------------------------------------------------ A tire has a recommended pressure of 32 psi. The TPMS should light the lamp when the pressure in this tire reaches:

A. 27 psi
B. 30 psi
C. 24 psi
D. 26 psi

Answer :

The TPMS should light the lamp when the pressure in this tire reaches: 30 psi.

Tire Pressure Monitoring Systems (TPMS) are designed to alert drivers when tire pressure falls below a certain threshold, which is typically a percentage below the recommended pressure. In this case, with a recommended pressure of 32 psi, a common threshold for TPMS activation is around 10% below that value.

Calculating 10% of 32 psi gives us 3.2 psi. Subtracting this from the recommended pressure (32 psi - 3.2 psi) results in 28.8 psi. Since TPMS systems may activate the warning light at slightly higher thresholds for practical purposes, it is reasonable to expect that the light would activate at 30 psi, as this is the closest option provided that is above the calculated threshold.
