Can a slightly bulging tire be repaired?

Tires with slight bulges can be repaired, but they need to be replaced directly. Continued use may easily lead to tire blowouts, endangering driving safety. The functions of tires are: 1. To transmit driving force, braking force, and steering force through the tires to achieve vehicle operation; 2. To support vehicle loads; 3. To reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Situations that require tire replacement include: 1. Tire deformation; 2. Severe damage to the tire body; 3. Severe damage to the tread; 4. Damage to the bead; 5. Bulging or cracking on the tire sidewall; 6. Damage caused by driving with insufficient tire pressure; 7. Tires that have been patched more than three times; 8. Tires worn to the wear limit; 9. Chemical corrosion; 10. Severe aging and peeling.

What Are the Reasons for Car Shaking When Braking?

The reasons for car shaking when braking are: 1. Uneven brake disc surface with excessive radial runout; 2. Significant deviation in wheel alignment data; 3. Tire pressure being too high or too low; 4. Abnormal tire wear; 5. Wheel rim deformation. The function of brakes is to reduce speed or bring the vehicle to a stop. The working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle. Brake maintenance methods include: 1. High-temperature resistance protection to prevent brake system corrosion, avoid brake pad seizure due to high temperatures, and eliminate brake pad squealing; 2. Regularly replacing brake fluid; 3. Cleaning oil stains, dirt, and friction dust from brake discs, brake drums, and any related parts to ensure good heat dissipation of the brake discs; 4. Regularly checking the thickness of brake pads or brake shoes.

What Are the Causes of a Car Going Out of Control?

The causes of a car going out of control are: 1. Malfunction of cruise control, leading to the inability to operate the brakes, accelerator, and steering; 2. Issues with the steering linkage causing the steering wheel to lose control; 3. Brake failure resulting in the car going out of control; 4. Severe tire wear or sudden tire punctures and blowouts causing the car to lose control. The solutions for a car going out of control are: 1. Turn on the hazard lights and try to stop the car before a turn; 2. Check if there is any malfunction in the cruise control; 3. Inspect the steering linkage for issues and promptly visit a 4S shop for repairs if problems are found; 4. Check the brakes for any malfunctions and replace them if necessary; 5. Examine the tires for severe wear or blowouts.

What Causes Engine Shaking When Starting a Car?

Engine shaking when starting a car can be attributed to the following reasons: 1. Severe engine carbon buildup: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits; 2. Dirty throttle body or excessive carbon buildup on the fuel injectors; 3. Engine misfire: This mainly refers to one or more cylinders in the engine not functioning properly; 4. Unstable combustible mixture in the engine, causing idle shaking after a cold start. 5. Additional information: An engine is a machine capable of converting other forms of energy into mechanical energy, which can be used either as a power generation device or to refer to the entire machine including the power unit.

What does 245/45r18 mean?

The meaning of the car tire 245/45r18 is as follows: 1. 245: 245 represents the tire section width, the unit is mm, generally the width of the tire is between 145 to 285mm, with intervals of 10mm. 2. 45: 45 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, 45 represents forty-five percent, the aspect ratio of the tire is between thirty to eighty percent. 3. R: R indicates that the tire has a radial structure. 4. 18: 18 is the outer diameter of the wheel axle, the unit is inches. Additional information: Under normal circumstances, ordinary cars should not use tires with an aspect ratio greater than seventy-five percent, luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio less than sixty percent.

How to Check if the Car Coolant is Low?

Here are the methods to check if the car coolant is low: 1. Always check the coolant when the engine is cold. The radiator should be completely filled with coolant, while the expansion tank should be filled to about 70% of its capacity. 2. Check the MIN and MAX marks on the car radiator. The coolant level should be between the MAX and MIN marks, indicating it is at the normal level—neither too much nor too little. 3. If the level is below MIN, it means the coolant is insufficient and needs to be topped up promptly. It is best to add dedicated coolant. In emergency situations, distilled water can be added, but it must be completely replaced before winter if mixed with distilled water.
