I plan to replace the tires on my 1935 Packard Twelve, and I want to switch from whitewalls and wire wheels (as it is now) to blackwalls and wheel discs. I have the wheel discs that are original to my car; they were on the car until 2007, when it came into my possession. But I was hoping I could get advice on how to install them. I know how the discs clip on to the wheels. That seems easy. But do you need some sort of valve stem extenders, to go from the valve stem on the wheel out through the opening in the wheel disc so you can inflate the tires without removing the discs? I assume something like that is needed. The discs I have have old valve stems, so I assume there was once something mounted like that, but I don't know what is needed. Any ideas?

I bought these for my 55. I imagine the tire stems must have just been longer back in the day.

If you need longer than that and have tubeless tires, you can use truck stems.

I should have been a little clearer. I need longer extenders, flexible ones a few inches long. While you can get such things easily on Amazon or at any auto parts store, the ordinary ones you would buy don't have a way to mount them on to the wheel disc. The wheel disc has a large hole that looks like it's designed to hold the valve stem extender in place. But what holds the valve stem extender to the hole?

Pictures of the disc attached.
