Hello. I may possibly be purchasing a 2005 Altima 3.5SL. The dealers website offered the free Carfax report which I reviewed. I noticed that one of the things the previous owner did was fill the tires with nitrogen. I have heard of this before but cannot remember any specifics.
1) Is it true that you can go longer between inflations (I use good old fashioned air in my current car once a month).
2) Is it true that once you go nitrogen you cannot switch back to air (or you can but it's complicated)?
3) What are the pros and cons of nitrogen inflations vs air inflations? (I know that the price is the main thing. Air is free at the local tire shop. Also, I have seen coupons for nitrogen inflations for $19.99 which lets me know the regular price is more expensive. I mean, even if the inflations last longer, that's still expensive in my opinion).
Let me know your thoughts. Thanks.
