What is the general tire pressure for car tires?

1 Answers

Typically, the inflation pressure for household car tires is between 0.2~0.25MPa. The hazards of either too high or too low tire pressure are as follows: Hazards of too low tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption. The friction between the tire and the ground multiplies, causing the tire temperature to rise sharply, the tire to soften, and its strength to drop drastically. When driving at high speeds, this may result in a tire blowout. Hazards of too high tire pressure: The friction and adhesion of the tire decrease, affecting braking performance. It may cause the steering wheel to shake or veer, reducing driving comfort. It accelerates the wear of the tread pattern in the center of the tire, making it prone to bulging or trapping stones. Additionally, it causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body. This increases the impact experienced while driving and raises the noise level during travel.

How to Tell If Your Car Is Out of Gas?

To check if your car has gas, simply look at the fuel gauge on the dashboard. 'F' stands for full, and 'E' stands for empty. Here are some fueling tips: 1. When the fuel tank is down to a quarter full, it's time to refuel. Don't wait until it's completely empty. 2. Avoid overfilling the tank; leave some space. 3. Do not mix different types of fuel. Never add diesel or kerosene to gasoline. 4. Follow the gasoline standard specified on the fuel cap. There's no need to use a higher octane rating than required. 5. Always refuel at large or medium-sized gas stations. Avoid small, private ones. Using low-quality, sulfur-containing gasoline can poison the oxygen sensor and cause a series of troublesome issues.

Where is the Peugeot 408 fuse box located?

Peugeot 408 fuse box is located in the engine compartment. Here are the specific details about the fuse box: 1. Function: The fuse box is an overcurrent protection switch, mainly used to control circuit operation. There are many circuits in a car, and fuses serve to protect these circuits. When the circuit temperature is too high or the current is too large, the fuse will blow to protect the circuit. 2. Impact of Blowing: The car fuse box contains many fuses and relays. When a fuse blows, certain functions of the car will be affected. After a fuse blows, it needs to be replaced with a new one. 3. Replacement Precautions: When replacing a fuse, use a special clip to remove the fuse. The fuse box in the engine compartment is usually located near the battery, while the fuse box in the cabin is generally located in the main driver's position or the glove compartment on the passenger side.

What to Do When a Vehicle Has a Tire Blowout at High Speed?

Do not panic in the event of a tire blowout. Keep both hands firmly on the steering wheel and try to maintain control of the vehicle. Avoid stepping on the brake pedal and try to keep the vehicle moving straight. Once the car has come to a stop, contact roadside assistance as soon as possible. Here are additional solutions for dealing with a tire blowout while driving: 1. When a tire blows out, the front of the car will veer due to inertia. At this point, firmly grip the steering wheel to mitigate the loss of control. Be careful not to attempt to jerk the steering wheel, as the strong inertia could easily cause the car to roll over, leading to severe consequences. 2. Lightly applying the brakes can also help mitigate the situation, but avoid slamming on the brakes, as this could have the opposite effect, causing the vehicle to become even more uncontrollable. Additionally, set up warning signs.

What is a Cold Running-in Engine?

Cold running-in engine refers to mounting the engine on a dedicated machine tool and then using an electric motor to drive it for running-in. Since there is no heating from fuel combustion as in normal engine operation, this type of running-in is called cold running-in. Better methods for engine cold running-in are as follows: 1. Warm up before starting. For fuel-injected vehicles, turn the key to the second position and wait 5-10 seconds before starting. 2. Avoid high-speed driving. Control your speed during the initial running-in phase and try not to drive at high speeds. 3. Try to avoid excessive load during the cold engine phase. 4. Avoid emergency braking as much as possible, as it accelerates wear. 5. Do not remove the speed limiter prematurely. 6. Try to avoid long-distance trips.
