Looking at picking up some new rims/tires

The rims/tires are 32x11.5x15 which if my math was right was a 295/75/15's and have BFG A/T KO's mounted on them with tons of meat left on them, they look pretty awesome... HOWEVER, will they fit my Taco? That is the main question here. As plenty of you know I am lifted all around 2.5" up front and 2.25" in the rear. If anyone has any pics of what these look like mounted in silver or black that would be highly appreciated too, though I will most likely paint or powdercoat them anywho. The tires on my 18's are starting to get thrashed and kind of chunked and Chrome has always been too much bling bling for me anyways.

Here's what they look like:

 

15's wont fit on a 2nd gen.

 

What is the reason for that? Rotors? Calipers?

 

primary reason that I know of is that they wont fit over the caliper. I know that 16" wheels just barely clear the calipers. There may be more issues with other stuff like the spindles or hubs or rotors, etc. but I dont know because I have always stopped looking after just knowing about the calipers.

 

Damn, they seemed like some darn fine looking rims to pick up. I guess that cans that idea. The tires alone is what had sealed the deal for me.
