How Many Years Can Car Tires Last?

Must all four tires be the same for vehicle annual inspection?

During the vehicle inspection, it is not mandatory for all four tires to have the same tread pattern. However, the two front tires (left and right) must be identical, and the two rear tires (left and right) must also be identical. The annual inspection requires that tires must not be excessively worn, and the tread patterns should not be inconsistent. It is acceptable for the rear two tires to be the same, but left and right tires must not differ. The functions of tires are: to transmit driving force, braking force, and steering force for vehicle operation; to support the vehicle load; and to reduce and absorb vibrations and impacts during driving. Methods for tire maintenance include: regularly cleaning stones from tire treads; minimizing exposure to direct sunlight; promptly checking tire pressure; paying attention to suspension maintenance; periodically inspecting front wheel alignment; and adopting careful driving practices, such as choosing smooth road surfaces and avoiding objects that could puncture or scratch the tires, as well as chemical spills that could corrode the tires.

Why can't the car start and the gear can't be shifted?

Here are the reasons why the car can't start and the gear can't be shifted: 1. No fuel: If the fuel gauge shows below the red line, the car naturally won't start. 2. Dead battery: This could be due to a drained battery from leaving the headlights on for too long or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, DVD players, etc., can also cause vehicle circuit failures. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: When starting an automatic transmission car, the gear must be in the P (Park) or N (Neutral) position. If it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars also won't start if the clutch isn't pressed.

Does Coasting in Neutral Save or Waste Fuel?

Coasting in neutral does not save fuel; sometimes it even consumes more and is detrimental to driving safety. Modern vehicles generally use fuel-injected engines controlled by the vehicle's ECU for fuel injection. If you choose to coast in neutral, the ECU will put the car into idle mode, which actually requires fuel injection to keep the engine running. Disadvantages of coasting in neutral: 1. Prone to stalling: Coasting in neutral can easily cause the vehicle to stall, which is harmful to the engine. Coasting in neutral should only be done under safe conditions and when the vehicle's technical condition is normal. It is prohibited to coast with the engine off, especially when going down steep or long slopes. 2. Reduced safety: Coasting in neutral significantly compromises safety. In fact, a vehicle's forward motion relies on the torque generated by the engine. Higher gears provide less torque, and throttle response becomes sluggish, slowing down acceleration. Therefore, the correct way to overtake is to downshift one gear. For automatic transmissions, simply pressing the accelerator pedal all the way down will cause the transmission to downshift one gear to provide sufficient torque.

Which part of the car is the hub?

Car hubs are wheel rims. Below is relevant information about wheel rims: 1. Introduction: The wheel rim is the rotating part of the tire's inner contour connected to the wheel steel via columns, i.e., the metal component at the center that supports the tire and is mounted on the axle. It is also called the wheel ring, steel ring, or tire bell. Wheel rims come in various types based on diameter, width, forming method, and material. 2. Size: The size of the wheel rim refers to its diameter. Generally, in passenger cars, larger wheel rim sizes with higher tire aspect ratios can create a visually appealing tension effect and improve the stability of vehicle handling. However, this comes with the additional issue of increased fuel consumption.

Is it necessary to apply film to the car windshield?

The front windshield of a car needs to be filmed for protection against outdoor UV radiation and visible light. Below is an introduction about the film: 1. Front Windshield: Modern car front windshields have adopted single-piece curved windshields, gradually phasing out flat-type windshields. Today's car windshields are generally made into a large curved single-piece design with certain curvatures on all sides. This type of curved glass is a product with very high technical requirements, whether from the processing or assembly perspective, as it involves issues such as vehicle model, strength, heat insulation, and installation. 2. Car Film: Car film (Auto-film) refers to applying a thin film-like object to the front and rear windshields, side windows, and sunroof of a vehicle. This film-like object is also called a solar film or heat-insulating film. Its main functions are to block UV rays, partially block heat, prevent injuries caused by glass shattering, reduce glare, and, based on the one-way transparency feature of the solar film, achieve the purpose of protecting personal privacy.
