I'm a moron--keep it simple

Okay, as the title indicates...I have a 2011 F250 gasser. Currently have Michelin 265x65 tires on stock ford rims (20s)--from a F350. Truck is lifted with ICON 4.5" lift. Tires look like donuts and I want to go to 37s. Bottom line...will these rims be okay for fitment if I go with 37x12.50x20 Toyo MTs? Don't understand the backspace thingy. Second quiestion. Can the current tranny/engine/diff handle this size tire? Diff is geared 3.73. Last question. Will a full size 37 inch spare fit under the bed? Thanks for any help.

I dont think Toyo makes a 12.50 in a 37" tire - its a 13.50 from their website

To answer your question on weather or not your truck can "handle it." They don't call them Super-Duty's for nothing.

Short answer: NO

You'll need new rims with the tires pushed out more. The stock rims won't even safely accept the 13.5" wide rubber. Not to mention you'll be scrubbing rubber on everything
