I didn't put steel wheels on; I took them off!

The stock wheels were steel. The new wheels are 15" alloy wheels - only 19 lbs.

My new tire/wheel combo is lighter than both the stock Sahara and stock Rubicon setup

And speaking of floating away... the wide tread and big sidewall should float on top of the sand at the sand dunes quite nicely. Can't wait to see how much more traction I have, and how much more turbo power I can put to use while climbing the dunes
