Re: tire pressure
well yes true ,, but the machine only supplies 75% true nitrogen ,, nascar and the airlines use bottles that is produced at a chem plant that does oxygen and such ,, it is 100% nitro ,, and most tire shops don;t watch or have the stuff to get the moisture outta their air supply ,, cost to much ,, the air we breath has 45% nitrogen ,, so go figure ,, yes i do believe that it helps control moisture ,, but do one thing ,, ck u'r tires when they are cold ,, then drive say 100 miles ,, and ck them agian ,, and see what u get ,, i have done this ,, and u will be surprised at what the results are when u see them ,, but JMO
