Therefore you don't have to check the tyre pressures as often. Maintaining temperature Heat is one of the major factors in a tyre's life. The cooler a tyre can operate over long distances and excessive suburban work [in accordance with recommended cold inflation pressures], the longer the tyre will last. Nitrogen being a gas doesn't expand or contract resulting in better cornering and road handling, and therefore increasing the tyre life and reducing the risk of blowouts. This whole paragraph is erroneous and overlooks multiple physical laws, unless you live in some parallel universe where things like the ideal gas equation Norbie quoted above are irrelevant. Nitrogen has the same capacity to leak out of holes as air does (remember air is 79% nitrogen). I would have thought checking tyre pressure would be mandatory as regular maintenance, even just so I could make sure my precious $15 per tyre nitrogen fill is being lost. Increased wear from incorrect tyre pressures will quickly counter any gains (real or perceived) made by filling with nitrogen. One of the features of a gas is that it expands and contracts - this state of matter sets it apart from solids and liquids which are noncompressible (not strictly true but for the the sake of this discussion, take it as given). Given that gases are compressible, if contained in a tyre then this will allow the tyre to deform. This deformation of the tyre will occur irrespective of which gas it is inflated with and will be of the same degree for the same inflating pressure. It is this deformation that causes heat to be generated in the tyre. Heat is also generated by friction with the road, direct conduction of heat from road surface to the tyre, and conduction and radiation of heat from drivetrain components (wheel bearings, brake components) and probably a myriad other ways. The only way there could be some difference is if there is a VAST difference in the expansion coefficients of air and nitrogen. I now suggest you find me/us this data, and/or the results of you randomized controlled double blind study before cutting and pasting absolute rubbish.
