1985 f150 wheel adaptors

I have an extra set of black fr500 rims and new tires.  I know the bolt pattern on  the 1985 f150 is 5x5 and the rims on the fr500 are 5x114.3.   I was going to buy adaptors so the rims and tires can fit. my only concerns are this. 1) rims are 17x9 upfront and 17x10.5 in the rear. am I going to rub upfront when I turn?  and will the rims at 10.5 rub in the bed and leaf strings?  bed is off the truck in parts get fixed.  so I cant just line it up and see if it will hit the bed.
