Summer tire pressure of 3.0 is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. 3.0bar is higher than the maximum value of the standard tire pressure, so it is not normal. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting the braking effect; It will cause steering wheel vibration and deviation, reducing driving comfort; Accelerate the local wear of the tread pattern in the center of the tire, reducing the tire life; The vibration of the car body increases, which indirectly affects the life of other parts; It will cause excessive extension and deformation of the tire cord, reducing the elasticity of the tire body, and increasing the load on the car during driving; The puncture resistance performance decreases. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate the tire, and the impact will cause internal cracks and explosions, leading to a flat tire.

Where is the best place to install ETC in a car?

The ETC device is generally installed in the upper middle part of the front windshield for passenger cars, while for large vehicles like trucks and buses, the installation position is in the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is not made by the owner themselves, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); A photocopy of the organization code certificate or business license (with official seal); The original ID card of the agent; The original vehicle registration certificate; The vehicle that needs to have ETC installed. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which can reduce the driver's field of vision. If this is not considered when installing ETC, it may increase the driver's blind spot. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced, as it has a solar panel on the back for self-charging. Therefore, when installing, avoid the black areas on the windshield and positions that may easily block the solar panel. Do not remove it randomly once installed: The button in the middle of the adhesive is an anti-removal guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If the tag is removed randomly, the guide rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.

Is Full Car Wrapping Necessary?

Full car wrapping is necessary if you want to better protect the car's paint. Here are some introductions about car wrapping: 1. Precautions for car wrapping: When applying the wrap, it is essential to choose high-quality film and have it installed by a professional shop. Inferior wraps may not meet light transmittance standards, which can affect the driver's visibility during night driving. It is not recommended to apply film on the front windshield as it may obstruct the driver's view. When wrapping the front side windows, two sections should be cut out to ensure the driver has a clear view of the side mirrors. After the wrap is applied, avoid rolling the windows up and down immediately, as this can cause the film to peel off. 2. Duration of car wrapping: Generally, car wraps can last for about three years. After removing the wrap, a lot of adhesive residue may remain on the windows. Before attempting to remove this residue, it is important to soften the adhesive first to facilitate removal. If the adhesive is not softened and scraped off directly, it can leave many scratches on the glass. After softening the adhesive with alcohol or essential balm, use a plastic scraper to remove it, avoiding the use of hard metal tools.

How to Distinguish Between Good and Bad Car Window Tint?

High-quality tint film should allow clear visibility of objects beyond 6 meters at night, while inferior films often appear hazy. Genuine films feel thick and smooth to the touch, whereas poor-quality films are thin and brittle, prone to wrinkling. Here is more information about car window films: 1. Overview: Car window tinting (Auto-tint-film) involves applying a thin film layer to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also known as solar film or heat-insulating film. 2. Functions: It blocks UV rays, reduces heat, prevents injuries from shattered glass, and minimizes glare.
