Should the Spare Tire Be Installed on the Front or Rear Wheel?

Spare tires can be installed on either the front or rear wheels. Definition of a Spare Tire: A spare tire refers to the backup tire for a car, typically matching the specifications of the original tires. However, some vehicles may use spare tires with special-colored rims, compact spares, foldable spares, or run-flat tires to remind the owner to inspect and replace faulty tires promptly. Types of Spare Tires: Regularly inspect the spare tire, focusing on tire pressure, wear, and cracks. Replace the tire before the tread wears down to the wear indicator line. Avoid storing oil products near the spare tire, as rubber—the main component of tires—is highly susceptible to damage from oil exposure. Many car owners store lubricants and other oil products in the trunk, which can cause tire swelling and significantly reduce the tire's lifespan if they come into contact with the tire. Spare tires typically last about four years. It’s common for owners to discover that their spare tire has severely aged and become unusable after years of storage when they need it for a flat tire. Since tires are rubber products, prolonged storage leads to aging, with a general aging period of around four years. Avoid prolonged use of the spare tire, as it can negatively impact the vehicle's braking system, steering system, and suspension, posing safety risks and causing uneven wear on other tires in the same direction.

Can I make a U-turn at a dashed line when the left-turn arrow is red?

If the dashed line is set before the stop line at the intersection and there are no other signs prohibiting U-turns, you can directly make a U-turn at the dashed line without being controlled by the traffic signal, provided it does not affect other vehicles. Other situations where U-turns are prohibited are as follows: U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If the intersection permits U-turns, you must cross the crosswalk before making a U-turn; you cannot make a U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, U-turns are not allowed if there is no sign permitting left turns. U-turns are prohibited in the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any directional signs, vehicles can only make U-turns in the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line before making a U-turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and 12 penalty points. If you miss an exit on the highway, continue to the next exit and leave the highway; never attempt an illegal U-turn.

How to Determine if a Car is Burning Oil?

Oil burning in vehicles is related to poor cylinder sealing and the driving habits of the driver. Here are three methods to self-check if your car is burning oil: 1. Cold engine oil burning: When starting the car for the first time in the morning, thick blue smoke appears from the exhaust pipe, which disappears after a while. This phenomenon may not recur that day but reappears the next morning or the morning after, indicating oil burning. This is called cold engine oil burning. 2. Acceleration oil burning: When driving or idling, if the driver steps hard on the accelerator and a large amount of blue smoke is emitted from the exhaust pipe, it indicates a more severe oil burning condition. This is called acceleration oil burning. 3. Pulsating blue smoke from the oil filler cap: In addition to blue smoke from the exhaust pipe, pulsating blue smoke can also be seen coming from the oil filler cap. In this case, the engine damage is already quite serious.

How many days does it take to check traffic violations?

Generally, it takes 3 to 7 days to check traffic violations after they occur. Below are specific explanations for querying vehicle violation information: 1. Vehicle violation behavior: If penalties are required according to regulations, the public security network usually publishes the violation information within 7 working days. 2. Driving a vehicle with violation behavior: The processing time cycle for electronic monitoring by traffic police is approximately 3-5 working days. Whether the vehicle is involved in a violation can usually be checked after a week. If no results are found, it can generally be confirmed that there is no violation. 3. Cross-province, city, or autonomous region violations: The time for publishing violation information refers to the scope within the province, city, or autonomous region. If the violation occurs across provinces, cities, or autonomous regions, the query time may extend to more than 15 working days.

What Are the Reasons for a Car Starter Not Starting?

Reasons why a car starter does not start: 1. Insufficient battery power; 2. Poor contact of the ignition switch; 3. Starting circuit failure, etc. Solutions: Most cases are caused by insufficient battery power. You can first observe the dashboard, check the brightness of the headlights, the sound of the horn, and the battery discharge inspection hole to determine whether it is a battery fault. Below is an introduction to the starter and engine: 1. Starter: It converts the electrical energy of the battery into mechanical energy to drive the engine flywheel to rotate and start the engine. Before the engine can run on its own power, it must rely on external force to rotate. 2. Engine: The process by which the engine transitions from a stationary state to self-operation with the help of external force is called engine starting. Its working principle is based on the Ampere's Law energy conversion process, where a current-carrying conductor is subjected to force in a magnetic field.
