I'm sure that it varies by dealership. My last Lexus (2010 model) came with nitrogen installed prior to delivery at no charge. they do it with all new car deliveries. I wouldn't pay to have nitrogen added but did see some benefit from it in terms of tire pressures remaining constant with temperature changes.

Anybody use nitrogen in their Lexus? Does Lexus dealership charge? If so, what?
Feedback please!

I don't know how much they charge, but I'm sure you could call and ask the service department. When I purchased my Lexus recently my sales person told me about the nitrogen and I asked him how do I go about refilling it with more nitrogen should I need to, and he told me that some Shell gas stations are outfitted with nitrogen refill stations (I'm sure at a cost). I haven't had the chance to investigate further.

I'm pretty **** about maintaining my tire pressures. I travel a lot at highway speed so I want the pressures to be dead on. In as much as regular compressed air is 78% nitrogen anyway and I have a nice air compressor I just maintain my own tire pressure. Not sure I'd want to pay for nitrogen and find I had to add or reduce the tire pressure and use regular air. Regular air loses or gains 1 PSI for every 10 degree temperature change. My temperature range can go from zero or below to100 degrees.
A nitrogen filled tire set at 30psi @ 100 F (310.92 K), would be down to 24.6 psi at 0 F (255.37 K).
conversely,
A nitrogen filled tire set to 30 psi @ 0 F (255.37 K), would be up to 36.5 psi at 100 F (310.92 K).
Third Gas Law
P1xT1 = P2 x T2
or P2 = (P1xT2)/T1
So even with nitrogen, I still will need to maintain my tire pressures and since I don't have a tank of nitrogen in my garage I will be mixing air and nitrogen anyway.

Apparently the costco tire centers use nitrogen. I was looking at someone's receipt for having a nail removed and patching the tire. There was a line item for nitrogen, for $0.

When are they going to enable cars to adjust their air pressure while you're drining it? Compressors are easy to incorporate. I'll bet there are some clever engineers that could figure that out. Then you could just enter the pressure you want. Maybe allow a range of pressures according to outside temp & driving conditions
