Small 285's?

I've seen a few post of people running 285/75r16 tires on stock wheels and 2.5-3" of lift, with no wheel spacers. The last one I read was using Revos. Anyone know which 285s in an AT tire run on the small side and likely will work without wheel spacers?

 

I have 285/70/17s on my stock wheels on my 4runner with 2.5" lift.

 

Link to these posts? I find it hard to believe.

 

Here is the first one I found:

I bet those ties would rub offroad when flexed with only 1.75" of lift.

Also the reason they weren't hitting the UCA was likely because they were overinflated by 10+ pounds, combined with the shape of the sidewall of the revo's (which is what you were getting at in your OP)
