Can someone tell me if your TPMS light will come on if you have too much air in your tires? I know it will come on if you lose pressure or are low on air but what if you put too much air in?

 

It will not turn on if you have to much pressure

 

I don't know for a fact if they do on Hyundai's, but they do on Nissan's, so it's possible. Don't you have an owner's manual. That's the kind of info you'd find in there. Go ahead... It's ok to take the plastic wrap off it.
