f150 and expedition wheel offset?

What offset do u need to tuck? I was looking at some 22s and they offered a +20 or +32?

My 23x10 that I had on my Screw were a +20

so a+32 would be way in and probley hit the frame when u turn?

I  have a +13 my old rims were a +15 and they worked well too

my stock steelies are +15 i believe and my 22''s are +20 with about a 1/2 to 3/4 inch clearance in the rear with out rolled fenders
