Hi everyone I’m in the UK with a Yaris. I used to set the tyre pressure slightly higher. The temperature dropped recently so the tyre pressure warning light was on but my rear tyre pressure was 29psi which is just the exact number of what’s recommended on the door frame.
This is my first car so I’m not sure if that’s normal? Does everyone set their tyre pressure the same as the label? Has anyone had this problem of having the warning light on even when their tyre pressure is within the range?
Sudden cold weather can contract the air in the tire. This lowers the pressure and can sometimes make TPMS think there is a slow leak. Hopefully, it should go away if you drive normally and the tire warms up.
