I was leaning towards the mickey thompson sportsman S/R 26X12X15. Anyone running this setup that don't mind posting pics? I'm going for the prostreet look. The fronts are on mickey thompson sportsman 26X8X15. yes the truck is lowered. Please help

UPDATE: sent the rims back to the place I purchased from to exchange for 15X10's with 5 inch back spacing. Of course more money now, but hopefully now I will be able to run my wide tires without narrowing my rearend or widening my fenders?

So.... Glad to see you opted for the 10" wheels w/5" back spacing. It may be more for the wheels, but I bet it's less overall vs. swapping/narrowing the rear end or widening the bed (plus it WILL look better vs widening the bed).
That being said, you indicate you already have 26x8x15 MT radials on the front 8" wheels. 8" tire divided by 9" wheel (8" wheel = 9" overall width @ the beads) = .88" of rubber per inch of wheel width.
Your proposed rear size is 26x12x16. Those tires would yield 12" tire divided by 11" wheel = 1.2" of rubber per inch of wheel width or 73% difference. That calculation indicates your front tire sidewall will be s t r e t c h e d out slightly & the rear sidewall will be pinched (if you compare them).
Now, about that highlighted statement above..... The Pro-Street look is "bigs & littles". The rears should be taller. I like keeping them close to OE sizing (or taller if you must) otherwise the wheel well opening starts appearing HUGE visually.
A better choice based on your targeted look would be 28x12x15 if you had to be able to tell your buddies "yeah.... it has 12" wide rubber on the rear".
Visually, a 28x10x15 would still be as wide as the rear wheel & better match the front proportionally as viewed from the sidewalls.
Something to consider if a visual detail like this means something to you.....
