Wheel backspacing...help!

This is my first post on this great site and hopefully some of you can give me some info that I need concerning wheel backspacing.
I have an 07' tacoma access cab prerunner that has stock 16" wheels and stock 245/75/r16 tires on it. I have a 3" Toytec lift waiting to go on and plan to put 285/75/r16 BF Goodrich At's or Mud terrains on. I'm still trying to decide on wheels but my question is... What is the bolt pattern and Backspacing that I will need for this truck for these tires to fit. I don't want to order the wrong wheels or run into any unforseen problems down the road. Hope some of you can help. Thnx in advance.

 

So far on here I have noticed most saying that a 4.5" back spacing is required, but i don't know about the bolt pattern. Try this in search "any pics, info or links to Clearance?" LJackson has posted some useful pics their as a response.

my wheels i just ordered have a 5" bs

 

With 5" of BS, you may end up having to get spacers for the front wheels.

 

deafenantly go with 4 to 4.5", mine are 4.25/ about 4 and 1/4 inch backspacing, and they worked great for my 285/75/r16 BFG A/T's.
