The tires of the Mercedes-Benz C are run-flat tires. Introduction to run-flat tires: Run-flat tires are technically known as "Self-Supporting Run-flat Tires," abbreviated as RSC. The sidewall of an inflated tire is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width). The sidewall is very "thick," and a severe "blowout" usually causes an instant collapse of the sidewall, leading to an immediate loss of support from the tire. This results in an instant shift in the vehicle's center of gravity, particularly for front-wheel-drive cars where a front tire blowout can cause a sudden shift in the center of gravity, potentially leading to loss of vehicle control. Introduction to the new C-Class: The new C-Class sedan is equipped with an active safety system, intelligent lighting system, preventive safety system, passenger safety protection system, and rescue tools, making it comfortable, refined, practical, and top-notch in safety.

To be honest, I also drive a Mercedes-Benz C-Class, and this question depends on the specific situation. Not all original tires on the Mercedes-Benz C-Class are run-flat tires; it mainly depends on the specific configuration and the year of purchase. Newer Mercedes-Benz C-Class models are more likely to come standard with run-flat tires, while older base models might use regular tires. Run-flat tires usually have markings like RSC or MOE on the sidewall—just check the tire sidewall to confirm. The biggest advantage of run-flat tires is that if you get a puncture, they can still support the car for about a hundred kilometers to reach a repair shop, which is crucial for driving safety. However, run-flat tires are noisier and slightly less comfortable than regular tires, and they also cost more to replace. If your car was purchased with a sports package, it’s almost certainly equipped with run-flat tires.

I just helped my relative pick up a Mercedes-Benz C260 at the 4S dealership and specifically asked the salesperson about the tires. He said most vehicles now come with run-flat tires from the factory, more accurately called 'tire pressure monitoring system tires'. The most noticeable feature of these tires is their stiffness - the sidewalls are extremely thick and rigid, barely budging when pressed with a finger. The advantage is that they won't immediately collapse during a high-speed blowout, allowing the vehicle to continue driving while supporting the car's weight. However, the downside is that repairing them is troublesome; if a nail punctures the tread, you'll need to visit a specialized shop as regular repair shops might not handle them. Also, note that run-flat tires have a lifespan too - they must be replaced when worn to the warning line, don't assume they last forever. I suggest you check the trunk: if there's no spare tire and only tire sealant is provided, it's definitely a run-flat tire. If you feel excessive bumpiness when going over speed bumps while driving, that's also a typical characteristic of run-flat tires.

Having worked in car repairs for over a decade, I've seen plenty of tire issues with Mercedes C-class. The run-flat tire situation depends on the wheels - factory 19-inch rims usually come with run-flats, while 18-inch ones might be mixed. The identification method is simple: kick the tire sidewall before starting the car - run-flats feel hard as rock. Their biggest advantage is safety, allowing directional control after a blowout, especially suitable for frequent highway drivers. However, daily maintenance requires two precautions: first, avoid direct high-pressure water jet at the wheel hub center to prevent damaging the air pressure sensor; second, maintain tire pressure about 0.2bar higher than regular tires. When replacing, always change in pairs with identical brand and model - never mix four different tires as this affects Mercedes' preventive safety system.

Does a new car need maintenance at 3,000 kilometers?

For a new car, maintenance is required either 3 months from the date of purchase or at 5,000 kilometers, whichever comes first. Once either condition is met, the car should be taken to a 4S shop for maintenance. The first maintenance is free within the specified period, but any maintenance beyond the first one will require payment. If maintenance is not performed as required, the 4S shop may consider it as voluntarily waiving the warranty rights, which is not cost-effective because the nature of the vehicle warranty is similar to buying insurance for the vehicle. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.

Are New Energy Vehicles Exempt from Vehicle and Vessel Tax?

For eligible new energy vehicles, there is no need to pay vehicle and vessel tax. According to Article 2 of the "Notice on Preferential Policies for Energy-Saving and New Energy Vehicles and Vessels Regarding Vehicle and Vessel Tax": New energy vehicles and vessels are exempt from vehicle and vessel tax. New energy vehicles exempt from vehicle and vessel tax include pure electric commercial vehicles, plug-in (including range-extended) hybrid vehicles, and fuel cell commercial vehicles. Pure electric passenger vehicles and fuel cell passenger vehicles are not subject to vehicle and vessel tax and are exempt from it. Below are the benefits of new energy vehicles: 1. Fuel energy savings: New energy vehicles generally use natural gas, petroleum gas, hydrogen, or electricity as power sources, saving fuel energy. 2. Reduced exhaust emissions: New energy vehicles produce no exhaust emissions, effectively protecting the environment. Electric vehicles do not emit tail gases and are pollution-free. Hydrogen-powered vehicles emit water as exhaust, which causes no environmental pollution. Since they are essentially zero-emission, they are also exempt from traffic restrictions based on license plate numbers. 3. High efficiency: New energy vehicles generally adopt new technologies and structures, making them more efficient.

Do You Need to Keep Pressing the Accelerator When Driving at a Constant Speed?

When driving, you still need to continue pressing the accelerator after reaching a steady speed; otherwise, the speed will gradually decrease until the vehicle stops. Below is relevant information about pressing the accelerator in a car: Proper Techniques for Pressing the Accelerator: The engine's accelerator is typically controlled by a pedal, also known as the throttle pedal, which regulates the fuel supply to the vehicle's engine. To operate the accelerator pedal, place the heel of your right foot on the floor of the driver's compartment as a pivot point, then gently press the accelerator pedal with the ball of your foot, using ankle movements to press down or release. When pressing or releasing the accelerator pedal, apply force gently, ensuring a smooth and gradual motion. Precautions When Pressing the Accelerator: When driving uphill, avoid pressing the accelerator pedal all the way down. When using a low gear, it is generally advisable to press the accelerator halfway. Similarly, avoid pressing the accelerator pedal fully when climbing a slope. If the engine does not respond with increased speed after pressing the accelerator three-quarters of the way while driving, shift to a lower gear and then press the accelerator to accelerate.

What are the effects of larger tire sizes?

Tire sizes that are too large will result in shorter mileage, failure to pass annual inspections, increased fuel consumption, and may lead to phenomena such as 'tire wear' or 'pulling to one side,' as well as reduced tire lifespan. Specific effects of larger tire sizes: Original tires are more in line with fuel consumption standards. Larger tires mean increased weight, leading to higher fuel consumption during driving. Mileage becomes shorter because as the tire and rim size increase, the tire's diameter and radius lengthen, increasing the circumference. This results in a reduced rotation speed and noticeable changes in the distance covered per rotation. Failure to pass annual inspections is due to Article 16, Section 1 of the 'Road Traffic Safety Law of the People's Republic of China,' which states that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Precautions for replacing car tires: When selecting tires, the specifications must match the previous tires and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing tires, the aging cycles of the new tire and valve stem differ. During the new tire's lifespan, the valve stem may develop issues that are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Installation direction and inflation: If using original equipment tires, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. For directional tires, align the arrow on the wheel with the car's forward direction. When inflating, fill to the maximum pressure allowed by the tire, then reduce to the manufacturer's specified standard pressure.
