save even more weight, put hydrogen in them, just dont get the tyres warm
fill it with H+ molecules, reduce the weight of the air in the tyres to 1/28th of current weight

It's all about Radon you fools. Nitrogen was so 2009

Thanks for your input guys. For $6 a tyre I'll stick to the nitrogen and I'll still have money left over for coffee and cake!
The only advantages I can see are that nitrogen is "dry" there is less scope for condensation of any kind in the tyre, condensation which could (for example) reduce seal effectiveness, cause larger flutuations in tyre pressure over warm/cold cycles (condensates, dissolves gasses on cool down, releases gasses and then evaporates during warm up. Would be more apparent in coastal and humid regions.
Pressure doesn't really matter what sort of gas it's using. While I'd be interested to see helium just to see if one can feel a difference, I expect the differences would lie in resonant frequencies, compression characteristics of gas.
Hydrogen for instance, contrary to norm is endothermic on compression. The more you compress hydrogen, the colder it gets instead of warming up. I expect there would be differences using exotic gasses.
Not Reccommended :
Radon ( /ˈreɪdɒn/ RAY-don) is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as the decay product of uranium. It is one of the densest substances that remains a gas under normal conditions and is considered to be a health hazard due to its radioactivity. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Due to its intense radioactivity, it has been less well-studied by chemists, but a few compounds are known.

For balance, you might like to look at the stated advantages of N in your tyres on Nitrogen in Tires : Information about Nitrogen Tire Inflation News, Benefits, Generator Dealers, Location Finder & More
The physical and chemical properties I refer to in my previous post remain valid and are indisputable properties ("you can't argue with science") , and my contention stands that for the average Joe who routinely checks his tyres, the benefits are minimal to zero. The costs associated with weekly or even monthly N top-ups would far outweigh the supposed savings from reduced tyre wear that might be attributable to "a lesser tendency to pressure reduction" via "rubber seepage", most of which is in any event is more likely the result of poor fitting rims and valve fittings. And if you are checking as frequently as weekly, which most people don't, then you can much better afford to use air for free, especially if you check tyres when they are at the same ("cold") temperature, with little or no risk of pressure loss between checks.

Even worse than Radon in your tyres would be Uranium Hexafluoride UF6. Within a reasonable range of temperature and pressure, it can be a solid, liquid, or gas. Solid UF6 is a white, dense, crystalline material that resembles rock salt. It's very expensive, corrosive, radioactive, and explosive. Uranium hexafluoride does not react with oxygen, nitrogen, carbon dioxide, or dry air, but it does react with water or water vapor, sometimes violently, as in inadvertent bulk release from storage. For this reason, UF6 is always handled in leak tight containers and processing equipment. When UF6 comes into contact with water, such as water vapor in the air, the UF6 and water react, forming corrosive hydrogen fluoride (HF) and a uranium-fluoride compound called uranyl fluoride (UO2F2). Not the best stuff to be around. Of course, y'all needed to know this!

I been using Glider fuel in the tyres & tubes for as I knew how too & I will still use it.
for Glider fuel
I got some tyres fitted today (2nd set in 3 weeks from the same place) and they didn't even attempt to sell me nitrogen inflation, although they offer it.
But...I did hear them on the phone and in person trying to sell it to "Mum and Dad" consumers, so it seems it's just a margin builder for them...
