I hit a pothole yesterday and my 2011 Nissan Sentra began to wobble. I realized my tire was effected and was losing air. I'm unsure of the size of my tires but I inserted fix-a-flat (for tires of 14") and not much happened. I drove to the gas station to insert air and my tire filled up 3/4 the way. I drove about 8 miles heading home when I decided to stop and fill my tire with air the rest of the way. How long will the fix-a-flat maintain the air level in my tires? It's cold now here in Michigan so will that prolong the air hold in my tire? Must I change the tire or how will I know if I need to purchase or repair my tire? If I have all-weather tires is there a greater possibility that the fix-a-flat permanently fixed the issue? I need on help determining the best yet low cost next step.
Fix-a-flat is a very temporary fix, not a long-term repair. The cold temperatures will not help the tire loosing air. Your best bet is to take it to a shop and get the tire repair or replaced as necessary. Make sure you tell the shop upfront that the tire has fix-a-flat in it. While the car is in the shop, have them take a quick peak and make sure the tire was the only item damaged.

You may have a couple of problems here. Number one it sounds like you may have damaged the rim when it hit the pot hole and the tire. Fix a flat was designed as a very temporary fix to get you somewhere the tire could be repaired or replaced. Number two fix a flat many times will damage the TPM sensor that is mounted inside your tire. Take the car to your local independent tire dealer and have it checked out and the fix a flat removed from the tire. They will need to check the rim and tire for damage and remove and inspect the TPM sensor if it is damaged it will need to be replaced so the system will operate properly.
