#17 of 18 Need my Nitrogen Tires Filled by dago55 Aug 11, 2009 (6:00 pm)
I have been chasing the dealership I purchased my Nissan Versa from about getting my tires filled; since unbeknown to me the tires are filled with nitrogen. Each time I have called the dealership; plus stopped in they tell me the machine is broke. I check with Discount and Big O and they don't carry nitrogen. I live in AZ and my tire light is on and my tires are low...Can you add air to the nitrogen tires without damage. Any ideas, I am getting very ticked off...

Replying to: dago55 (Aug 11, 2009 6:00 pm) You can add regular air to nitrogen filled tires. It will just dilute the nitrogen a very small percentage. Normal air is about 80% nitrogen and 20% oxygen. So by putting air witht the nitrogen you would have just a couple of % oxygen versus about 100 nitrogen. Over time, and without additional nitrogen you would get closer to a regular air mixture. I have had very good luck in Chicago area with two vehicles with nitrogen(nothing added for almost a year in both vehicles). Maybe the high temperature of AZ affect the nitrogen more. I wouldn't know about that but it is certainly ok to add regular air.
