In summer, it is generally sufficient to maintain the tire pressure at the lower limit of the standard range. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can usually be about 0.1 bar lower than the standard to avoid blowouts due to high temperatures. Hazards of excessive tire pressure: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the car while driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts.

When it comes to tire pressure in summer driving, I usually refer to the vehicle manual or the label on the door frame, which indicates the recommended value, typically around 32 to 35 psi or 2.2 to 2.4 bar. In summer, high temperatures can cause tire pressure to rise due to thermal expansion, and excessive pressure increases the risk of a blowout, affecting handling and fuel consumption. I always check with a portable tire pressure gauge during seasonal changes, especially when the car is cold in the morning, to ensure it stays within the recommended range. I remember once after driving in high temperatures, the tire pressure reading was slightly higher, but I didn’t adjust it because the manual stated that maintaining the original value is fine, as long as I check it monthly. It’s also important to monitor tire wear, as summer accelerates deterioration, and regular checks can enhance overall driving safety.

What is the process of buying a car in full payment?

Here is a detailed introduction to the process of buying a car in full payment: 1. Sign the contract and pay the deposit: After selecting the appropriate model based on your car usage, preferences, and budget, you can sign the contract with the 4S store. 2. Pick up and inspect the car: Once the car arrives at the store, the salesperson will contact the owner to pick it up. The new car will come with a PDI inspection checklist. Check each item on the list carefully, paying special attention to whether the paint has any scratches. You can also request to have the car lifted in the workshop to inspect the chassis. 3. License plate registration and insurance: To legally drive the car on the road, you need to pay the purchase tax, vehicle and vessel tax, and also handle car insurance. Only after these are completed can you proceed with the license plate registration. After obtaining the temporary moving permit, you can drive the car to the vehicle management office for inspection. During the inspection process, you can choose the license plate number. Wait for the metal plate and vehicle license to be made, and for the new car to pass the inspection. Once the license plate is installed, the car is legally ready for the road. 4. Install accessories: The accessories you choose to install or receive as gifts when buying the car are usually added after the inspection, such as window tinting, installing a roof rack, mudguards, changing the headlights, or installing a reversing radar, etc.

What Causes the Engine to Stall at Idle?

Possible causes include clogged idle air jets, malfunctioning idle control system, weak spark in individual spark plugs, poor valve sealing, intake manifold leaks, incorrect ignition timing (either too advanced or too retarded), and improper idle speed adjustment. Engine Idle Instability: When experiencing unstable engine idle, first adjust the idle speed. If the issue persists after adjustment, inspect whether the idle jets and idle air jets are clogged. Checking for Air Leaks: If the jets are not clogged, stabilize the engine at a constant RPM and listen for air leaks at the intake manifold or the lower gasket area of the carburetor. Inspecting Spark Plug Performance: If idle instability is accompanied by reduced engine power, further examine spark plug conditions, valve sealing performance, and whether the ignition timing is correctly set.

What is the standard air pressure for spray painting?

Spray painting normally requires an air pressure of 0.3~0.6Mpa. Air pressure spray painting: Air pressure spraying is a method of coating where compressed air is used to atomize the paint and spray it from a nozzle onto the substrate (plastic or other materials) surface. Introduction to spray painting: Spray paint is a type of synthetic paint made from nitrocellulose, resins, pigments, solvents, etc. It is typically applied evenly on the surface of objects using a spray gun, is water-resistant, oil-resistant, dries quickly, and is used for painting cars, airplanes, wood, leather, etc. This substance is toxic and can have certain effects on the body. Different brands of spray paint vary in toxicity due to differences in composition and content. Special attention should be paid to safety during use to avoid inhalation and skin contact.

How to Black Out Chrome on a Car?

While toothpaste shows noticeable effects, it's helpless against stubborn scattered rust spots. Toilet cleaner is included in the selected materials because it's frequently mentioned in Autohome forum discussions related to rust removal. WD-40 rust inhibitor was found during online searches for anti-rust products. According to product information, it has strong surface affinity and permeability for metals. Carburetor cleaner is almost a universal cleaning product in the automotive repair industry, capable of removing stubborn stains like oil marks and adhesive residues. Brass polishing paste, similar to WD-40 rust inhibitor in sourcing, demonstrates excellent rust removal effects on most metal materials.

What is the difference between mobile phone connectivity and CarPlay?

The differences between mobile phone connectivity and CarPlay are as follows: Supported phones are different: If the car has original factory connectivity mapping, it can support different mobile phone brands; the CarPlay system can only connect with Apple iPhones. The apps used are different: Original factory connectivity mapping requires downloading the manufacturer's app software to achieve connectivity between the phone and the car's system; when connecting a phone to CarPlay, the CarPlay app needs to be downloaded for connectivity. The installed functions are different: Original factory connectivity mapping can only use the app functions provided by the manufacturer; whereas CarPlay allows the use of most functions of the phone on the car's system.

Is it easier to pass the driving test in rainy weather?

During the driving test in rainy weather, visibility is poor, making it more difficult to pass. Here are some precautions for taking the driving test in the rain: 1. Stop if visibility is unclear: Poor visibility is the biggest hazard when driving in heavy rain. Even with the wipers on high speed, the rain on the windshield cannot be completely cleared, making it difficult for the driver to see ahead. In such cases, it's best to pull over to the side of the road and wait, while turning on the hazard lights. 2. Driving through waterlogged areas: When passing through waterlogged sections, observe the driving conditions of other vehicles to avoid obstacles like deep potholes. If the water level submerges the exhaust pipe, be cautious of water entering it. To prevent this, shift to a low gear before entering the water and maintain a steady, higher speed to drive straight through. After driving through waterlogged areas or heavy rain, the brake pads may become wet, reducing braking efficiency or even causing brake failure. To address this, drive at a low speed while lightly pressing both the accelerator and brake pedals to heat the brake pads and evaporate the moisture. 3. Navigating muddy sections: When driving on muddy roads, focus on preventing skidding and getting stuck. Always follow the tracks of the vehicle ahead. Shift to a low gear before entering the muddy section and avoid changing gears midway. 4. Brake earlier in the rain: The braking distance on wet roads can be up to three times longer than on dry roads. Therefore, brakes are less responsive in rainy weather. For safety, apply the brakes earlier than usual.
