It can be repaired, but it is recommended to directly replace it with a new tire. Even if the tire bulge is repaired, there is still a risk of tire blowout. A tire bulge occurs when the cord layer on the sidewall of the tire is damaged. It's important to know that this layer supports the entire tire's expansion and contraction. Once the steel wires inside are broken, the tire loses its protection, making it highly susceptible to blowouts. Below are the reasons for tire bulges: 1. Tire aging: If a tire is used for too long and exceeds its warranty period, it may age. Hitting a stone or speed bump while driving can cause a bulge. 2. Excessive tire pressure: Overinflated tires reduce the contact area with the ground, leading to premature wear. During use, rapid acceleration or poor tire heat dissipation can cause the tread temperature to rise, resulting in a bulge. If your tire has a bulge, it is advised not to continue using it. A bulged tire cannot be repaired or patched because the cord layer inside may have fractured. Even if repaired, the bulge may reappear after some time, posing a serious risk of blowout and creating significant hazards for vehicle operation.

What to Do When a Car Collision Occurs?

When a car collision occurs, the response should vary depending on the specific circumstances. Generally, it can be divided into the following scenarios: minor accidents with no casualties. These cases are straightforward and easy to resolve. Typically, the parties involved negotiate privately, with the at-fault party compensating the non-fault party for any damages. If negotiations fail, you can call the police (traffic police hotline 122, or dial 110) and notify the insurance company to arrive at the scene. Usually, the fully at-fault party will notify their insurance company. In cases of severe accidents with no casualties, it is mandatory to call the police and notify the insurance company. Wait for the traffic police to issue a liability determination report. For accidents involving casualties, first dial 120, followed immediately by 122 (traffic police hotline).

How to Deal with Fogging on the Outside of the Windshield in Summer?

Methods to remove fog from the outside of the windshield include opening windows for air circulation, using the air conditioning system, and applying defogging agents. Here are detailed introductions about car defogging: Opening Windows for Air Circulation: If the fog inside the car is not heavy, you can open the windows slightly to create air circulation between the inside and outside of the car. This reduces the temperature difference and gradually dissipates the fog. Air Conditioning System: Using the air conditioning system to remove fog is the most common method. Almost all cars on the market today have air conditioning vents located under the front windshield. Simply adjust the air conditioning to the appropriate setting to use the airflow to defog the windshield. Defogging Agents: Special defogging agents are widely available in auto parts stores and supermarkets. Spray the defogging agent onto the inner surface of the car glass and wipe it clean. This not only removes dirt from the glass but also forms a protective film to prevent moisture from condensing into a fog layer on the glass.

Will I get points deducted for driving at 60 in a 40 km/h ramp speed limit zone?

Driving at 60 in a 40 km/h ramp speed limit zone constitutes speeding, which will result in a 3-point deduction and a fine. Here are some precautions for driving on highway ramps: Reduce speed in advance: Before entering the highway ramp, you should slow down in advance, pay attention to the speed limit signs on the side of the ramp, and avoid overtaking on the ramp. Entering the main road: When approaching the ramp intersection, do not immediately enter the main road. Instead, first enter the acceleration lane to increase your speed to the required level, and then merge into the main traffic lane safely. Avoid missing the ramp exit: Before approaching the ramp from the main road, reduce your speed in advance, pay attention to the ramp signs, and avoid driving over the guide lines. Missing the ramp exit means you cannot make a U-turn and must exit at the next available exit.
