What is the difference between tubed and tubeless tires?

1 Answers

07/29/25 10:24pm
Tubed and tubeless tires differ in the following aspects: 1. Safety: Tubeless tires have a layer of rubber on the surface. After inflation, the surface tension increases, creating a certain pressure. Even if punctured, they do not deflate instantly and offer better flexibility. Tubed tires, on the other hand, have poorer safety as the inner tube is in a stretched state inside the tire and can easily form small holes when slightly punctured, leading to rapid pressure loss. 2. Durability: The rim diameter of tubeless tires is larger than that of regular tires. Without an inner tube or liner, the tire and rim are sealed as one unit. When the vehicle is driven at high speeds, the heat generated by friction between the tire and the road surface is dissipated directly through the rim, quickly reducing the tire temperature and thereby extending the tire's lifespan.

What to Do When Push-Button Start Fails to Ignite?

The solution for a push-button start failing to ignite is to pick up the smart key and place it on the start button, then press the button to start. Below are precautions for push-button start in cars: 1. Steering wheel lock: When the engine start/stop button is in the OFF position, the steering wheel locks as an anti-theft measure; when the door is opened or the smart key is removed from the smart key cylinder, the steering wheel will automatically lock. Normally, when the engine start/stop button is in the ACC position, the steering wheel will automatically unlock. If the steering wheel does not unlock normally, you can release the tension by turning the steering wheel left and right while pressing the engine start/stop button to unlock the steering wheel. 2. Turning off the engine while driving: In case of an emergency while the vehicle is in motion, you can turn off the engine by pressing the engine start/stop button for more than 3 seconds or pressing it three times consecutively, at which point the power switches to the ACC state.

Can the car still be used if the oil hasn't been changed for nine months?

It is possible to use the car if the oil hasn't been changed for nine months, but engine oil needs to be replaced regularly and cannot be used indefinitely. The replacement interval is determined based on the quality grade of the oil: 1. Fully synthetic oil should be replaced approximately every 10,000 kilometers or once a year; 2. Semi-synthetic oil should be replaced approximately every 7,500 kilometers or every seven to eight months; 3. Mineral oil should be replaced every 5,000 kilometers or every six months. Long-term failure to change the oil can cause certain damages to the car: 1. It can cause the oil to become watery, leading to a loss of sealing between the cylinder block and piston; 2. The lubrication effect decreases, affecting the engine's performance and lifespan; 3. It can lead to sludge formation. When there is too much sludge in the engine, the oil pump may struggle to maintain sufficient oil pressure, which can cause engine failure.

What is the auto-stop function?

Autostop refers to the automatic stopping of the engine. When the engine stops automatically, the tachometer needle will point to the autostop position. Here is the relevant introduction: 1. Function of auto start-stop: The auto start-stop system has become increasingly popular in recent years, helping to reduce exhaust emissions and save fuel. When the engine auto start-stop function is turned on, the engine will automatically shut off when the vehicle is moving at low speed or is stationary. 2. How to use: Pressing the start-stop function button on the car can turn the function on or off. When the vehicle speed is low or the vehicle is stationary, shifting the gear lever from D to neutral and pressing the brake will cause the engine to stop automatically. The tachometer needle will point to the AUTOSTOP position.

How are the grades of automotive engine oil classified?

Oil grades are classified based on the quality level of the oil, with the standard using the letter "S" to represent oil for gasoline vehicles. Different grades of oil are then arranged in alphabetical order after the letter "S". The specific classification and explanation of oil grades are as follows: 1. When letters exist alone: The "S" series represents oil for gasoline engines, with specifications including: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL. The "C" series represents oil for diesel engines, with specifications including: CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. 2. When both letters exist: When both "S" and "C" letters are present, it indicates that the oil is suitable for both gasoline and diesel engines. From "SA" up to "SL", each successive letter indicates that the oil's performance is superior to the previous one, with more additives included to protect the engine. The further the letter is in the alphabet, the higher the quality grade. Most international brands have oil grades above SF.

Can Engine Oils Be Mixed?

Automotive engine oils should not be mixed. Here is relevant information about engine oil: 1. Definition: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91kg×10³ and is hailed as the 'blood' of automobiles. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the deficiencies of the base oil, providing additional performance characteristics. Additives are an essential part of lubricating oil. 2. Function: Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber.
