Post 10 does not show a rim blow.
Might help to post a pic of yours.
1-Pretty sure the rim blow has phillips screws on the back to remove the center.
2- Then remove the large nut.
3- Next use a puller to remove the wheel*.
*Most parts store pullers may not have long enough bolts in the proper thread size for Mopar wheels.
A- If your wheel does have the "can" like a "tuff wheel" does (post 10) remove the three nuts before you can access the large nut (step 2).
On a tuff wheel, the horn spring retainer comes off with the wheel (step A).
I've not removed a rim blow, so not sure about that, but remove the wire. Should be a spade connector.
