How Long Can Tires with Small Cracks Still Be Used?

If the tires have been used for more than 3 years and only show some fine cracks on the tread, it indicates mild aging, and they can still be used temporarily for about a year. However, if the tires have been used for more than 5 years, they become harder, produce more noise, and essentially lose their rubber properties, making them unsafe for further use. In such cases, they should be replaced promptly. Below are some additional details: 1. Tire Aging: Another sign of tire aging is the peeling of tread patterns. Once peeling starts, the remaining tread will likely follow, significantly reducing the tire's grip. This can lead to skidding in rainy conditions, decreased acceleration performance, poor cornering grip, and noticeably longer braking distances. To ensure driving safety, such tires should be replaced immediately. 2. Precautions: If the cracks are deep enough to expose the internal fabric of the tire, it is clear that the tire is no longer suitable for high-speed driving. It is advisable to replace it, as continued use increases the risk of a blowout.

Won't the Tram's Overhead Wires Detach?

Tram's overhead wires won't detach. Below is the relevant introduction: 1. Principle: The tram maintains its route through the contact between its wheels and the tracks. Simultaneously, the pantograph (the visible current collector) on the tram's roof connects the tram to the overhead wire, forming a power-receiving circuit to ensure the tram can draw electricity. 2. Reason for non-detachment: Continuous contact between the pantograph and the overhead wire ensures the tram doesn't disconnect from the wire. Additionally, since the pantograph is mounted on a movable bracket, this bracket is key to preventing the tram from detaching from the wire and also serves as the tram's power switch. When the bracket is raised, the tram's pantograph receives power; when lowered, the tram loses power.

Why Does Poor Grounding Cause False High Water Temperature Readings?

Poor grounding leads to false high water temperature readings because the dashboard's temperature gauge shows an inaccurately high reading while the actual water temperature remains unaffected. Here are some extended details: 1. Grounding: Among the common causes of fire accidents due to electrical faults, poor grounding is the most significant factor. This is especially true for many new car owners who are overly protective of their newly purchased vehicles and thus install alarms, upgrade to high-end audio systems, or modify the vehicle's appearance. These modifications can potentially cause wiring grounding issues, leading to vehicle fires. 2. Precautions: Loose wiring connections or excessive local resistance can generate heat, causing wiring joints to overheat and ignite flammable materials. Additionally, vehicles in motion or during startup may sometimes experience backfire, which can also lead to fires. If the vehicle's engine lubrication system is low on oil, the friction between moving parts can generate high temperatures. Contact with flammable materials under these conditions can potentially cause a fire.

What does it mean when the ignition warning light turns red and then off?

Car ignition warning light usually comes on due to poor fuel combustion in the engine cylinders. Here are the relevant explanations: 1. Oxygen sensor: In automotive design, to ensure the engine operates in good condition and maintains normal working lifespan, an oxygen sensor is installed to monitor the engine's combustion status. Once poor combustion is detected, such as excessively high levels of hydrocarbons, carbon monoxide, or nitrogen oxides, these indicate bad combustion states that not only pollute the environment but also lead to fuel waste and excessive engine wear. 2. Solution: If the ignition warning light comes on, it is recommended to visit a repair shop for professional mechanics to diagnose and fix the issue.

What are the main differences between good and bad chassis?

The main differences between good and bad chassis are as follows: 1. Transmission: Power is transmitted from the engine flywheel, through the clutch, to the transmission. When evaluating a chassis transmission, first look at the type of transmission, common ones include CVT, automatic, dual-clutch transmission, and manual transmission. 2. Steering: Steering systems include hydraulic power steering, electro-hydraulic power steering, and electric power steering. For sedans, electric power steering is better, while for off-road vehicles, the first two provide greater assistance. 3. Suspension: Suspension systems are generally divided into double-wishbone, MacPherson, torsion beam, and multi-link types in terms of structure. Among them, MacPherson and multi-link belong to independent suspensions, which offer better handling and comfort than non-independent suspensions. For example, MacPherson suspension is mostly used for front wheels, belongs to independent suspension, has a simple structure, good space layout, and provides excellent driving stability. Therefore, most cars today use this structure.

Why Can't the Electric Car Door Open?

The following are the reasons why the car door cannot be opened: 1. Temperature: In the northern winter, the temperature is very low. If the water accumulated in the car lock, door frame, and handle is not dried after washing the car, it is easy to freeze, and the car door may not open in the morning. Some anxious owners may pull the door hard, not knowing that this can easily damage the car paint and seals, and in extreme cases, even break the door handle. 2. Child lock power failure: To protect children's safety, many car rear doors are equipped with child locks. When the child lock is engaged, the rear door cannot be opened from the inside and can only be opened from the outside handle. If the car happens to lose power at this time, the door cannot be opened from the outside either. 3. Remote control failure: The car remote control is the most frequently used car component by owners, and it can also malfunction, resulting in the car door not opening.
