Can't see it. Air is 80% N2 anyway and O2 & N2 have the same specific heat capacity and O2 is slightly more dense at the same temperature. This could make a tiny difference to expansion (but tiny) and if you fill your tyres with air it's 80% nitrogen in the first place.
It really is snake oil, as Del said.
