What is the appropriate tire pressure for a Corolla?
1 Answers
The recommended tire pressure in the Corolla user manual is 2.3~2.5 bar, which is acceptable as long as it falls within this standard range. However, during summer when temperatures are high, the tire pressure, originally within the normal range, may actually rise above 2.8 bar after driving. Therefore, in summer, it is advisable to maintain a slightly lower tire pressure within the normal range, with 2.0~2.3 BAR being more appropriate. The methods for tire pressure monitoring are as follows: 1. Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. 2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the pressure in a tire decreases, the vehicle's weight will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the purpose of monitoring tire pressure is achieved. 3. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared to using only a direct system, this composite system can reduce costs and overcome the drawback of indirect systems being unable to detect low pressure in multiple tires simultaneously.
