My Kia forte tire pressure warning sign was realised, I went to check it and the tire were 35 psi. I inflated to 40 psi and the warning sign is still on. What should I do?
First of all put the pressure at what the plaque on the drivers door jam lists . Then look at your manual and see if the spare is monitored by the Tire pressure system. If that does not work then a tire shop can use a tool to reset the monitors unless one has failed.
