Introducing water is another thing. Even if you have regular air in your tires you should avoid poor quality air (moist). I've seen gas stations that had water dripping out of the air hose.  |
This is indeed a common problem. Probably best thing to do is either get a good 12v air compressor (I've never seen one that actually worked) or a tank of compressed air to use when adding air to the tires. I always used regular air until i got my last, now retired Mercedes with free nitrogen fill from the dealer. Never had to adjust air pressure in any of the tires in two years I owned the car, even when I drove up to very cold northern Michigan. But since I've never had rft's before (will find out in two weeks when I get my new X6), people (thank you Midwest for your help) with much more experience with rft's than I have suggested that the nitrogen is totally unnecessary for street use.
