What Does the Car Tire Model Number Mean?

Car tire model numbers have the following meanings: Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire section width, and the latter represents the rim diameter, measured in inches. Below is relevant information about car tires: 1. Definition of Tires: Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help cushion the impacts encountered during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capabilities. 2. Effects of Low Tire Pressure: Tire pressure is crucial to tire longevity—both excessively high and low pressures can shorten its lifespan. Low pressure increases tire body deformation, leading to cracks on the tire sidewalls and causing flexing movements that generate excessive heat. This accelerates rubber aging, fatigue in the cord layers, and breakage of the cords. Additionally, low pressure increases the tire's contact area with the ground, accelerating wear on the tire shoulders. 3. Effects of High Tire Pressure: Excessive tire pressure causes the tire cords to stretch excessively, reducing the tire body's elasticity. This increases the load on the vehicle while driving, potentially leading to internal cracks or blowouts upon impact. High pressure also accelerates tread wear and reduces the tire's resistance to punctures.

What causes the idle vibration of the Trumpchi GS4?

The reasons for the body vibration of the Trumpchi GS4 at idle: 1. Severe engine carbon deposits. The most common cause of car vibration is a dirty throttle or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. The engine's combustible mixture alternates between being too lean and too rich, causing idle vibration after a cold start. 2. Ignition system issues. Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or weak spark plug firing can also lead to such faults. 3. Unstable fuel pressure. If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can cause body vibration. The solution is to check the fuel pressure and replace components if necessary. 4. Aging engine components. Engine mounts are essentially the shock absorption system of the engine. They absorb minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the cabin, causing vibration at idle.

Does a brake pad thickness of 4mm require replacement?

If the brake pad thickness is less than 5 millimeters, it needs to be replaced promptly. Here is relevant information about brake pads: 1. Introduction: Brake pads consist of a friction material layer, heat insulation layer, adhesive layer, and backplate. The brake pads work by the brake caliper pushing the backplate to press the friction material against the brake disc for braking, making the quality of the friction material particularly important. 2. Precautions: Emergency braking causes significant damage to brake pads. Therefore, it is advisable to brake gently or use intermittent braking during normal driving to minimize wear on the brake pads.

What is the correct way to depress the clutch when driving?

The correct way to depress the clutch when driving is: 1. Adopt the proper posture - place the ball of your foot on the clutch pedal with your heel touching the ground, keeping your knee slightly bent when fully depressing the clutch; 2. Avoid using only your toes or lifting your heel off the ground to prevent insufficient force or slipping; 3. Always depress the clutch fully and avoid prolonged partial engagement to ensure complete separation and prevent wear. The functions of the clutch are: 1. Gradually increase driving force for smooth vehicle starting; 2. Temporarily disconnect the engine from the transmission for gear shifting; 3. Protect the transmission system from overload; 4. Reduce torsional vibration impacts from the engine and extend transmission gear lifespan.
