Technician A says that tire inflation needs to be checked when the tire is cold. Technician B says that tire pressure can be checked as long as they have been driven less than 1 mile in the last 3 hours. Who is correct? a. Technician A b. Technician B c. Both Technician A and Technician B d. Neither Technician A nor Technician B

The correct answer is a. Technician A.<br /><br />Tire inflation should be checked when the tire is cold, meaning the vehicle has been stationary for at least 3 hours or has driven less than 1 mile. This is because the temperature of the tire affects the air pressure inside. When the tire is hot, the air inside expands and the pressure increases. Therefore, checking the tire pressure when it is cold gives an accurate reading.<br /><br />Technician B's statement is incorrect because tire pressure should be checked when the tire is cold, not based on the distance driven in the last 3 hours.
