I just installed mine today, ko3’s tho. 2” OME. Having to trim a bit of that front mud flap and bend the inner plastic wall a bit but they “fit”.
I'd love to see pics of 285/70/R18 set up on LC200

Those are 285/70/18s? Have any other pics you can share, truck looks great!
Yes sir they are 285/70’s. OEM wheel and no spacer. I might add a spacer after cutting, just need to figure out how much I can get off that front inner wheel well.
Don’t have many pics yet but included what I have.
What’s your suspension set up here
Bilstein set at 4 with rear 30mm spacers
Is this lifted?
Thanks. Could you tell us what the actual measured height of the tire is?

Why does everyone keep calling a 285/70 a 34" tire, its a 33" tire. 285/75 shows 34".
Shorthand terminology gets everybody confused - never truer than in a tire discussion.
285/70R17 tires are indeed generally referred to as a 33" tire, but this thread is about 285/70R18 tires which are generally about 34".
HTH
P.S. What is so hard about fully describing the tire in question? A tire can be any of the following (using 285/70R17 as a hypothetical):
- LT-Metric: LT285/70R17 Load Range C,D or E
- P-Metric: P285/70R17
- ISO-Metric: 285/70R17 121 SL or XL
All different construction specifications, Load Limits, and Recommended Cold Tire Inflation Pressures.

Gosh I've been involved with machines and vehicles for decades and have never realized this, I had no idea RIM size would matter for overall height on the same metric size tire.
Just FYI:
(Image source: Guidelines for the Application of Load and Inflation Tables)
Using a 285/70R17 tire for example:
285 is the section width of the tire in mm
70 is the aspect ratio, or in this case 70% of the section width (199.5) in mm which is the height of the sidewall.
So, without the rim diameter, it is not possible to calculate the overall diameter of the tire.
The overall diameter of this example tire would be:
Sidewall height x 2 = 199.5 x 2 mm = 399 mm
Rim diameter = 17" x 25.4 = 431.8 mm
Overall diameter = sidewall height x 2 (399 mm) + rim diameter (431.8 mm) = 830.8 mm or 32.7"
Depending on the manufacturer of the tire, there are obviously slight variations in overall diameter from one brand/type/model of tire to another, but generally all of these fall into the overall term of a 33" tire.
Clear as mud, right?

Yeah, the picture was taken with the truck on Dobinson's MRR.
Am I inferring correctly that an 18x8.5, 40mm offset will work with a 285/70/18 with minimal to no mods?
Yeah, at first it might seem confusing. Just imagine a tire sized 285 (width, fixed) 70 (aspect ratio, meaning sidewall (not overall tire) height relative to width, so also fixed at 70% of 285(mm)). So with that width and sidewall height in mind, both fixed, image that size tire on both a 15" rim and a 22" rim. One is clearly much taller than the other, rim diameter being the only variable. That helps me at least.
Too small
It should.. though you will likely need to move the front of the fender liner forward and remove the mudflaps behind the wheels. It will be very close and depends on the alignment.
So maybe go with 285/65/18? This is a rig that will be used mostly on road with light overlanding on weekends
Depends on what you want, but definitely an easier setup to fit. And a very common size up over stock. Small to no chance of rubbing.
I just pulled this exact size off from my rig and have them sitting in the garage. Ended up going bigger.
