Right now I have stock wheels, I think they are 16.5 by 8 inches, but i would like to get a little fatter tire tucked under there, but do not want it outside the fenders. How to i caculate my current back spacing and the addition i want to add, it looks like i can get a couple of inches at least with out hitting the inner fender.

Are these the stock steelie wheels you have on there? if so they are most likely 16.5x6 or 6.5" wide. not very wide. I ran them for awhile.
I believe the stock backspacing is 4.25", I am running a stock H2 wheel with 5.25 or something like that of back spacing, they are tucked in alittle farther in the wheel wells than I prefer, but not horrible, they definately do not go out side the wheel wells like my 3.50" back spaced wheels did.
the H2's are 17x8.5" wide too i believe,,

Just remember,,, the further you space the wheels out from the mounting surface the greater the leverage effect on the front end parts.....
ball joints,,wheel bearings both suffer....

An 8" wide wheel with 4" bs means the mounting flange of the wheel is in the center of that 8" width. If I'm reading you right, you want more wheel in towards the frame so as not to stick out beyond the fender line. An 8" wide wheel with 4.5" bs would accomplish this goal.

In addition, your truck will handle differently, and possibly in a way to be unsafe. You don't want to find that out in an emergency situation.
And, of course, wider tires mean more weight which means less power, poorer gas mileage, and slower acceleration and longer braking distances.
Looks like he has a 3/4-ton 2WD. I don't think the front end will suffer from upsizing the tire a little. We all know the 14BFF is fine with WAY more. Doesn't sound like he's even lifting it. He wants to keep the tires under the fenders, so I don't see how there is any risk at all here. It's just a question of what hits and what fits.
Offset:
Backspacing:
So if you know the width and the backspacing, you can calculate how much more is going "in" towards the tie rods/springs and how much is going "out" towards the fender lip.
