Where to get presta valve stems?

[RedlineRacer]

I am guessing they are called presta. Atleast thats what the mountain bike industry calls them. They aren't the normal shrader valve stems that most wheels use. My wheels only use that kind. And I need two of them. Anyone know where to get them?

You have mountain bike wheels on your car?

If they're different than schreder valves how do you air them up at a gas station?

with a 50 cent adapter you can put on there

They have the same valve, but they mount different. Here's a pic.

that looks like a heavy duty (high pressure) schrader valve that you use for d load tires.

Try a custom wheel shop or high end tire dealer.

Try a bicycle shop, i know the shop i worked at carried the presta valves by themselves for tubeless mtn. bike wheels..
