The max pressure for the tire will be listed on the sidewall.
The recommended pressure for the vehicle will be listed on a sticker on the driver's door jamb.
fill the tires with air to the proper pressure.
About 8 PSI
I have 245/70R16 tires on a Honda Passport SUV. What is the proper air pressure for the tires?
33 psi
fill tires with proper air pressure, if the light remains on after a short drive you probably have a failed tire pressure sensor. Replacement of sensor necessary.
Check the label on the driver's door jamb for proper air pressure. Do not use what is printed on the side of the tire. That is the max safe pressure for the tire, not the recommended pressure for the vehicle.
If sensor is good will reset itself if proper air pressure in a few miles
No, you don't have to. Air is air, no such thing as summer or winter air just check and maintain the proper air pressure required for your vehicle.
Cupping is caused by lack of regular tire rotation and proper air pressure. Check the owner's/service manual for frequency of tire rotation and correct air pressure for your vehicle.
Air Pressure
The MAP sensor ( Manifold Absolute Pressure sensor) sends the correct internal pressure to the ECU for the proper fuel/air mixture.
Maintain proper air pressure in tires.
