Question

Technician A says that a tire will increase or decrease approximately 1 psi for each 10°F change of temperature. Technician B says that if the vehicle has been driven to warm the tires, you must adjust the air pressure down to the manufacturer's recommended pressure. Who is correct?
A. Tech A
B. Tech B
C. Both Techs A and B
D. Neither Tech A nor B

Answer 1

Answer:

Technician A

Explanation:

It is seen that a tire pressure will increase or decrease 1 psi for each $10^{\circ} F$  change in temperature.

For Technician B vehicle pressure should not be adjusted after tire has been warmed as the warm air may increase the pressure but it will be auto adjusted as  the temperature falls to normal .
