Which 16"x8" rims don't hit calipers on 3rd gen. 4Runner with 15" calipers?

Just for clarification, do you have stock 16" rims, or stock 15" rims? If you were luck enough to have 15" rims from the factory, you can run whatever rims you want (I'd stick with 15's, the tires are cheaper). If yours came with stock 16" rims, you cannot run any 15" rim that I'm aware of.

It seem like an advantage if you are planning to stick to 15" rims and tires,
but if you would prefer to use 16" - you may have a problem.
I bought that 4Runner with OEM 16"x7" alloys - they fit perfectly, like OEM should.
Well, I wanted to upgrade my wheels to 16"x8" to go to 285's (yes I know I can run them on 7" rims)
and in future to 315's... and I got to troubles.
The wheels I bought (M/T Classic II) hit the brake calipers - they are too close to the center of the hub
and stick out enough to hit the surface of wheel that touches the hub.
Some people simply "shave" their calipers a little to correct that.
For now I'm running them on 1.5" spacers (Marlin Crawler - great quality stuff), but the tires rub
on full turn when they move up, even that I have 1" BL and I did cut and hammered lot of metal in the wheel wells.
I wonder if there are any 16" alloy rims with 4-4.5" backspace on the market that do not hit the 15" calipers.

I had the same problem with my 4runner. I have 16x7 stock and wanted to upgrade to 16x8. I purchased some Eagle rims 16x8 and had 285 bfg mudders on them. The people who installed them said they were hitting the rotors and couldn't even move the 4runner at all. Is the rotor the same as the calipers? the rims I purchased were backspaced about 1/2" more than stock to move them out 1/2". but still didn't work. I got some 1.5" wheel spacers but do not know if that will help. I will try someday. For the meantime I have 265/75/16 on them, because I really needed new tires.

Some clarification: rotor is the disc... that rotates, then there is the thing
that does not move and is wraped around the disc - that's caliper.
You actually can have 16" rotors and calipers.
And then the max diameter of that setup could be too big for your wheels.
My problem is not a too big diameter of the setup, but rather too big width of the caliper.

If what you get does rub, it won't be much and just grind the calipers down where they rub, you can tell for sure, or get some spacers, but grinding is a heckuvalot cheaper.

BTW out of curiosity how heavy is the 16x8 Rock Crawler rim?

You have it all back wards. People who have 16 inch rims from the factory who want to put on 15 inch rims and tires will run into problems with rubbing the larger rotors and calipers. If you want to UPSIZE your wheels from 15 to 16" (which I have no clue why you would want to do that, 15" tires and wheels are cheaper and have a larger selection of tires, plus your braking would slightly decrease with a 16" wheel) then all you have to do is get the PROPER backspacing, 4.25" should work fine. That's what I ran on my 96.

The truth is too that calipers on 15" rotors are simply closer to the center than calipers on 16" totors.
So any wheel you are going to put on them needs to accomodate for that by kicking out it's spokes at a bigger angle.
Here is some illustration of the problem:
Top left: 15" rotor, Caliper A, 16" wheel A, backspacing A - PROBLEM
Top right: 15" rotor, Caliper A, 16" wheel B, backspacing A - NO PROBLEM
Bottom: 16" rotor, Caliper A, 16" wheel A, backspacing A - NO PROBLEM
The left pictures feature the same wheel, but different size rotors - one hits the caliper the other doesn't.
The top pictures feature the same rotors, but wheels with differnt angle of their spokes - one hits the caliper the other doesn't.
All three pictures feature the wheels of the same size and backspacing, but some with different angle of the spokes.
If you want to UPSIZE your wheels from 15 to 16"
(...) all you have to do is get the PROPER backspacing (...)
