What's in your tyres???
Discussion
Having done some research:

The major benefits of nitrogen filled tyres, over compressed air, are that they stay inflated for longer - reducing tyre wear, improving road handling and increasing fuel efficiency. Kwik-Fit chose the Uniflate Nitrogen Inflation system following successful trials in the Netherlands earlier this year, which led to the installation of over 200 systems countrywide.
Nissan GT-R introduces specially developed tyres with nitrogen filled at factory:
Jeremy Clarkson reviewed the car in June 2008 and in his final verdict announced it “Unfathomably good”. He also stated “The attention to detail has been extraordinary. For instance, the GT-R’s tyres are filled with nitrogen because ordinary air expands and contracts too much. And each gearbox is specifically mated to each handmade engine”
Still sounds like a load of b
ks!!! But now I also think it's a money making load of bks!!! If you keep an eye on your tyre pressures on a regular basis you'll save yourself the £8 outlay... They'll probably want twice as much to fill your tyres too as they are twice as wide...

For no particular reason other than that what they put in them, but i have mostly nitrogen in mine, cant tell the difference.
The main benefit with it is that it is a dry pure gas as opposed to atmospheric air which contains water, so doesn't expand as much as the tyres get hot, as i said cant tell the difference.

Bit like my breath at the moment, just had Kippers for tea
