    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Since the air we breathe hear on Mother Earth is 78% nitrogen, simply filling tires with "pure" nitrogen doesn't accomplish much.

The issue with compressed air is that the act of raising the pressure tends to increase the amount of moisture in the air. If the place that fills your tires has a good quality, well-maintained air dryer on the output of their compressor (and most big shops do), then the moisture isn't a problem because it's been removed from the air.

But, if filling your tires with "pure" nitrogen is a cover-up for the fact that they don't have dry air in available in the shop, then the nitrogen thing is worthwhile. In the end, though, I think the nitrogen thing has more to do with separating customers from their money than providing them with a real benefit.

Wow! I have a choice...

1) Keep a tank of compressed nitrogen in my garage. Check the pressure in the tires every two weeks. Fill as needed.

2) Check the pressure in the tires every two weeks. Fill, as needed, using the air compressor that I use for a dozen other things.
