Which of the following can lead to incorrect or variable tire pressure readings? a) Sudden temperature changes due to the weather b) Having the vehicle doors open or closed (1) Low coolant levels d) None of the Above

The correct answer is a) Sudden temperature changes due to the weather.<br /><br />Sudden temperature changes can cause the air inside the tires to expand or contract, leading to incorrect or variable tire pressure readings. This can happen when the vehicle is exposed to extreme heat or cold conditions, such as during winter or summer months.<br /><br />Having the vehicle doors open or closed (option b) may affect the tire pressure slightly, but it is not a significant factor that can lead to incorrect or variable readings.<br /><br />Low coolant levels (option d) are not directly related to tire pressure readings. Coolant levels in the engine are separate from the air pressure in the tires.<br /><br />Therefore) Sudden temperature changes due to the weather.
