Wire wheels for late 1929 Packard 626

[31Buick96S]

I am considering the purchase of a 1929 Packard 626 Coupe. A friend suggested that the wheels on the car are incorrect and likely 19". As the photos show, the car was delivered on 7/3/229. The dismounted spare wheel/tire seems to show an 8 lug pattern that would be cover the lug bolts by a hub cap. The 4 wheels mounted on the car are identical and have the pictured hub cap . The tire size on all 5 wheels are 6.00 -20 as shown in the close up of one tire.

1. Can anyone tell me if these type wheels available on this car originally?
2. Are they 19" or 20"?
3. Does anyone recognize the manufacturer of the wheel?
4. The tire size confuses me if they are 19", is this even possible?

Thanks for any insight anyone can provide.

The hubs appear to be 31 Packard (with larger hubcap), but the rim and the lock ring look a little heavier than normal matched to I thought 31 Packard's were 19" verses 20".  I am not sure what to tell you, though it is not the traditional wheel for your series Packard and wires in good shape are not all that easy to find, as well as costing a pretty penny.  if you must have the correct wheels I would think about disks as they are more plentiful in nice condition.
