the coefficient of nitrogen is only .2 better at best (since you’re probably not getting a pure fill) so it’s not really worth it unless almost free. equate that to an expansion of maybe 3-4psi at at track day instead of 4-6psi (my experience with street tires).

just not worth it.

I pretty much expected the result of this thread would be that it wasn’t worth it, but it’s a good topic, idea to talk about.
