I have an 2007 Chevy Silverado 1500 WT. 2-whl drive, with 17 inch stock wheels.
I would like to Know for sure the wheel hole size for the valve stems. I cant remember for sure, its been a while. ive done some research an came up with .453 diameter, but I need to clarify to be positive before I start cutting off the old ones. LOL, Hopefully someone will know the size for sure. Thanks in Advance.

 

Honestly usually the valve stems I replace on wheels are "standard" size. I never actually measure them, because the new stems I need are usually located by the tire machine I am using lol

 

It's like when you buy a package of valve stems at the parts supply store... The packages are all lined up there on the wall.. They are very much all the same with the exception of their length. The next size up would be big rig stems, and there is no mistaking them
