my new Kia Niro can monitor tyre pressures the manual says). Sure enough recently an overhead image of a car appeared on my control panel showing flashing psi values against each wheel indicating 31/32 psi. They should be
36 psi all round.As soon as the snow cleared, I opened up my cigar-lighter-socket powered electric tyre pimp and went sound all four. it has an analogue gauge but the readings were all 36-38psi. I added a couple of bursts before unplugging.
The graphic still read 31/32 against each wheel.
I posted my bewilderment to a Kia Form and someone came back and said that was normal. The misinterpret when it is cold!
This is 2017, the age of powerful smart-phones. How come Kia cannot compensate for low temperatures?
Makes no sense.
