As of 2007, thanks to Congress, all vehicles must have tire inflation monitoring systems, which usually consist of a sensor and radio transmitter in each wheel. The trend now is to fill these tires with nitrogen, a practice long used in aviation (I’m a licensed pilot and aircraft mechanic). Nitrogen is dry (no water) and is less susceptible to pressure variations due to temperature, which often causes the stupid tire light on the dash to come on and freak out people. Over-inflating is very dangerous for the reasons you’ve already heard. The issue on tune-ups was handled yesterday on Rush’s show. HTH
Very interesting.
But where is the closest Nitrogen store so I can postpone drilling in ANWAR?
