What is the largest tire one can run on the factory 18's without rubbing or adding any lift? Should be picking up a new 2019 soon and I'd like to replace the stock rubber with KO2's or Toyo RT's on the factory wheels for the time being. Thanks for any help.

Zero rubbing on my LT285/65R18 KO2s, though it is very very close. Stock height rear.. front does have the 10mm spacer but all other suspension parts/geometry are stock.
BUT: 285/65 is only available in an e-rated LT tire which requires 42psi minimum on our trucks. This has a very significant impact on ride quality. Frankly, I hate the ride and have considered going back to stock size KO2s for that reason alone. Whenever I wear these out I will. For now it's not worth buying all new tires.

Thats very odd to me.
The very first thing I did on my 200 was add E-rated KO2s (285/70/17 on rock warriors) at the same psi and the ride was certainly not worsened. I did not have strut spacers though, which extend your CVs downward. Curious if that may be the change in feel for you...? I don’t know. I just know my e-rated KO2s rode just fine.

I run E-rated 275's on our 2018 TRD Pro 4Runner with a 1.5" lift and I don't think it degrades the ride over stock all that much but if you spend any time on the 4Runner forums you'll hear lots of complaints from the peanut gallery. I think they have a valid argument, but in no way would I call the ride horrible or unacceptable. Maybe the same could be said for the 200 on E-rated tires?
i have a set of michelin ltx at2 e rated tires in the above mentioned size in on the factory 18" wheels. I put them on before the spacer install which has absolutely zero impact on ride quality. The difference in e rated tires and factory though is pretty significant. Ride is much firmer. Not horrible but definitely more truck like and will experience some sideways hop on the interstate if you are going around a turn at 80 and hit a pothole. I also have a set of cooper stt pro's on rock warriors. same physical size but 17" wheel. 285-70-17 vs 285-65-18. The 17's actually ride a little softer but not sure if thats brand or what. They (the coopers) are loud as hell though, but they are a full blown mud tire.
That being said i drive 100 miles a day and dont find the e rated tires a deal breaker, but only because I understand the trade offs. They definitely take the luxury out of the ride of the truck.

To be clear I don’t think it is the fact that they are e-rated, as IIRC any LT-metric tire would need to be in the same tire pressure range. I suspect it is primarily an issue of tire pressure, maybe made worse by AT/LT/E-rated tire weight.
Either way, even with brand new OE shocks these things will shudder and send significant vibrations through the chassis over sharp bumps, even making the headlights shake. The stock p-metrics didn’t seem to do that.
Higher end dampers would probably help the situation as I’m sure the stock ones were tuned for stock tire pressures and weight ranges..
That’s my point. And with how I use this truck.. thousands and thousands of road miles to get to jeep roads for camping or whatever.. I didn’t like the trade-off.
I’d be VERY interested in a 285/65/18 p-metric but I doubt the market is there
Edit: now that my cruiser isn’t saddled with daily driver duty the ride will probably annoy me a lot less. But knowing what I do if I had to daily this thing I wouldn’t put a tire that requires 40+ psi on it again.

I am not a fan of e-rated tires. Every time I get them I remember why I didn’t like them. Tires are definitely personal preference though. For me the best tire on a 200 is a D rated. Still can be deflated for off road and not as “heavy” feeling as a E. On my old ‘13 I loved the KO2 34/10.5-17 but just wished it was 1/2”-3/4” wider. But rode so much better than the e rated tires I had on before and after them.
For my ‘19 since I have the BBS wheels in 18” I’m still deciding which size to do. Problem is there is very little support on who makes D rated tires. You can get stock size KO2 or 285/65-18 in Duratracs which I’m not sold on but may just end up with due to their D load.

I think the e rated Ko2 definitely changes the ride quality if you like a squishy ride you are not going to get those with these tires. It will form up the ride, but hey your getting an e rated all terrain tire. If you want a great ride I would suggest getting some Michelin highway tires. If you want good off road, reasonable on road and snow performance I would go the KO2... on the road I think Ko2 are nicer than duratrac...

Just a word about tire pressures:
For the LT285/65R18/E 125/122R Load Range E KO2's the Recommended Cold Tire Inflation Pressure is indeed 42psi on the LC200.
For the LT285/60R18/D 118/115S Load Range D KO2's the Recommended Cold Tire Inflation Pressure is 46psi on the LC200.
So... you may think you are going to get a softer ride with a D-Rated tire, but with an increase in tire pressure and less sidewall height you may actually wind up with a rougher ride.
Food for thought.

Take my word, stay away from the DuraCraps. The KO2 is five times the tire.
Anecdotal story since I don't have time to find my sources at the moment.
When Ford was developing the Raptor, BFG only had K02's in Load Range D and higher. Ford, being a large enough customer, sent the BFG engineers back to develop a LR C variant on account of the ride quality being too rough.
In the aftermarket, you'll rarely find anything but LR E, to simplify their distribution and line-up, and because consumers are not discerning enough except for "more better".
When it comes to ride, sidewall compliance vs load range generally follows from better to worse ride P < XL < LR low to high. Compliance also varies between tire models and manufacturers.
I know @gaijin follows a strict loading interpretation for his tire pressure recommendations. While a very important criteria especially when laden, I'll say it's not the only criteria and perspective. There is leeway to tailor for ride and handling as needed.

The LT 285/65-18 K02 is a big, heavy tire. It is significantly heavier than a stock size highway tire. Adding unsprung weight isn’t good for the ride.
If you are looking for the best ride, stick with the stock size and get a comfy highway tire like the Michelin LTX MS/2.

I need something with more traction and durability than the stock rubber, hence why I am asking the question in the first place. The stock meats are great for running up and down the highway and city streets, but this will see use at the ranch, the farm, and the beach, I need better tires for those applications. The ride while important, isn't the main focus here, if I were concerned with that above all else I wouldn't be buying a Land Cruiser to begin with.
With that further information, I recommend the Michelin Defender LTX in the stock size, LR XL: 285/60R18 120H XL. It's a nice tire for the uses you have listed and will be comfortable too. And FAR better than the OEM tires.

Might need to replace your springs/coil overs.
My stock suspension was generally horrible when the truck was 5 years old. Bounce and shudder changed dramatically after a full suspension upgrade.....same 285/70/17 E—Rated KO2s...But a completely different ride with no shudder, bounce, etc.
I like my Nitto Terra Grapplers G2 in stock size. Mine are not a LT tire but they do offer a LT version in the same stock size. Very little noise at 55mph and none at 70mph. They are more of an AT tire and more aggressive then the Michelin LTX. The Terra Grappler is also available in a non-LT version of 305/60/18 with a 32.4" diameter which is slightly less than the 32.56" diameter of the 285/75/18. However the 305's might rub without spacers.

I am running the Toyo RT's and am very happy with them on the LC200. I run the toyo MT's on my Jeep and RAM diesel.
I did stay with the OEM size so I wouldn't run into rubbing at compression while turning. I do not know the max size possible but I do know actual tire size varies from manufacture to manufacture. There's a spec sheep on toyo which is accurate for the real tire size.

While I know you have other application, I can tell you that stock will do fine for beach - in fact, the balder the better
- it's all about airing down.
