I just picked up an 89 F150 XLT Lariat. Interior is in great shape with no rips, scratches, or cracks at all. The exterior will be getting a complete paint job in the next couple of weeks.
I will also be replacing the stock wheels/tires and this is where my questions begin. More than likely I will be going with 15's or maybe 16's. The truck is a 4x2 and everything is bone stock at this point. I will be putting a 2 inch level kit on the front to raise it up, (maybe get some F250 springs if I find some). What hub bore should I be looking at getting in the wheels?
Our bolt pattern is 5x5.5 correct? I've also seen 5x139.5mm listed. Are they interchangeable or would the 139's give me problems? How much offset and tire width would be recommended for this setup?
Also, in regards to offset, does that primarily refer to how far out your tires will extend past the fender?

Sorry for the rambling but wheels/tire sizes have always been a pain in the a$$ for me for some reason.

Thanks guys!

 

if you go to tire rack and enter your vehicle they will list all the rims they have that will fit

 

and tires to

 

All the factory rims have zero offset which works fine with stock sized tires, but with oversized tires you don't want any more than about 4" of backspacing because it starts to produce rubbing on the trailing arms and swaybar. You would also need a least a 10" wide wheel before it would stick completely outsize the wheel well, an 8" with 3.75" backspacing will bring the tire flush with the top of the wheel opening.

FWIW..
Backspacing is the distance from the hub mounting surface to the rear edge of the rim.
Offset is the alignment of the hub mounting surface with respect to the centerline of the rim.
Rim size is measured from the inside of the bead.. not the outside.
