What does the 'R' on tires mean?

The 'R' on tires stands for radial tires. Here is an introduction to the related content: 1. English abbreviation: 'R' is the abbreviation of the English word 'radial'. 2. Tire classification: According to their structure, car tires can be divided into radial tires and bias tires. 3. Representation: In tire specifications, 'R' indicates that the tire type is a radial tire, while bias tires are represented by the letter 'B'. Below is an introduction to the 27.5×1.95 tire comparison table: 1. Diameter: 27.5 is the diameter of the rim. 2. Width: 1.95 is the width of the outer tire. 3. Outer tire: The diameter of the rim increases when the outer tire is added. 4. Wheel circumference: The circumference of a 27.5×1.95 wheel is 2115mm. 5. Meaning of numbers: 27.5 inches refers only to the diameter of the steel rim and does not include the width of the outer tire. 6. Parameter settings: The recommended parameter setting for a 27.5×1.95 tire speedometer is 2155.

What do kg/cm2 and bar mean on a tire pressure gauge?

Tire pressure bar is the imperial unit of pressure "bar", which is one of the units for measuring tire pressure. 1 bar = 1 ATM (standard atmospheric pressure). In addition to bar, other units for tire pressure include kPa (kilopascal), psi, and kg/cm2 (kilogram pressure). The conversion formula between them is: 1 bar = 100 kPa = 14.5 psi = 1.02 kg/cm2. The following factors should be considered when adjusting tire pressure: 1. Seasonal factors: In winter, the tire pressure can be appropriately increased by about 0.2 bar based on the standard tire pressure. In summer, the lower limit of the standard tire pressure should be followed. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. 2. Road conditions: On roads with significant bumps, the tire pressure can be appropriately reduced by 0.1-0.2 bar based on the standard tire pressure. For roads with minor bumps, this can be ignored. For long-distance high-speed driving, the tire pressure should not be too low and can be appropriately increased by about 0.2 bar based on the lower limit of the standard tire pressure.

How to Eliminate Door Squeaks by Adding Lubricating Oil?

Adding lubricating oil to the joints in the door gaps can eliminate door squeaks. You can also use grease or engine oil, as 4S shops use liquid grease to achieve lubrication. Be careful not to add too much, as it may attract impurities. Doors and the car body are connected via hinges, and it is normal for hinges to make noise after prolonged use. To ensure the hinges remain smooth and quiet for a long time, you can regularly add lubricating oil every 2-3 months for maintenance. After extended use, the friction in the hinges increases, leading to abnormal noises. Therefore, what you need to do is spray automotive rust inhibitor on the hinges and then apply a small amount of grease, which will significantly reduce friction and eliminate door squeaks. Abnormal noises caused by door seals. With prolonged use, the door seals themselves gradually age, causing friction between the door seals and the car body, which may result in abnormal noises while driving. Another possible cause of door squeaks is loose door screws or window lift brackets. When driving on bumpy roads, the car windows may produce squeaks, which are likely due to loose screws or lift brackets inside the window glass. In such cases, you need to visit a repair shop to tighten the screws.

How to Deal with Abnormal Noise When Raising and Lowering Car Door Windows?

There are several methods to address abnormal noise when raising and lowering car door windows, including cleaning the window guide channels, applying window lubricant, and performing window initialization. Car owners should maintain their windows properly and address any abnormal noise promptly to prevent damage to the glass. Methods to deal with abnormal noise when raising and lowering car door windows: Clean the window guide channels: The abnormal noise occurs because dust accumulates in the rubber guide channels of the windows, increasing resistance and causing the noise. The solution is to clean the guide channels. Prepare a cloth and a chopstick. Wet the cloth, wrap it around one end of the chopstick, and secure it with a rubber band. Then, insert this end into the guide channel and slide it back and forth to clean until no more dirt comes out. Use window lubricant: If the rubber in the window guide channels has aged, it may cause slight hesitation and abnormal noise when raising or lowering the window. Use window lubricant to address this issue. Lubricant is inexpensive, lasts a long time, and is easy to apply—simply spray it onto the rubber. Window initialization: If the window not only makes noise but also moves with difficulty, tilts to one side, or does not respond when raised or lowered, the issue may be due to lost initialization data. Performing a window initialization can resolve this problem.

What to Do When the Engine Malfunction Light Comes On in a New Car?

If the engine malfunction light comes on, you can follow these steps to address the issue: First, check whether the engine is running normally, such as if there is shaking, black smoke, or difficulty starting. If any of these issues are present, avoid restarting the engine. Note: If the light is red, do not restart the engine under any circumstances. If the engine is running normally and the car can be driven, take it to a service center as soon as possible to diagnose the problem. The service center can easily read the fault codes using a portable diagnostic tool and perform targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting various wiring harness connectors, as a loose connection may be the cause. Alternatively, repeatedly turning the key to the ON position may reset the light. Generally, the engine malfunction light may come on due to the following seven reasons: Sensor failure: Sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, and oxygen sensor may become damaged, have poor contact, or lose signal transmission. When the car's ECU cannot accurately obtain engine data, the malfunction light will illuminate. Fuel or oil quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear and trigger the malfunction light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When the oxygen sensor detects this and reports it to the ECU, the malfunction light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion. Turbocharger problems: The intake boost pipe or turbocharger can also trigger the engine malfunction light. The most common issue is a damaged turbocharger, which may also cause symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the car's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the malfunction light will illuminate. A dirty air filter that hasn't been cleaned regularly can cause intake issues. Exhaust problems: Exhaust system faults can also trigger the engine malfunction light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit, often due to the use of leaded gasoline, lead- or silicon-containing lubricant additives, physical damage, or fuel system issues. Anti-theft system failure: If the car's electronic anti-theft system malfunctions or the anti-theft controller is incompatible with the engine ECU, the anti-theft system may prevent the engine from operating normally and trigger the malfunction light.
