Nitrogen or not, it is still a gas, thus the ideal gas law still applies. Although has slightly better characteristics than air, but the keyword is SLIGHTLY, and as such, any and all nitrogen filling is a ripoff, IMHO. I usually fill my tires with a healthy mixture of mostly nitrogen (78%), some oxygen for a good measure (about 21%) and some other gases (argon, helium etc.) for a great taste!
