Atleast 10 km in city drive and 30 km in highway drive.
Depends on the vehicle and tire size. -Check at your tire store, this is not something you should guess.
At least once a week.
Perhaps you should try checking your tire pressure and reinflating them to the recommended pressure.
I check mine every other day, and keep a good tire gauge in each car.
You should check the air pressure at least once a month.You should check the air pressure at least once a month.
Check the inside of the front drivers door frame the tire pressure should be on a sticker there
check the driver door, driver door frame, or inside the gas fill cap for a label telling you what your tire pressure should be.
there should be a sticker on the door jam of your car (if not check the manual) of what the manufacturer recommended tire pressure.
Check the label on the drivers door jamb. That has the recommended pressure.
You should not reduce tire pressure just because you are going to be on a long roadway. You should set the pressure to the cold pressure as specified by the vehicle and tire manufacturers and you should leave it alone. It is normal for the pressure to increase when the tire is hot. DO NOT bleed it off. This will cause the tire to overheat and potentially cause it to fail, possibly with catastrophic consequences. Alwaysadjust pressure when the tire is cold.
The tire sidewall will list the max pressure. Check the owners manual or the driver door jamb sticker for the correct pressure for the vehicle
Yes. The light means that one of the tires is not reading correctly. Either from improper pressure or a sensor problem.
