you can fit 285/75R17 without cutting or BMC, but you would need a suspension lift, aftermarket bumper and UCAs
I am running those on my rig, but i have ICON stage 7 with overland springs in rear and 700lb springs in the front.

The 285 is the width, so at full steering lock, the edges of the tread are what rub on stuff. So, yes, the 285.
If you want something with more traction ASAP, get a 275 series tire instead of a 285. People are doing 275 with maybe a front splash guard push. No lift, no mbc, no nothing. 275 is very safe and gives you obviously 10mm more width.
I'm currently running 285s with a 2.5 lift up front, 2 lift in the rear and no aftermarket UCAs. I have heaps of space up front around the front splash guard, but I rub at full steering lock -gets way worse if the suspension is compressed while at full lock.
I'm trying to see if I can get away with maxing out my caster angle in my lower control arms. If that doesn't work, I'll get aftermarket control arms.
One thing to keep in mind is that 4runners are like finger prints in how they respond to lifts and bigger tires. Assuming people are going with 285s, one person might rub up front and others may not. Some people report just needing UCAs and no body mount chop and others say they needed both (UCAs and a BMC). So, it's a bit of a toss up. Also know that there's something called "driver's side sag" with our 5th gens where the driver's side is actually lifted more than the other corners from factory because it's heavier. That's probably why I'm only rubbing on my driver's side front and not my passenger side.
$0.02. There's a lot to plan out so I wouldn't rush to get a quick solution otherwise you may end up paying for things 2 or 3 times over.

2019 Pro here
Just got my 19 pro and wanna swap tires. Any pro owners in here that can advise on what they have done, and what fits? I had some 285/70/17 on my 17 taco pro with a level kit, but I am having a tough time finding info on this for my r 4runner.

Page 1 has a big ol' beautiful chart on what fits and what will require some modification

285/75R17 is the exact same height as 305/70R17, but narrower. I put 305s on my truck earlier this week, and they fit with some trimming/hammering/BMC/lift/high caster from aftermarket UCAs. I would imagine that the 285/75 would be a tad bit easier to fit due to the narrower width. Wheel size also dictates what and where the rubs will occur. I am running an aggressive wheel size: 17x9 -38 offset.

Yup. I read page one. I was unsure if the ride height of the Pro would effect the fitment chart, or if there is even a ride height difference between 4Runners. I literally bought this two days ago.

The Pro is just essentially just leveled in the front (about .75") compared to the other models.

I'm sure it's been asked a million times and I did a scan, but will 285/70/17's fit the TRD Pro wheel? Based on the chart it doesn't look like they will.

It can vary by tire. If you know what tire you want, go to the manufacturer's website and look for the spec page. It will tell you what the acceptable/recommended wheel widths are for each tire model/size.

Installed 1.25 Spidertrax spacers on my 17x8.5 -10 VTX Rogues. So basically running 17x8.5 -42 now. Still running 285/70/17 KO2s.
Without the spacers, all I needed to do was trim the front bumper a little and relocate the fender liner. After installing, it looks like I'll need to cut some more off the bumper, move the fender liner forward a little more, remove the mud flaps and get a BMC.
When turning normally, the tires barelyyyy clear the body mounts, but the rub marks indicate that it must be hitting under certain load.

So I have a question here:
I am looking at 2 options currently:
Option 1 - 275/70/17 with TRD Pro rims.
Wildpeak - 57.1lbs
KO2 - 55.18lbs
Option 2 - 285/70/17 with FN or SCS Wheels
KO2 - 50.33lbs (C)
Basically my question is.....am I better off with a 275/70 that's a heavier overall package as a wheel/tire combo, or better off with a 285 package that's lighter efficiency wise for losing power and speed?

There is no right or wrong answer to this question. Are you going to install a lift? If not, probably better off sticking with the 275 unless it never sees anything but parking lots.

Could always go 295 on the FX Pro wheels. You'll have to do the fender liner mod but you're going to have to do that no matter what you do.
