tire pressure is correct but the flat tire symbol stays on

It is important to have a properly functioning TPMS so you can be alerted if your tire pressure falls outside of the correct range. If this is the case, it may be safe to drive on them, but you should fix the issue as soon as possible or contact a tire service professional. If you check the pressure of your tires (including your spare if it has a TPMS sensor) when they are cold (it’s been three or more hours since they were driven on) and they are all at the recommended PSI, this may mean your TPMS is not functioning properly. The TPMS exists for safety reasons, so when it indicates a problem, you should heed it and check your tires’ pressure. If this doesn’t work, check your vehicle’s manual for instructions on how to reset the TPMS system, or consult a tire professional. Stop the car, turn it off, and when you start it up again the TPMS should be reset and the light off. If you have aired up your tires to the correct pressure but the TPMS is still on, try driving your car at 50 miles per hour for around 10 minutes. That pressure value varies from vehicle to vehicle and is listed in the car manual or on a sticker on the driver’s door post.

law, the TPMS is required to warn the driver of cars and light trucks when tire pressure is 25 percent above or below the recommended pressure for that vehicle. At what pressure does TPMS light come on?
