Thanks for the replies and photos! I appreciate it.
My brother put a set of 7.10-15's on his '53 Coronet and they seem wider that the Moroso or Stahl 7.10's. If a set of "new" bias ply 7.10'-15's will fit on a 4 1/2" wheel, that is probably the way I will go.
RMCHGR: How wide is the treat pattern on those Stahls that you have?
