Tire RFT is not a run-flat tire. The following is an introduction to the functions of tires: 1. Weight: Supports the entire weight of the vehicle and bears the load of the car. 2. Transmission: Transmits traction and braking torque, ensuring the adhesion between the wheels and the road surface. 3. Reduction: Reduces and absorbs the vibrations and impact forces during driving, preventing severe vibrations and premature damage to automotive components. 4. Adaptation: Adapts to the high-speed performance of the vehicle and reduces driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.

I experienced the power of RFT run-flat tires firsthand. I remember one time driving to the suburbs when my tire got punctured. The dashboard alerted me about low tire pressure, but I was still able to drive steadily to a nearby repair shop. The mechanic said the RFT design helped me avoid the risk of an emergency roadside tire change, saving me a lot of trouble. The downside is slightly more noise, especially noticeable on rough roads, and the slightly heavier weight might affect fuel efficiency a bit. Maintenance tip: Check tire pressure quarterly to ensure it meets standards, as RFT tires are more sensitive to leaks, and insufficient pressure can affect their run-flat capability. Overall, as a daily commuting tool, these tires enhance convenience and safety, and I highly recommend them to car owners who prioritize hassle-free driving.

When it comes to run-flat tires, I think the RFT marking is quite clear. It's the type that can continue driving after a puncture, thanks to its reinforced sidewall structure that bears the load. The benefits are obvious: in case of a flat, you don't have to get out of the car, significantly improving safety, especially in bad weather or on highways. However, the replacement cycle is shorter, typically around 5 years; and the cost is higher, with each tire costing over 100 yuan more than a regular one. During use, it's important to avoid excessive wear, such as driving too fast over potholes, which could damage the sidewalls and impair functionality. Regular checks of tread depth are also necessary. From a maintenance perspective, choosing a professional shop for installation is crucial to ensure proper wheel rim matching and avoid the risk of detachment.

How many kilometers does a new car need to change tires?

Car tire replacement is influenced by various factors such as mileage, tire quality, road conditions, and driving style. Generally, tires should be replaced after about 60,000 to 80,000 kilometers for optimal performance. The service life and mileage of tires are usually only for reference. In actual use, car owners mainly judge whether to replace tires based on their specific conditions, with the tire surface tread being the most intuitive method. When the tread depth wears below 1.6 millimeters, the tire needs to be replaced. Severe tread wear significantly reduces the tire's grip and drainage performance, compromising safety, making the vehicle prone to skidding, increasing braking distance, and raising the risk of accidents. Some tires have wear limit indicators; when the tire wears down to the level of the indicator, it needs to be replaced. Tires that show cracks or bulges also need to be replaced promptly. Generally, these conditions indicate that the tire is damaged and poses a safety hazard. Avoid high-speed driving and replace the tire as soon as possible. Tire maintenance: During routine car maintenance, it is essential to develop good habits of checking, cleaning, and maintaining tires; avoid sudden braking or rapid acceleration that can burn the tires, and perform timely tire rotation to effectively extend tire life and potentially increase the mileage the tires can cover.

What engine does the Arrizo GX use?

The Arrizo GX is equipped with the SQRE4G15C engine, which delivers a maximum horsepower of 116 HP, a maximum power output of 85 KW at 6150 rpm, and a peak torque of 143 N.m. The vehicle's power performance is smooth, and it is well-known for its low fuel consumption and maintenance costs. The engine of the Arrizo GX is independently designed and developed by Chery, making it a domestically produced engine. For daily maintenance of the Arrizo GX's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be chosen according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts can precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What is the normal tire pressure for a Malibu car?

The normal tire pressure range for a Malibu is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard. The Malibu does not come with a tire pressure monitoring system from the factory. It is recommended to purchase a tire pressure gauge, locate the position of the original tire pressure label, press the gauge onto the tire valve to measure and read the pressure, and remember to replace the valve cap after measurement. Additionally, a tire pressure monitoring system can be installed. Generally, a tire pressure above 2.8bar is considered too high, and a tire pressure below 2.0bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread of the tire, shortening tire lifespan; increased body vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire elasticity, and increasing the load on the car during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, which are unfavorable for driving safety; increased movement of various parts of the tire, leading to abnormal heat generation due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplied friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure. Usually, an alarm is triggered when the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are needed. Tire pressure monitoring not reset. After inflating the tires, the tire pressure was not reset in time, causing the tire pressure monitoring system to still record the previous data, and the tire pressure monitoring indicator light will remain on. In this case, simply reset the tire pressure. Damaged tire pressure sensor. The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation valve. If the sensor is damaged while driving, the tire pressure warning light will also come on. For sensor damage issues, only a new replacement part can be used.

Why Replace the Original Engine Number?

Changing the original engine number means replacing the engine. When the engine noise is very loud, it is necessary to replace the engine: After replacing the engine, there is no need to change any procedures because the engine number remains the same. For future vehicle inspections or transfers, only the chassis number is checked, not the engine number. Precautions for engine replacement: After replacement, the engine number must be reported to the vehicle management office to update the vehicle information for future annual inspections. Another method is to replicate the original engine number from the replaced engine onto the new engine. This way, the vehicle management office's records do not need to be updated.

Is the first traffic violation for a new car exempt from penalties?

New cars are not exempt from penalties for their first traffic violation. Notification time limit: After a traffic violation, you will generally receive a violation notification via text message within 3-7 days. According to traffic laws, violations are usually recorded online or via SMS notification within 3 to 7 days, with a maximum delay of no more than 13 working days. On-the-spot penalties: If you are stopped by traffic police on-site and sign the violation confirmation, you must report to the local traffic police department within 15 days of the violation. Failure to do so within this period will result in a daily late fee of 3%, although the total late fee will not exceed double the original fine amount.

What Causes Idle Vibration in the Edge?

The reasons for idle vibration in the Edge are as follows: 1. Engine intake pipe leakage: The intake system contains numerous intake manifolds or various valves. Leakage in these components can allow unintended gases to enter, leading to excessively high or low concentrations of the air-fuel mixture in the intake manifold, ultimately causing intermittent engine vibration or weak idle performance. 2. Fuel system blockage or malfunction: Blockages in the fuel tank vent, fuel tank switch, fuel filter, or the fuel line between the fuel tank and carburetor can prevent the engine from receiving the required amount of fuel during idle, resulting in a lean air-fuel mixture, weakened engine power output, and idle vibration.
