I leveled my truck and put on some Venomrex 20" wheels and some Toyo Open Country ATII 34s...aftermarket wheel and tire combo weighs 0.6lb less that stock 22" setup. Have noticed MAYBE a 3% difference in range
I can't for the life of me understand why Ford made those steps for our trucks with a glossy black strip in them...it's like asking for a problem.
I pulled mine off and put a set of Rough Country steps on instead...much better!
