Metal valve stems TST tire pressure

To avoid rubbing, take some vacuum line or fuel line. Split it and put over the valve stem. Keeps the stem from flexing while going down the road. Has worked great for over 2000 miles.

Metal stems wouldn't work on mine due to the diameter of the nut for the stems. They didn't machine the relief big enough on the rims.

I got metal core stems, but pull in place like a standard valve stem. They don't bolt in place.
