Just installed my winter tires that don’t have sensors. Last winter, the low pressure light came on however it’s been a day and still no warning light on the dash.

Will this light eventually come on or could the warning light be malfunctioning? Checking the dash screen still shows tire pressure amounts for each tire despite there being NO TPMS installed on my snows.

 

Give it a couple of days and the TPMS will not be able to detect the sensors and the dash light will come on and bother you for the rest of winter haha.
