Default What is the purpose of dual valve stems?

Just like the title says, what is the purpose of dual valve stems? Something like these Enkei wheels (link). I think I also saw a set of Volks like this. Anyone know?

Exclamation Just a guess!

The second stem could possibly be for tire pressure monitors? I don't know if they typically mount on the inside or outside of the wheel?

Weird...
I would have put them opposite of each other for balance instead of next to each other.

I know some racing wheels have a second stem for an inner liner.
Like an innertube which is pressured and then pressure between it and the actual tire.

The dual v-stem system is actually to insert nitrogen as well as air into the tire. It keeps the pressure at a more constant p.s.i. as I was informed. Track use of course.

I know Nascar uses an inner liner, like a tire within a tire, at larger tracks and these rims use two valve stems. As for one valve for air and one for nitrogen, why would you need two stems?

To be unique. Inner liner stem isn't at that location. If you use nitrogen you might as well use 100%. Moisture is your enemy.
