I would like to know if anyone has had the experience of filling dry nitrogen in their car tyres? The sales pitch says that dry nirtogen is a better choice as (a) nitrogen, having larger molecules, dissipates at a lower rate (than air) through the tube walls and (b) the lack of moisture in the nirogen keeps the tryres running cool.

Due to both, the trye pressure remains constant over larger periods (one needs to check pressure only after 6 months).

Any opinions would be welcome. Chennai has at least one such outlet.
