about 2,500USD each last time I bought some. Then of course, you have to do the NDT for the rim on each change, and if that is outsourced, that runs another 2K USD each rim, more or less. At a 1000USD/Ton for gas, then that is about $10 saving per sector for single engine taxi, on the figures given. If you are paying retail, which is a fair bit more expensive than the airlines would be doing, then the nose wheel changes could be up to 7K a pair including NDT. That would mean you would want to get about 700 landings in between tyre changes to break even.
