Tire pressure standards, how to maintain car tires

Many car owners know that tire pressure is crucial for safe driving, but what is the standard tire pressure?
In fact, different car models, tires, climates, road conditions, and other practical situations have different requirements for tire pressure, so we cannot generalize.
So, how can we ensure that the tire pressure is within the standard range?
Prepare a pressure gauge. You can buy a better barometer from a car supplies store, the mechanical one, and the electronic one will have errors after a period of time. Anyway, a barometer can last for a long time. Step 2: Get up in the morning and measure the air pressure before starting the car (check once a month). Because the tire will completely cool down after being driven for 4 hours, the measured air pressure is most accurate at this time. Step 3: Check if there is a difference between the measured value and the standard value. The standard tire pressure is marked on the driver's side door or edge of the door (in addition, this standard value can also be found on the fuel tank cap and in the instruction manual). It should be noted that there are different standard units for representing air pressure, generally ranging from 3 to 4. Just like how weight can be expressed in kilograms or pounds, there are also 3-4 units of measurement on a barometer, such as kg/m2, bar, PSI, and kPa. The conversion relationship between them is as follows: 1bar=1.02kg/m2=102kPa=14.5PSI.
Baiye Auto Parts Network suggests that car owners do not need to worry about how to calculate this, just look at where the pointer on the barometer is pointing, what unit is used to indicate this position, and then see what the corresponding standard value of the vehicle's air pressure unit is. Check the difference between the measured value and the standard value. If it is too high, release some air, and if it is too low, replenish the air until the tire pressure matches the standard pressure. Note that if you find that the vehicle needs to be inflated, you can solve it on site with an inflator. If there is no owner, you need to go to the nearest tire shop to inflate it. The distance to the inflation point should not exceed 1.6km, as the tire pressure is still accurate within 1.6km after the car has been stationary for 4 hours. If it exceeds 1.6km, an additional 5% should be added during inflation.

The small tread area plays a big role, and the actual contact area between the tire and the road surface is only the size of a human palm. Your safety, comfort, and fuel economy all depend on this very small tread, because your tires: the connection point between the vehicle and the road surface, bear the entire weight of the vehicle - up to 50 times the tire's own weight, respond to driving actions such as steering, acceleration, and braking, and act on the road surface to absorb the impact of road obstacles.
Carefully inspect the tires you are using, including the spare tire, and check the tire pressure. Discover any bulges, cracks, cuts, spikes, and abnormal tread wear. Using damaged tires may result in tire damage. Driving a vehicle on roads with potholes, rocks, or other objects may damage the tires and cause poor vehicle positioning. Therefore, when driving on such roads, it is necessary to drive slowly and carefully, and after passing through these sections, check the tires for any damage, such as cuts, bulges, spikes, abnormal tire surface wear, etc.
wheel alignment
Correct four-wheel alignment helps ensure the normal handling of your vehicle and improves tire performance. Poor wheel alignment can also lead to irregular wear on the tire surface and shorten tire lifespan.
Tire adjustment
In order to achieve uniform wear of tires and extend their service life, tire alignment is necessary. Please refer to the guidance on tire adjustment in the vehicle manufacturer's user manual. For vehicles equipped with new symmetrical or asymmetrical tires of the same specification (regardless of front wheel drive, rear wheel drive, or four-wheel drive vehicles), tire adjustment is generally carried out every 8000-10000 kilometers of tire travel. However, if uneven wear is found on the tire surface (commonly on the driven wheel), it is necessary to perform front and rear wheel cross rotation as soon as possible. If the original tire specifications of the vehicle are different, adjustment between the front and rear axles is not allowed. Tire repair: Tires must be removed from the wheel rim and inspected by a professional tire dealer before deciding whether they can be repaired. The sidewall cannot be repaired, and holes with a diameter exceeding 6 millimeters that penetrate the tire crown cannot be repaired. If there is damage or deformation to the tire bead, tire surface, rubber corrosion by chemicals, or tire compression damage, other abnormal situations cannot be repaired Precautions for car tire maintenance: Tires are the only parts of a car that come into direct contact with the ground while driving.

The fact shows that many car accidents are caused by tire problems. With the expected implementation of the "Tire Industry Policy" within the year, tire recalls have also been put on the agenda, and tires have received increasing attention. So, as a car owner, what issues should we pay attention to in daily maintenance? If the tire pressure does not meet the standard and the driving danger is high, the vehicle should maintain the correct air pressure that meets the requirements when driving. This air pressure should refer to the information provided by the car manufacturer. Car owners should check the air pressure of all tires, including the spare tire, at least once a month when they are cool. If the air pressure decreases too quickly, the cause should be immediately identified. Be sure to check the air pressure before traveling long distances. UOHMB vehicles should not exceed the speed limit
It has been proven that the likelihood of tire injury from foreign objects during high-speed driving is much higher than during low-speed driving. Therefore, in any case, do not exceed the reasonable speed required by driving conditions and legal restrictions. If turning or encountering obstacles such as potholes ahead, slow down. When driving at high speeds, tires may collide with potholes and other external objects, causing severe compression deformation between the impact object and the wheel rim flange, which can cause the curtain fabric to break, and the air inside the tire will rise from the broken line to form bulges. Therefore, car owners must immediately replace the bulging tires. Do not continue to use damaged tires. Car owners should regularly check the condition of the tires for bulges, cracks, cuts, spikes, and abnormal tire wear, especially checking the edges of the tire tread to see if there is any abnormal wear caused by poor positioning or low-pressure driving. If this situation is found, the tire should be checked in a timely manner and the damaged tire should not be used again.  
Prohibit the use of over life tires with wear indicators at a depth of 1.6 millimeters left in the tread grooves. If the tire wears to this level, it must be replaced. It is dangerous to use tires that exceed the wear indicator, especially when driving in wetlands, as the drainage performance of the tires has greatly decreased with the wear of the tread pattern. When the vehicle shakes, be alert to whether it is a tire problem. When the owner feels that the vehicle shakes excessively, they should be alert to whether there is a problem with the tires, or if the tire positioning is poor, or if the tire wear is uneven, such as the shoulder of the tire wearing faster than the rest of the tire surface. When these situations occur with the tires, continuing to drive not only damages the tire life, but also affects the vehicle's handling and poses a danger. Adjusting the tire position once every 8000 kilometers is necessary to obtain the tire wear condition.  
The adjustment of tires should refer to the instructions on tire rotation in the user manual provided by the vehicle manufacturer. In the absence of clear guidance in the manual, car owners should generally adjust the tire position every 8000 to 10000 kilometers of driving. Tires should be stored indoors in a cool, dry, and dark environment to prevent moisture from accumulating inside the tires and causing danger. Due to pressurization, liquid may enter the tire body layer through the inner airtight layer of the tire, which may cause sudden damage to the tire.
