Nitrogen filled tires are becoming popular ?? Anyone doing this and getting good results??
I read on websites good things about Nitrogen filled tires.
NITROGEN:
is an inert gas and pure(air is mixture)
lacks moisture(air has moisture and produces moisture that may damage the wheels/tires)
does not oxidises(air/oxygen undergoes oxidation and may produce moisture)
larger molecule size( does not escape fast and not diffuses as air)
displaces air/oxygen in tire and thereby reducing oxidation
weighs less than air/oxygen(less weight of vehicle as a whole)
does not support combustion(air/oxygen supports)
consistent in pressure and volume -psi does not epand/contract like air (time and moneysaving, no need to check psi often)
helps in traction and handling(pressure and volume consistent)
increases tire life and quality
very safe in freezing/subzeroes(liquified temp-196, freezes at -210 )
please post your thoughts and experiences if you have any with Niitrogen filled tires.

I have no direct experience but it is my understanding that it is not very expensive to fill your tires and I also believe it can't do any harm so you might wish to try.

I had nitrogen put in mine when I replaced the tires. The difficulty is that I went from RFT with air to conventional rubber with nitrogen - so it is hard to guage the impact (if any) of the nitrogen.
I can say after about 3,000 miles the ride is like silk compared to the runflats and noise is down significantly. These improvements are no doubt 99% tires. In the end I went with nitrogen because it was not that much and comes with a lifetime refill and check included. I live about 2 miles from the tire dealer so every month I drive through and in 2 mins they check the pressures and will top up if necessary. So far there have been no pressure losses. Also where I live has pretty large temperature swings and the constant pressure provided by nitrogen may be more advantageous in those circumstances.
I am thinking of getting my wifes done just so I know she can drive through and have her pressure kept just right at all times. Correct tire pressure is a key safety feature.
PS: The red valve caps and nitrogen stickers next to the valves look okay too.

... which also states that nitrogen already makes up 78% of the air around us. Is the benefit of going from normal air with 78% nitrogen in it already to 100% nitrogen going to be that much for daily drivers and daily driving I wonder.

I was considering filling the tyres with Hydrogen, I have heard that it makes for more explosive acceleration...

Lol, I was considering to write the same thing

And putting snake oil in your engine will make your car go 22% faster. Anyone know where I can get any? Any snake oil salesmen out there? 
"Inert gas" - I think the stuff outside the tyre, ie air, is more worrying for reactivity than the stuff in your tyre
"lacks moisture" - only because it comes in bottles produced by freezing air, and therefore removing moisture. If you filled your tyres with a foot pump on a subzero day there would be virtually no moisture in there, and that would be free
"does not oxidise/corrode/combust/etc" - see point above about what's outside the tyre that matters more...
"larger molecule size" - actually N2 is smaller than O2, or at least very very similar
"weighs less" - yeah, the weight of air really bothers me. How can we stand living in it?
"consistent in pressure" - the crucial thing here is the amount of water vapour - this can affect changes in pressure with temperature. However, for 2 dry gases, it matters not whether they are N2 or gaseous uranium, the pressure/temperature relationship is identical - Boyle's law, in fact, been around since 1662, or about 13 billion years, or about 4022 years for any creationists out there.
"safe in freezing conditions" - this one really made me laugh
. How many people here have had the air in their tyres freeze on them? O2 boils at -182, carbon dioxide (<1% of air) may be the first component to liquify (or sublime to a solid more likely, depending on the pressure) but even that would never happen on any point on earth (around -78C at 1 bar)
