The Tire Pressure Indicator invariably shows that I need air in one of the tires,
yet when I check out all the tires they seem OK. I did have a new tire replaced about a month ago. I did re calibrate the tires after every time indicator went to off. But invariable comes back on after a day, or 2 weeks.

Has anyone had this situation, and how was it corrected?

Thanks,

Ralph

 

Spare tire low.
