I hit a hidden huge pothole several weeks back. Now I think I have a small leak in my passanger side rear tire because the TPMS keeps telling me I have a flat tire. Is this something that might be covered warranty wise or even AAA? I have about 1200 miles on the MO, and it will be a year old in March. I have filled the tire probably every other week so I know that it wasn't just because of the colder weather we have had lately. If I have to "bite the bullet" and buy a new tire should I actually buy 2 to balance out the old/new tire ratio? Thanks for any input.
