motor vehicle; otherwise, it is considered illegal. Below is relevant information about drunk driving: 1. Hazards: Driving a motor vehicle after drinking alcohol reduces your ability to control the vehicle, impairs judgment of road conditions, slows reaction time, affects vision, and leads to unstable driving mentality, making fatigue very likely. 2. Penalties: Driving under the influence of alcohol results in 12 penalty points, a six-month suspension of the motor vehicle driving license, and a fine.

What Causes Steering Wheel Noise in Cars?

Causes of steering wheel noise in cars: 1. Friction between plastic components: The steering wheel consists of various plastic parts, and if the gaps are too small, abnormal noises may occur; 2. Interference from the airbag spring: If the sound comes from inside the steering wheel, remove the steering wheel and apply some grease to the airbag clock spring. If the noise persists, the airbag clock spring needs to be replaced; 3. Noise from the shock absorber plane bearing: Open the hood and listen to see if the sound is coming from the top of the shock absorber. If it's the shock absorber plane bearing making noise, apply some grease to it. If the noise continues after greasing, the bearing needs to be replaced; 4. Improper tension or aging of the power steering belt: For mechanical and hydraulic power steering systems, if the belt is not properly tensioned or has aged, abnormal noises will be heard. Adjust the belt tension or replace the belt as needed.

How to Turn on the High Beam and Low Beam Lights in Volkswagen?

Method to turn on the high beam and low beam lights in Volkswagen: There is a set of light combination switches on the left side of the steering wheel. Rotating the combination switch forward one notch turns on the dashboard lights, rotating it another notch turns on the low beam lights, and rotating it one more notch turns on the high beam lights. The high and low beam lights are used for illumination during night driving. Volkswagen is an automobile manufacturing company headquartered in Wolfsburg, Germany, with models such as Touareg, Tiguan, Tiguan L, and Teramont. For example, the Sagitar is a joint venture sedan brand under Volkswagen, positioned as a German high-performance sedan, with body dimensions of 4753mm in length, 1800mm in width, and 1462mm in height, and a wheelbase of 2731mm.

How many kilometers should the spark plugs be replaced for the Sagitar 1.4T?

The spark plugs for the Sagitar 1.4T should be replaced every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage wires in the correct firing order and secure the cover.

Can the car be turned off after driving through water without stalling?

If the car did not stall while driving through water, it can be turned off after coming out of the water. Here are some precautions for driving through water: 1. Drive in a low gear: Use a low gear (for automatic transmission vehicles, shift into hill-climbing mode) and drive slowly and steadily through the waterlogged area while maintaining control of the steering. Be aware of any potholes or hidden obstacles beneath the water. 2. Do not restart the engine if it stalls: If the vehicle stalls in a waterlogged area, do not attempt to restart the engine. Stalling indicates that water has entered the cylinders. Restarting the engine can cause severe damage due to the incompressibility of water, potentially bending or breaking the piston connecting rod components, and in extreme cases, leading to complete engine failure.
