For those who have aftermarket wheels......do you have a rubber valve stem or metal? Is metal better, rubber or does it not make a difference

 

I've had both and it didn't make a difference. The metal looks nicer and costs more though.

 

yeah, I don't think it makes a difference, but metal looks sharper, especially with chrome rims. And I believe I bought metal ones at Pep Boys for about $2 each, and they last at least the life of the tires, so price isn't all that much.
