Sorry graham I beg to differ, pressure, temp and volume of the gas within the tyre are all connected, since the pressure and volume can be considered fixed once set then the only variable is temperature (this directly affects pressure etc etc). The pressure within the tyre will rise a given amount for a quantity of heat input, which means if you can limit the quantity of heat that the gas within the tyre can absorb then you can limit the pressure increase and hence gain greater control over tyre performance and consistancy.
Since air is approx. 73% nitrogen the heat absorbtion rate will be no different with pure nitrogen, Right idea but wrong gas. I beleive Helium has the lowest heat absorbtion rate.
