Now I traded for a 2012 RX350 with oxygen in the tires which brings up my question:
Is there less water in nitrogen that will reduce or slow down oxidizing on my new rims over time??
Wow; someone sold you something....common sense should tell you that if ANYONE had trouble with aluminum rims oxidizing at Lexus, there would be a problem.
Compressed air has water in it ONLY if the tire shop does not have a good WATER filter!
Nitrogen is a complete waste of money; only good for dealing with HEAT, and we don't have enough to matter!! Saw a dealer in Arizona was charging $99 for nitrogen......so much ignorance in the world........BE careful; it could be flat and we may fall off!!!
Edit.......JM Lexus In Florida, the largest dealer in the US, is offering FREE LIFETIME NITROGEN!!!!!, How do they do it????? About 5 Cents per tire ...........llolol
