Cool.
I would add that an 18x7.5 police wheel at 31# is not an exact comparison to an all steel, 20" factory style poverty wheel. Perhaps it would not be the 60# I posited above, but it may be very near 45-50#. Nearly double that of a lighter weight aluminum 15" wheel or even a race weight steel 15" wheel. I have 15x7 steel racing wheels that are 21#, so your 18x11 at 29# is impressive. Congratulations.
I personally can not stand the look of original plain steel wheels and don't understand the attraction to them, but that is my preference. If you and a percentage of other mopar owners are happy with them, or an 18" aluminum copy, Boo Yaa !
