"People would be far ahead to use regular air and check their tires more often than to adopt the whole nitrogen fashion statement."

On the above, we agree.

I just stopped by my local lexus dealership before i actually did a search cause i was picking up touch up, and asked about the nitrogen in the tires. They have the service which cost $100 for the fill up, that also gives you a membership to a roadside club which possibly replaces your tire in a blowout and etc. Something to look into.

For those contemplating and/or maintaining nitrogen in tires, you may wish to consider the following information found within Lexus Tech Tip L-TT-0068-11 [2013-07-02]: "Best Practice For Tire Rotation & Nitrogen Filling Procedures."

Regarding nitrogen filling, it states "Some customers may complain about vehicle vibration due to incorrect tire balance following a nitrogen refill. It has been found that nitrogen replacement may cause tire out-of-balance conditions if the tire is deflated and refilled with weight on the tire. When the original air in a tire is evacuated during the replacement procedure, the internal pressure against the tire carcass is reduced. If the vehicle is on-the-ground during this procedure, the low tire inflation pressures may cause the tire sidewall to compress. When performing nitrogen replacement procedure with the tire/wheel on the vehicle, ensure the vehicle is lifted on a rack or jack stands. This prevents the weight of the vehicle from compressing the tire sidewall when tire pressure is reduced. Alternatively, the nitrogen replacement procedure may also be performed with the wheel/tire removed from the vehicle and suspended off-the-ground; for example, on a wheel/tire balancer machine."

Interesting ☝......never thought about balancing issues when you fill with nitrogen while the car is on the ground

I don't think it's actually balance, it sounds like permanent deformation of, or damage to, the sidewall changing the shape of the tire and affecting balance. IMHO, you'd be foolish to remove all the air from the tires with the weight of the car on the wheels, and if you're doing it right, you're actually pulling some vacuum so the tire has less than atmospheric pressure in it when you refill with nitrogen. Tires are not engineered to support the load of the car without air as anyone driving on a non-RFT without air knows. I bet you could do this with RFTs though.
