What is the normal range of tire pressure for sedans?
1 Answers
The tire pressure value for sedan tires is between 2.3 and 2.5. An increase in tire temperature will lead to an increase in internal tire pressure. The specific details are as follows: Methods for checking car tire pressure: Ensure the tires are "cold." This means the car has not been driven for more than 2 kilometers. Checking the pressure of cold tires ensures that the air inside has not expanded due to heat, making the pressure reading more accurate. Unscrew the cap of the tire valve stem. The valve stem is a black, pencil-sized extension near the wheel hub cover, approximately 2 to 3 centimeters long. Press the tire pressure gauge evenly onto the valve stem and record the reading on the gauge. If a hissing sound is heard, it indicates the gauge is not pressed tightly or evenly enough to obtain an accurate reading. Replace the valve stem cap. The cap does not keep air in the tire permanently, but it prevents dirt and moisture from entering the valve mechanism, which maintains the air inside the tire. Hazards of overinflated or underinflated tires: When tires are underinflated, the potential risks are even greater than when they are overinflated. Underinflation causes the tire sidewalls to become too soft, leading to dangerous heat buildup and eventually causing the tire casing to rupture. Underinflation also affects tire lifespan; when pressure is 30% below the standard, tire life can be reduced by up to 52%.
