You can buy the correct rims for a 1655, 15 X 8, with a non standard offset from Wold's in St. Ansgar, Iowa.  641-713-4751.  Apparently the manufacturers could not get the non standard rims, as my 1655 had the wrong rims as did a John Deere 4320 that I bought.  With the correct rim, they can be installed with the nice looking side of the rim out.
