Tires: Slow leaks from tires, jeep grand cherokee, slow leaks

Question
I have a 2011 Jeep Grand Cherokee. Every fourth day I have to add air in the two back tires. I can't find anything on or in the tread. What I did notice is a small piece of  plastic wrap between the tire and rim. Maybe the covering from the wheel. Can this little piece of plastic  be causeing the air leak? Thank you for any help.

Answer
Randy,

That is possible.  You need to spend some time looking for the leakage.  Some folks use a spray bottle with detergent looking for bubbles.  The bubbles will be small because the leak is slow.

Another way to do this is to submerge the tire and wheel.  Some folks use a kiddie pool for this purpose.  Again, the leak is slow so the bubbles will be small and hard to detect.

Good Luck.
