How do cars detect low tire pressure?
How do cars detect low tire pressure?
Your vehicle’s direct TPMS uses a sensor located in the wheels. It measures the air pressure of each tire. If the pressure drops 25 percent below the recommended air pressure, the TPMS will be triggered and you will see the vehicle’s warning light on the dashboard.
How does a low tire pressure light work?
The TPMS (or Tire Pressure Monitoring System) uses sensors on the vehicle to determine when a tire has low pressure and alerts the driver with a warning light so the tires can be checked out.
What should I do if my tire pressure is low?
If a tire has low pressure, the dashboard TPMS light will illuminate. It may flash or stay on. If you see this while you’re driving, pull over as soon as it is safe to do so, and check the tire pressure on all wheels. Fill each tire to the pressure specified in the manual or the information panel on the inner door jamb.
What should the pressure be in a truck tire?
Pressure in a Truck Tire. According to the Society of Automotive Engineers the average pressure in a truck tire can range from 30 to 100 psi (pound-force per square inch) or 150 to 700 kPa (kilopascal). Pressure is defined by the formula P = F / A (force divide by area).
What should the tire pressure be on a low profile car?
A common factory specification is 32 psi. The maximum pressure rating of low profile (55, 60, 65% aspect ratio) tires is 44 psi. 32 psi gives a smooth ride on smooth to slightly bumpy roads. 35 psi improves fuel consumption and adhesion.

How does your car know your tire pressure?
Some vehicles have displays like the one above, which show a numeric tire-pressure reading for each tire. At minimum, a warning light showing that tire pressure is low will illuminate when that is the case.
What happens if your tire pressure is 5 psi?
You can also experience a loss of steering precision and cornering stability. While 5 psi doesn’t seem excessively low, remember, 5 psi is usually about 20% of the tire’s recommended pressure. An over inflated tire is stiff and the ride will be rough.
