Why Is the Tire Pressure Sufficient but the Tire Still Looks Flat?

Tire pressure being sufficient but the tire still appearing flat is a normal phenomenon, as most tires currently in use are tubeless tires with a typical pressure range of 2.2-2.6 bar. Below is an introduction to the normal range of tire pressure and the effects of low tire pressure: Normal Range of Tire Pressure: The normal tire pressure for a car is between 2.3 and 2.5 bar. The standard pressure can usually be found on the label near the driver's door (B-pillar), in the drawer next to the driver's seat, or in the vehicle manual located on the fuel tank cap. Effects of Low Tire Pressure: Low tire pressure can lead to increased fuel consumption, heavier steering, and a tendency for the vehicle to pull to one side. It can also cause damage and abnormal wear to the tire bead area, reduce tire strength, and even lead to a blowout during high-speed driving.

I've encountered this situation before. When I checked with a tire pressure gauge, the pressure was actually within the standard range, but visually the outer side of the tire appeared noticeably deflated, as if it lacked air. This is likely an optical illusion because many new car models now come with low-profile tires, which have smaller sidewall heights and wider treads. This design is intended to improve handling stability, but it can make the tires appear flatter when stationary. Additionally, if you measured the pressure when the tires were cold, the temperature rise after driving may cause the tires to expand and change their appearance, though the pressure remains adequate. I've also noticed that if the car is parked on a slope or the wheels aren't aligned straight, one side of the tire may appear more deflated. For safety, I recommend regularly checking the tire pressure with an accurate digital gauge, preferably when the tires are cold. Don't rely solely on visual judgment—if there's an actual leak, ignoring it for a long time could lead to uneven tire wear or even a blowout, compromising driving safety.

Why is the new Santana heavy?

The reason for the new Santana's heaviness is due to a heavy clutch. Reasons for a heavy clutch: A rusty or worn clutch cable can cause a heavy clutch, a rusty or worn clutch pedal can cause a heavy clutch, and a damaged clutch pressure plate can cause a heavy clutch. Clutch maintenance: Before installation, the clutch must be thoroughly cleaned to remove anti-rust grease and debris. The clutch can be installed coaxially or on separate shafts, but axial fixation is mandatory. Neither the driving nor the driven parts should have axial play. When installed on separate shafts, the coaxiality between the driving and driven parts should not exceed 0.1 mm. For wet electromagnetic clutches, lubricating oil must be added between the friction plates during operation.

Why is the cooling fan noise loud when the car air conditioner is turned on?

The reasons for the loud noise from the cooling fan when the car air conditioner is turned on are as follows: 1. The fan blades inside the air conditioner are deformed and should be replaced. 2. The motor of the fan inside the air conditioner is damaged and should be replaced or repaired. 3. There is excessive dirt inside the air conditioner, and it is recommended to clean the air conditioner. Additional information: The car air conditioning system, abbreviated as car AC, generally includes a refrigeration device, heating device, and ventilation device. This combined system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.

How to install the timing chain on Roewe 350?

Roewe 350 timing chain installation method is as follows: 1. There is a small hole blocked by a white plastic plug near the lower right of the engine transmission exhaust manifold. 2. Remove the plug and insert an L-shaped iron rod of similar size to the hole, which should just pass through a hole on the flywheel (this appears when the four pistons are parallel). 3. Remove the transmission, and there is a hole on each camshaft (between cylinders 2 and 3). 4. After aligning the hole on the flywheel with the hole on the engine, ensure the two holes are vertical. 5. Insert parallel into the two holes on the camshaft to ensure the camshaft holes are relatively upward and parallel. 6. Then tighten the two previously loosened cam gears. Before this, pre-tighten the chain and the large pulley.

What to Do When You Lose Your Car Keys?

Solutions for lost car keys are as follows: 1. It is necessary to replace all car locks to prevent vehicle theft. After setting the lost key as an illegal key at a repair station, although this key cannot start the vehicle, it can still open the car door, posing a risk of theft of valuable items. 2. If there is no spare key, you need to go to a repair station or 4S shop to match the key. You will need to provide the vehicle registration certificate, the owner's ID card, the 17-digit key anti-theft password, and the metal key tooth shape number. 3. In daily life, you should take precautions to prevent the loss of car keys. Keep the spare key separate from the main key and do not lock the spare key inside the car. If the car does not have an anti-theft system, you can install an anti-theft system on the steering wheel to prevent car theft after losing the car keys.

What is the emission standard for cars produced in 2013?

Most models produced after March 2013 comply with the China IV emission standard, while some imported models meet the China V emission standard. Relevant details are as follows: 1. Starting from July 1, 2013, 19 regions including Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Urumqi, and Lanzhou strictly implemented the China IV standard. The China IV emission standard was fully implemented nationwide from January 1, 2014. 2. You can determine a vehicle's emission standard through the following five methods: (1) The simplest and most direct way is to check the vehicle's environmental protection label, which clearly indicates the standard on the back. (2) Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. (3) Bring the vehicle registration certificate (original or copy) to the local vehicle management office for inquiry. (4) For new vehicles, you can check the vehicle's conformity certificate. However, the certificate is usually kept by the vehicle management office. Therefore, it is recommended to make a copy when purchasing a new car for future reference. (5) Make a rough estimation based on the year the vehicle was registered.
