You can still drive with unstable tire pressure, but only if the air leakage is not rapid. It is advisable to drive a short distance and promptly check for issues such as punctures caused by nails. Tire pressure refers to the air pressure inside the tire. There is a label indicating the standard tire pressure on the inner side of the driver's door, which represents the pressure when the tire is cold—i.e., after the car has been parked for at least three hours or driven no more than 1.6 km. Unstable tire pressure poses safety hazards: 1. Increases the risk of a tire blowout; 2. Over-inflated tires reduce the contact area between the tire and the road, decreasing friction and extending braking distance; 3. Under-inflated tires increase the contact area with the road, raising friction and resistance, which also leads to higher fuel consumption; 4. Over-inflation causes excessive wear in the center of the tire tread, while under-inflation causes excessive wear on both sides of the tread, both of which can lead to premature tire failure.

I've been driving for over twenty years and have encountered unstable tire pressure several times. It's possible to drive a short distance to a repair shop or gas station to refill the air, but you must be extremely careful. Unstable tire pressure can cause the car to veer from side to side and reduce braking effectiveness, which is especially dangerous in rainy weather or on highways. I remember one night when I almost hit a guardrail—it was terrifying. Driving long distances with unstable tire pressure can damage the suspension or cause uneven tire wear, eventually leading to the costly need for new tires. Safety first—I recommend slowing down immediately, finding the nearest place to check and refill the tire pressure, and it's best to keep a tire pressure gauge in the car.

Why does the Envision shake at idle when the air conditioning is on?

The reasons for the Envision shaking at idle when the air conditioning is on are as follows: 1. Carbon buildup in the throttle body: Carbon deposits can obstruct the engine's air intake, causing the engine to struggle or barely manage to drive the compressor, resulting in idle shaking. 2. Large throttle angle: This can lead to excessive air intake, causing the engine to shake and lack power during acceleration when starting. 3. Issues with the ignition system: For example, poor spark plug performance can lead to unstable idle. Relevant information about car idle is as follows: 1. Car idle: Refers to an operating condition. When the engine is running without load, it is called idle, meaning the car is in neutral gear. The engine speed during idle is referred to as idle speed. 2. Adjustment: Idle speed can be adjusted by modifying the throttle opening size, among other methods, to increase or decrease it.

Why is the startup sound of BMW 1 Series so loud?

The phenomenon of a very loud startup sound in the BMW 1 Series occurs because, after the car has been parked for a long time, the engine oil slowly returns to the bottom of the oil pan. This results in insufficient lubrication in the upper part of the engine during startup, leading to the loud startup sound. Below is more information about the BMW 1 Series: 1. The BMW 1 Series is a model series from BMW, with the revamped version making its first appearance at the Geneva Motor Show in 2015. 2. The new BMW 1 Series integrates sporty elements into every detail of its design, inheriting the characteristics of BMW cars and perfectly showcasing the functionality of the hatchback model and BMW's typical driving performance. 3. The BMW 1 Series is a compact luxury car, equipped with five genuine leather seats. Its top speed varies depending on the powertrain configuration, reaching up to 213 km/h, demonstrating outstanding performance.
