Rim size Question

[Slip]

I just got a set of BfG/mud terain 33x12.5x15....and I need rims.
I have a 2003 FX level2, 3 inch body lift. she has all factory brakes/rotors and calipers. I think the level 2 has beefier front rotors/calipers, because I bought a regular 15 inch winter rim and it would'nt clear the caliper when I torqued the nuts down.

The factory rims are 15x7 forged-aluminum Alcoa...with 4 1/2" backspace
(+6 offset)(I think).

I wanted to know if 15x10 rims with a 3 3/4" backspace with -38 offset well fit my truck??? or will i need spacers?

if your stock rims have a 4.5" backspace and the aftermarket ones have a 3.75" backspace then the new wheels are further away from the caliper and tie rod ends. that being said, the new rims should not rub on the inside, but that means that they wil stick out about 4.25" more than the stock ones. when turning the tires might hit the fenders or the bumper.

just my .02 hope this helps
