Is there an advantage to use nitrous gas on car tires?
Its not nitrous gas (brings to mind NO2…), but Nitrogen gas. I dont know if there is an actual advantage. While it is true that nitrogen does not expand when it gets hot like air does, the actual difference it makes is negligible. I have been to places that use nitrogen instead of air, at no extra cost, and I did not have any problem with it, but I did not notice any advantage either. As far as going fast on bumps, well, thats just silly.
