Do Cars Have Inner Tubes and Outer Tires?

Most household cars nowadays use tubeless tires, which consist only of outer tires without inner tubes. Tubeless tires are primarily used for small and medium-sized vehicles and motorcycles, offering excellent shock absorption and grip, with minimal damage and no immediate loss of air pressure. Inner and outer tubes are mainly used in bicycles and large vehicles, known for their durability and load-bearing capacity. Lifespan of Car Tires: Generally, tires last for 3-5 years. Regular maintenance is essential, such as checking for bulges, cracks, cuts, punctures, or abnormal wear on the tire tread. Using damaged tires can lead to increased safety risks during driving. Car Tire Maintenance Methods: Regularly remove stones stuck in tire grooves, minimize exposure to direct sunlight, monitor tire pressure promptly, maintain suspension systems, check front-wheel alignment periodically, and adopt careful driving habits. Choose smooth roads to avoid objects that could puncture or damage tires, and steer clear of chemical spills that may corrode tires. Tire Replacement Guidelines: Same specifications: Tires of different sizes have varying inflated outer diameters and section widths, leading to uneven load distribution if mounted on the same axle. Same structure: Radial and bias-ply tires differ in carcass construction, affecting cushioning performance and axial deformation. Mixing these types on one axle results in uneven load distribution and wear. Same tread pattern: Different tread patterns not only cause uneven wear but also affect ground adhesion. Mismatched tread patterns on left and right tires can compromise vehicle stability and lead to swerving or fishtailing during emergency braking.

How many kilometers should the timing chain be replaced?

There is no unified standard for how many kilometers the timing chain should be replaced, as the usage and maintenance conditions of each vehicle greatly affect the lifespan of the timing chain. A well-maintained timing chain can last for over a hundred thousand kilometers, or even several hundred thousand kilometers without failure. However, if the timing chain is not used or maintained properly, there is still a possibility of breakage or detachment. It is recommended to regularly inspect and maintain the timing chain, allowing professional technicians to determine whether it needs replacement based on the actual condition of the vehicle. The replacement cycle for coolant is every two years, which can be extended to three years if the vehicle is not used intensively. If there are abnormal changes in the color or smell of the coolant, or if water has been added to the coolant, it should be replaced as soon as possible.

How long does it take to check for traffic violations?

Generally, it takes 3 to 7 days to check for traffic violations after they occur, and no more than 13 working days. Violations recorded by electronic monitoring usually require manual review. For violations on highways, the review process is generally faster, and sometimes the violation record can be checked the next day. Violations on ordinary roads take slightly longer. Since violations recorded by electronic monitoring do not come with paper notices, the traffic management department usually sends SMS notifications or mails letters to inform the vehicle owner. Traffic violations refer to the actions of vehicle drivers, pedestrians, passengers, and other individuals or units related to road traffic activities that violate the Road Traffic Safety Law of the People's Republic of China, as well as related laws, regulations, and traffic management rules.

Is it no longer necessary to display the insurance sticker?

Whether the insurance sticker still needs to be displayed depends on the regulations of the local traffic authorities. Regions such as Beijing and Shenzhen have taken the lead in implementing the electronic insurance policy policy. Vehicle owners who purchase electronic insurance policies no longer need to display the insurance sticker on their car windows, as traffic police can verify insurance coverage through online checks. In other words, in these areas, the insurance sticker is no longer required. After the implementation of electronic insurance policies, individuals no longer need to provide paper proof of compulsory traffic insurance when handling traffic management procedures within the province. During traffic law enforcement, confirmation is made by real-time verification of the vehicle's compulsory traffic insurance information. Vehicles with valid insurance will not be penalized or impounded. For vehicle registration and inspection, the comprehensive platform checks the compulsory traffic insurance information, eliminating the need for paper proof. When handling accident cases, traffic police can confirm relevant insurance information by querying the electronic insurance policy.
