Valve stem diameter

[rjsd1]

I am going to replace tires soon and go from d to e rated tire. I will be using a tpms and need to go to a metal valve stem. How can I tell what diameter valve stem to order without removing the existing stem? My wheels are the factory aluminum wheels that came on my fw.

Here are valve stems that will work with Ford aluminum wheels.Here I have them in my wheels.

Yep! The metal stems would not fit my aluminum wheels because of the recessed holes. Had to put in high pressure rubber snap in. So I don't know if I will continue to use my tpms or not.

If you can't figure it out ahead of time, you can look for metal stems that fit either size hole, like these Vs-416.

x2 on the aluminum wheels may have a recessed area around the hole that restricts what valve will fit.

You could call the trailer manufacturer with the last 8 digits of the serial number and ask what brand/model wheels you have. They should have a build sheet on their computer for your trailer. Then call the wheel manufacturer.

Thank you.

Installers always install new valve stems with new tires, so just specify you want metal stems rather than rubber. Let the installer determine the right diameter shank, length and mounting style (some have the nut on the inside for use on wheels with recessed holes). Places like Discount Tire will install metal stems w/o extra $$.

I've never heard of different valve stem diameters for street vehicles, but that doesn't mean they don't exist. My air chuck and gauges fit everything from by bicycles to my tractor trailer. Having said that, we did have larger valve stems on our 20 yard scrapers. I'm waiting to see what others say.

The diameter difference would be in size of the whole in the wheel that the stem goes through.

Apparently not. .453 and .625
