This was not a fair comparison. They compared a white car with oxygen in its tires to a blue car with nitrogen. Everyone knows that blue cars are faster!

 

It would have been even faster if it had flames on the fenders!

 

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."

 

Just check your tires pressure a few times a year and add/remove air like a normal person, most notably when there is a significant change in temperature between seasons.

 

Hot = Increase in Tire Pressure

Cold = Decrease in Tire Pressure

Make a habit of Checking every month just to make sure , your getting the right amount of Handling from your GS with the Correct Tire Pressure.

 

This is what I was going to post. I used to do pre-flight checks on F-4's in the Air National Guard. Check the tires & PSI, top off with nitrogen only!
