2.0 tire pressure is too low and may cause tire blowouts. The normal cold tire pressure should be between 2.2~2.5, with 2.5 generally recommended for better fuel efficiency and to ensure the tire pressure stays within the safe range of 3.0 during high-speed driving. Different vehicle models may have varying tire pressure requirements. Below are the functions of car tires: 1. Support the entire weight of the vehicle: Car tires bear the vehicle's load and transmit forces and moments in other directions. 2. Enhance vehicle performance: Car tires transmit traction and braking torque to ensure good adhesion between the wheels and the road, improving the vehicle's power, braking, and off-road capabilities. They also work with the suspension to absorb shocks and dampen vibrations during driving. 3. Prevent premature damage to vehicle components: Car tires protect vehicle parts from severe vibrations and early damage, adapt to high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.

As a veteran driver with twenty years of experience, I've witnessed too many accidents caused by tire pressure issues. A reading of 2.0 might seem moderate, but judging solely by the number can be misleading—it must be evaluated in the context of your specific vehicle. Every car has a recommended tire pressure value printed on a label located either on the tire sidewall or the door frame, typically ranging between 2.0 and 2.5. I remember back in my younger days when I drove an old car, I experienced a tire blowout due to low pressure. Since then, I've made it a habit to check my tire pressure monthly with a simple gauge, especially before long highway trips, to ensure consistency. In winter, as temperatures drop, tire pressure naturally decreases slightly, so it's better to top it up to around 2.2. When carrying heavy loads or passengers, you should also increase the pressure, as failing to do so can lead to unstable handling and increased fuel consumption. My advice? Don't cut corners—find a professional to check it regularly. Safety always comes first.

Can the driver's license exam be extended if it expires?

Whether the driver's license exam can be extended upon expiration depends on the specific circumstances. If it is due to personal reasons, it cannot be extended. However, if it is due to irresistible reasons such as the pandemic, the DMV will uniformly extend the validity period. For specific extension periods, please consult your local DMV, as the extension duration varies by region. Some DMVs have stated that they will provide separate notifications when exams resume, so there is no unified extension period. For example, some candidates scheduling exams on the Traffic Management 12123 app saw their exam validity extended by one year, changing from an original expiration date of January 15, 2022, to January 15, 2023. Due to the impact of the pandemic, most DMVs suspended driver's license exams from January to March. In regions where exams have just resumed, there may be a backlog of candidates due to previous pandemic-related delays, leading to potential congestion during scheduling. Candidates with a learning permit validity of less than six months can use the priority scheduling feature on internet platforms to arrange one priority exam for each subject within the validity period.

What are the differences between large and small tires?

The differences in tire size are: 1. Distance variation: Larger tires cover more distance per revolution of the connected driveshaft, while smaller tires cover less distance per revolution. 2. Traction difference: Larger tires have greater contact area with the road surface, enhancing vehicle traction; smaller tires have reduced contact area, resulting in weaker traction. Here are additional details: Tire classification: Automobile tires can be divided into pneumatic tires and solid tires based on carcass structure. Most modern vehicles use pneumatic tires, which are further categorized into high-pressure, low-pressure, and ultra-low-pressure tires according to internal air pressure. Low-pressure tires are commonly used across various vehicle types.

Will Car Stickers Be Penalized?

Car body stickers will not violate traffic regulations if they do not affect the vehicle's appearance or safe driving. Below are the precautions for stickers: 1. Car stickers cannot use the special colors designated for specific vehicles: firefighting red, engineering rescue yellow, and the upper white and lower blue color combination designated for national administrative law enforcement. These are special colors for specific vehicles and cannot be used on ordinary vehicles. Therefore, for the sake of personalization or other reasons, attempting to modify the vehicle with a full-body color-changing film (or other methods) constitutes illegal vehicle modification and will result in a fine of 500–1,000 yuan, along with an order to restore the vehicle to its original condition. 2. The area of car stickers must not exceed 30% of the vehicle's body area; exceeding this requires approval: If the area of car stickers is too large (exceeding 30%) and has not been reported to the public security traffic management department, it will cause the vehicle to differ from the photo on the vehicle registration certificate. This will be deemed illegal modification and will result in a fine of 500–1,000 yuan. Additionally, in the event of a vehicle accident, insurance companies may refuse to provide related compensation services for this reason. 3. Car stickers must not affect safe driving: The content must be healthy and positive.

Why Should You Avoid Flood-Damaged Cars?

Flood-damaged cars refer to vehicles that have been submerged in water. It is well-known that vehicles contain numerous mechanical components and various electronic parts. Currently, no vehicles on the market are completely sealed and waterproof. This means that when a vehicle is submerged in water, various components and electronic parts are bound to be damaged, leading to significant safety hazards. For example, the vehicle may stall at high speeds or experience brake failure. Metal Corrosion: Moisture-induced rust can occur as some metal fittings inside the vehicle are not treated with anti-corrosion measures. After repairs, residual moisture can accelerate the corrosion and oxidation of these metals. Damage to Electronic Control Components: Water damage can severely harm the vehicle's electronic control components, such as control modules and sensors for various systems, as well as electrical connectors, posing significant risks.

Can You Make a U-Turn on a Dashed Yellow Line?

Dashed yellow lines can be either double dashed yellow lines or a combination of one solid and one dashed double yellow line, and the specific situation must be analyzed. Double yellow lines can be either dashed or solid: double solid yellow lines (usually placed in the center of a two-way four-lane road or wider, often without a median or with a low median), double dashed yellow lines (usually placed on roads or intersections with lower traffic volume), or a combination of one solid and one dashed double yellow line. Below are the different driving requirements for these three types of road markings: 1. Double solid yellow lines: U-turns, crossing, or speeding turns are strictly prohibited. Violations will result in a 200-yuan fine and 3 demerit points. 2. Double dashed yellow lines: On main roads, left turns are allowed but U-turns are not, provided it is safe and does not obstruct traffic. 3. Combination of one solid and one dashed double yellow line: Vehicles on the dashed side can make U-turns or cross the line for turns if it is safe and does not obstruct traffic, while vehicles on the solid side cannot cross the line and must not remain on the double yellow line for an extended period.

What is the vehicle that mixes concrete called?

The vehicle that mixes concrete is called a mixer truck or can also be referred to as a concrete mixer transport truck. A mixer truck is a specialized truck used to transport construction-grade concrete; due to its shape, it is often nicknamed the "snail truck" or "olive truck." These trucks are equipped with a cylindrical mixing drum to carry the mixed concrete. During transportation, the mixing drum continuously rotates to ensure the concrete does not solidify. Below is an introduction to concrete mixer transport trucks: 1. Components: They consist of a truck chassis, mixing drum, transmission system, water supply device, full-power take-off, front and rear supports for the mixing drum, reduction gear, hydraulic transmission system, loading and unloading system, and control mechanism. The concrete mixer transport truck is composed of a truck chassis and specialized concrete mixing and transport equipment. 2. Working principle: Power is output from the full-power take-off of the second-class chassis and transmitted to the hydraulic pump via a drive shaft. The hydraulic pump generates hydraulic energy, which is transmitted to the hydraulic motor through oil pipes. The hydraulic motor converts hydraulic energy into kinetic energy, which is then transmitted to the mixing drum via a reduction gear to increase torque. By adjusting the servo handle angle of the (double-acting variable) hydraulic pump, the mixing drum's rotation direction and speed are controlled, enabling operations such as concrete loading, mixing, agitation, and unloading.
