Anyone know where you can get the high pressure valve stems like the ones on the OEM wheels. It looks like chrome or stainless?--Thanks Ken

Any place that sells rims should have them.
Look into the valve stems that use a nut to hold them on, sorry I forget the proper name of them.

Yep, any tire shop should have them...or, if you can find a guy that's willing to look them up, most parts stores have them or can get them too
