I'm all for using nitrogen in tires (tyres). In fact, I use 78% nitrogen every time I fill up my tires.
Now, to be truthful, there may be certain advantages to using purified gasses, but they are pretty limited. Hydrogen? I'm not so sure about it. It's light, but it's a tiny molecule, and tends to escape quickly (ever had a hydrogen balloon? they last 4 hours max, then the hydrogen leaks out of the balloon). Maybe Honda has a good tight polymer for their tires. H2 is also flammable, but I doubt this is a problem except in a crash.
The advantage I see to purified nitrogen is that it's dry. Compressed air always has a bit of water in it, and that's not good for rims, I'll grant.
So....do it if ya' want. The prices looked cheap enough for a one-time experiment, but a bit high for me to do it on a long term basis. Hmmm, I do have a tank of nitrogen in my laboratory. I have a tank of argon as well, but I think that would just slow me down
BTW, never, never, never breath in argon like you do helium. Helium is very light, and passing through your vocal cords, it makes you sound like mickey mouse. Argon is dense, and is supposed to make you have a deep voice. Trouble is, our lungs are like vases, and its really hard to push dense gas out. Sooo, it's really easy to pass out from lack of air.
