The Model A 1928-29 wheels are probably a little rarer than the 1930-31 wheels - this due to their method of construction with an "inturning" rim bead. The bead catches water and the inturn bead rots out from the inside. The 1930-31 wheels do not suffer from this defect.
The Model A "AR" type wheels are probably the rarest in numbers and most difficult to find - but demand for these is limited because of the limited number of AR cars remaining. So value for these tend to follow the later 1928-29 wheels and probably for the same defect.
Around here a good usable 1928-29 standard wheel runs about $25. Better quality a bit more perhaps. AR wheels perhaps $35 when you find them. 30-31 wheels perhaps $25 but only if they not all chipped up on the paint.
They have an inherent value. You'll do better selling rather than junking them, in my opinion, and most probably be of help to someone who is involved with A's.
They are also good buried in the ground as dead men to hold retaining walls. Cable around the retaining wall posts then back to the buried wheel.
They’ve been holding up ours since 1934. My Grandfather did it........,
As stated above, a Model A wheel in any condition makes a great rack for an air hose, extension cord, etc. and it looks good doing it!
Any flea market, yard sale will give you $10 if they are that bad.
scrap yard is a loser move...helps no one
