It depends on the specific situation: If the tire shows signs of aging, it needs to be replaced immediately, regardless of how long it has been used or the extent of wear. Below are the details: Indicator marks: If the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters (there are indicator marks inside the longitudinal straight grooves of the tire tread indicating this depth), the tire must be replaced because its drainage capacity has significantly decreased, making driving on wet surfaces more dangerous. Damaged tires: Damaged tires should also be carefully evaluated for replacement. For example, a tire that has been run underinflated may still be drivable when inflated, but since the internal structure may have been compromised, it is recommended to replace it with a new tire promptly.

Does the owner need to go in person to replace the vehicle license plate?

Replacing the license plate does not require the owner to go in person. Relevant details are as follows: 1. Proxy: If you need someone else to handle it on your behalf, the owner must issue a "Power of Attorney," signed by both parties, and provide the original and a copy of the proxy's ID card. Additionally, before replacing the license plate, all traffic violation records must be cleared. 2. How to prevent license plate theft or loss: Park the vehicle in a secure parking lot, such as a gated community or a parking lot with surveillance cameras; enhance the vehicle's alarm system; currently, there is a type of anti-theft nut on the market, which has a stainless steel outer cover that is very hard—unless using an electric drill, it is difficult to pry open, making it a great helper for preventing license plate theft.

Is it necessary to install welcome pedals for sedans?

Installing welcome pedals for sedans has both advantages and disadvantages. The details are as follows: 1. Advantages: The most obvious advantage of installing welcome pedals is the decorative effect on the car. Many welcome pedals are connected to circuits and light up when the door is opened, creating a welcoming atmosphere for passengers. Additionally, welcome pedals can prevent shoes from scratching the car's threshold and damaging the paint when getting in and out of the car. 2. Disadvantages: Welcome pedals are usually attached with strong adhesive, making them prone to falling off in cold or hot weather, requiring repeated reattachment. Moreover, because they are fixed with strong adhesive, if the owner wants to remove them, stubborn, hard-to-remove glue residue is often left behind.

Why is the dashboard light of the Santana not working?

The dashboard light of the Santana is not working due to damaged power supply wiring or a blown power supply fuse. Damaged power supply wiring: If the wiring supplying power to the dashboard is damaged, resulting in an open circuit or short circuit, it can cause the car dashboard light to stop working. Blown power supply fuse: A fuse, also known as a circuit breaker, is an electrical component installed in a circuit to ensure safe operation. When there is a fault or abnormality in the circuit, the fuse will automatically blow and cut off the current when the current rises abnormally to a certain level. If the power supply fuse for the car dashboard is blown, it naturally results in no power supply, and the dashboard light will not illuminate.
