2 valve stems???
 

Ok. I pride myself on being a car guy,but this is alittle perplexing. I just got these C1M wheels and they have 2 valve stems on them.
What gives. I tried searching "valve stems" but got nothing. If you could direct me to a thread or search word that would help.
Thanks.

lets you do different things.

1. Purge and store air
2. Equalize pressure between wheels
blah blah blah. If YOU did a search it would come up.

Primarily used to evacuate air when filling with nitrogen. But also useful when you want to run a small portable compressor in one stem while checking pressure in the other.

Ok. thanks alot guys.

Pit. I did do a search. Try it and you will see. I typed "2 valve stems" and no results came up. Try it. Maybe I should have tried some other key words,but i appreciate the help.
