I don’t know. I was mentioning what I’ve run and how they worked. If it were me I’d take various measurements of how much space you have with the current tires/offset in various stages of turn, ~1/2, 3/4, and full lock. And see if there is an extra ~1” of clearance at every point.

Been following this thread for a while now and found this and many other threads super helpful in trying to decide on wheels and tires. A big shout out to all those who answered questions and provided their experiences. I had debated a long time about which tire size to go with and wanted to share my my thoughts for others who are reading. I ended up going with EvoCorse DakarZero 17x8 ET 40s in Matte Black and Falken Wildpeak AT3w in 285/70r17.
A few notes about this: My use case was that this is my daily driver and I will be doing a lot of driving on the highway to get to skiing, hiking, mountain biking, and to get to our cabin where we will do a lot of fire service roads, light overlanding, and camping. We also spend a lot of time on snow and ice. I won't be doing any rock crawling, at least intentionally. I wanted to go as big as possible without doing a lot of trimming, shifting liners, KDSS relo, or obligating myself to make other mods and I wanted to maintain as much of the original geometry and scrub radius while still getting a 17 inch AT wheel and tire setup that looks good. I am so glad I went with the smaller tire size, which by the way, is not that small unless maybe comparing to 35s. I do have slight rubbing on the passenger side front rearward mudflap in full lock in reverse. I don't see or notice any other rubbing and I don't hear any other rubbing except in this one scenario. I was a little surprised by this but it seems pretty minor. I could heat up the flap but I am scheduled for a BP51 lift in late May/early June so I will take care of it then.
I think the setup looks great, the feel and performance of the rig is way better, nowhere near as much of the marshmallow feel, and I can take corners at faster speed and it overall just feels more robust. That said, I do feel a few more bumps in the road due to the E rated tires but worth the trade and to be expected. Noise is minimal and I can't tell a difference compared to stock even at 80 MPH.
All in all, happy with my choice and it really does come down to what you want to do in your rig and how you want it to look. I was always thinking I needed the next size up when in reality, the rig is super capable already so I didn't feel like I needed to go any bigger. A couple before and after pics below:

After.
By the way, I do have the caps for these wheels, just haven't put them on yet. Will do that and post photos as I know some have wondered about the caps.

Yes, please!

I’ve had KO2 tires before on my OEM 20” LX570 rims for about 15K miles (still have them for sale if anyone wants them) before finding a set of TRD BBS Pro rims. It’s time for new tires and was considering these LT275 /70 R18:

I’ve got a stock suspension, from the chart it looks like people are running this size without rubbing, any concerns?
Thanks!

What size KO2 were you running on 20" and what was the experience? I'm not planing downsizing due to big brakes.Be patient, I’m a tire idiot.

LT275/60 R20.
I liked them fine (had a set on my 4Runner previous to the LX) but I don’t really have much experience in this area. I’m pretty sensitive to noise issues and never had a problem with these.
Thanks. That is 0.01" from 33" 
What did you do to prevent rubbing? And how was the LX gearing doing? BTW what year is your truck?

I was running stock suspension & OE wheel with this size and did the normal clearance go. Had a bit of rubbing on the kdss at full lock. However, I think the Mickey Thompsons run on the larger size of the LT 275/70 R18s.Be patient, I’m a tire idiot.

2010. I don’t recall any rubbing issues, even in L.Thanks. That is 0.01" from 34"

I had KO2 ‘s on my 20’s. They were pointless since Even with 33’s didn’t have enough sidewall to air down or feel safe off road.
I don't bother to air down. Just to have a bit more sidewall compared with the very low sidewall on the OEM size.
If you aren’t on the type of terrain you need to air down for you likely don’t need an AT tire. Also even without airing down I had a couple close calls for pinch flats. I’m on 17’s now with 285/70-17.
For what I’m talking about watch this video starting at ~11:45. This new defender is on 20’s with 33’s…. And weighs ~1000 lbs less then a 200

Besides the concern of short sidewalls which is legitimate, I would also caution running 275 tire widths on the stock 20x8.5" wheel. Note the LC wheels are generally 8", and with taller profile sidewalls, improves bead retention over a stock 8.5" width LX wheels fitted with 275s.
The bead retention of a relatively narrow tire on a wide wheel is a bad recipe. I personally witnessed a buddy's car loose 3x tires in less than a 1/4 mile. Bead would come off with relatively minor sideload causing further carnage.

I'm not in that kind of terrain and I'm not really looking for a true AT tire. I just need a bigger tire. As most people that install bigger tires install an AT or even more aggressive that's all I have to go about figuring size that will fit. I also need one set of tires as I do not have storage space and that set has to be above average in snow. I was thinking Defender might be a good solution.
My size options on 20" that are 285 or larger (to take into consideration what @TeCKis300 said) are:
285/50R20 - 31.22" OEM, Defender available
305/50R20 - 32" not much of a difference
285/55/20 - 32.34"
275/60/20 - 32.99 for reference. Defender available
285/60/20 - 33.46" not a popular size so it might mean trouble if needing to replace one tire. Not sure it fits. Defender available
295/60/20 - 33.94" I don't know if it fits. Defender available
285/65/20 - 34.59" too big. Defender available
If I could distill this list down further and add a few opportunities: Many of these can be found in Toyo AT3s
305/50R20 - 32" not much of a difference
285/55/20 - 32.34"
33x11.5R20 - Very limited availability
295/55R20 - 32.7"x12.2 - Available in several popular AT tires, no Defender
33x12.5R20 - Available in several popular AT tires, no Defender
305/55R20 - 33.2"x12.4"
285/60/20 - 33.46" not a popular size so it might mean trouble if needing to replace one tire. Not sure it fits. Defender available
295/60/20 - 33.94" I don't know if it fits. Defender available
It's going to depend on the individuals priorities and any or all of these could be made to work.
A 285/55R20 is a no brainer drop in easy button size with nary any compromise.
Next up is a 295/55R20 which I personally think is the sweetest balanced size there, dimensionally almost par with recommended 285/70R17 factory recommended rock warrior fitment from the LC, but with a tad more width to take advantage of no KDSS interference, and to manage the heavier weights of the LX.

That guy was aired down to 20psi and was on 275/55R20 not 275/60R20, one inch smaller. Not sure if the taller sidewall would have helped, maybe there would have been more rubber to flex before pulling the bead.Besides the concern of short sidewalls which is legitimate, I would also caution running 275 tire widths on the stock 20x8.5" wheel.

I looked up Michelin spec for Defender 275/60R20 and the wheel range is 7.50-9.50". LX's 8.5 is right in the middle of the range. LX OEM size wheel is close to the Defender minimum wheel width (8") when in OEM tire size.
Just to clarify: I'm not debating wider tire is better on wider rims. I'm just trying to figure out the options for my particular use and tire availability.

I think that's a fair assessment and I would agree. Personally I have a hard time downsizing any dimension from factory and I believe there's advantages to running wider tire fitments.
for taller 275/65r20 is a popular size
If you don’t need an AT tire defenders are awesome. Even for an AT tire type of terrain they are. I would be running defenders as my summer tire now if they were available in the size I needed 2 months ago.
Quick question - new to me 2019 LC and put on some Falken Wildpeak ATs - 275-70-18 - what pressure do you all run this size tire at?
I finally got them on the highway and got up above 75MPH - they felt very unstable like balloons on the wheels in terms of jittery and bouncing around. I've noticed this at slower speeds on local rough roads - where it feels like its bouncing around over the potholes vs the older stock tires which didnt do that. I'll go check the PSI but they just came back from the tire shop and no TPMS warnings so assume they are close the recommended. Or would the recommended PSI change with the tire?
