Can the replaced tires be sold?

Users can sell the replaced tires for money. Generally, the price of an old tire ranges from 5 to 40 yuan, depending on the condition of the tire. The old tires sold are processed as follows: Tire retreading, which is a technology that removes worn or otherwise damaged tires for reuse. Waste tires are refined by adding catalysts and other methods. The waste tire splicing technology is a technique that uses waste tires to extract fuel through heating, pressurization, and other methods. If simple and cheap equipment is used in this technology, it is easy to cause secondary pollution. Tire rubber powder reclaimed rubber, the tire rubber powder reclaimed rubber technology, uses waste tire rubber powder equipment to crush it into 20~30 mesh rubber powder, then desulfurizes the rubber powder to regenerate it into softened reclaimed rubber with arbitrary plasticity, which can be reprocessed into any rubber product. If the desulfurization process in the later stage is not technically sound, it is easy to cause pollution. Rubber powder is used for tire waterproofing and leak prevention, and waterproof membranes are mainly used for house leak prevention. Most houses now undergo waterproofing and leak prevention work. This industry is widespread across the country, and the usage of waterproof membranes is also very large. The rubber powder in this technology is also a main raw material, as waterproof membranes also belong to modified asphalt. If the old tires replaced are not sold for money, they can also be turned into treasures. For example, in some car-themed or environmentally themed parks, waste tires are transformed into colorful flower beds and swing chairs; in some amusement facilities, buffer walls made of spliced waste tires can often be seen, protecting our safety, and so on.

What should be paid attention to when driving for the first time?

Precautions for first-time driving: 1. Novices generally have a limited sense of speed, often unconsciously driving faster and faster. Combined with insufficient experience in handling curves, it's crucial to pay attention to roadside traffic signs, strictly adhere to speed limits, and slow down when seeing warning signs for curves to avoid skidding due to excessive speed. 2. Adjust your mindset, remember not to be nervous, and stay relaxed. 3. Plan your driving route. Unfamiliar roads are a major cause of accidents for beginners. Therefore, when heading to an unfamiliar area, consult a friend who knows the route well, clarify the driving directions, and note the turning points at key intersections.

What is the purpose of widebody kits?

Widebody kits are used to cover the wheels, preventing widened wheels from protruding beyond the body, which enhances aesthetics. Additionally, widebody kits offer certain aerodynamic benefits. Originally, widebody designs were first applied in racing cars. Race cars often feature widened wheelbases along with wider rims and tires to improve cornering stability and speed. In the civilian automotive sector, the primary function of widebody kits is aesthetic enhancement, allowing owners to install wider rims for superior visual impact. There are numerous brands that manufacture widebody kits, such as Rocket Bunny, LB, and RWB.

What Causes Severe Engine Vibration in Vehicles?

Vehicle engine vibration can be caused by the following reasons: 1. Mechanical engine failure, such as uneven cylinder pressure among cylinders; 2. Intake system malfunction, such as air intake pipe leaks, excessive carbon buildup on intake valves and pipes, or excessive dirt on throttle bodies and intake pipe walls; 3. Engine management system issues, such as incorrect coolant temperature or intake air temperature signals, or wiring faults; 4. Ignition system problems, such as excessive carbon buildup on spark plugs or incorrect gap settings, leakage in high-voltage wires or distributor caps, or damaged ignition coils; 5. Fuel supply system failure, such as injector sealing issues or clogging due to excessive internal carbon deposits in the nozzles.

What is the ECU in a car?

ECU is the onboard computer of a car. The ECU (Electronic Control Unit), also known as the onboard computer or vehicle computer. Functions of the ECU: It continuously monitors various input data (such as braking, gear shifting, etc.) and the operating states of the vehicle (acceleration, skidding, fuel consumption, etc.). It calculates the information sent by various sensors according to pre-designed programs, processes it, and then sends the parameters to relevant actuators to perform various predetermined control functions. Functions achievable by ECU remapping: Unleashing power. Generally, cars are conservatively tuned at the factory to balance fuel consumption, stability, and power. By uploading new rules, controlled parameters can be adjusted to unleash power. Improving functions, such as the oil dilution issue in certain models, can be addressed by remapping the ECU to adjust the fuel injection strategy and fix functional bugs. Turbocharged engines can increase output power by altering the turbocharging value. Due to market factors, the power of many models is limited at the factory. Remapping the ECU can lift these restrictions.

Why Doesn't the Reversing Camera Guideline Move with the Steering Wheel?

If the trajectory of the reversing camera does not move with the steering wheel, it may be due to an issue with the signal output from the host control unit, indicating a fault in the CAN transceiver interface circuit. Reversing Camera System: It displays real-time images from the vehicle's rear-view camera, providing the driver with a clear view of the environment behind the vehicle, facilitating parking and reversing. The reversing camera system mainly consists of a wide-angle camera installed at the rear, a control unit responsible for signal processing and transmission, and a display for viewing. Function: The reversing camera system is a safety aid for parking or reversing the vehicle. It informs the driver about surrounding obstacles through visual display, eliminating the hassle of checking around when parking, reversing, or starting the vehicle. It helps the driver overcome blind spots and unclear vision, enhancing driving safety.
