Hoping some of the more knowledgeable car folks can help diagnose a recurring issue I'm having with my car. My rear passenger tire consistently loses pressure, every 10-14 days the low pressure light comes on. It is always the rear passenger tire, all other tires are fine. At first I thought it was the tire, but had them looked at and no leaks found. Then I had the tires rotated, and the rear passenger tire still consistently loses pressure. Wondering if this could be an issue with the wheel itself? Car is coming up on its warranty so obviously I plan on letting the dealer know before it goes over, but any points in the right direction are appreciated!
