I saw exactly the same thing, but decided to go with the 255/80R17 E load. Here's the catch (at least for me) - I kept my 20" OEM wheels. So, I'll mostly run the E-load tires when I take my LC off-road. The more durable sidewall will definitely be a plus when I'm climbing on a trail in the mountains. I'll eventually replace the OEM Geolanders with something that looks and performs better as a daily driver. I'm pretty certain the 285/70R17 will fit with no rubbing, especially if you aren't off roading it.I really wish there was an SL rates tire in the 255/80r17 size. I personally will not use an LT tire, especially not an E rated tire. Like most of us, the majority of my driving is on the road and 10-ply E rating is much stiffer and less compliant compared to passenger tires. In my opinion it only makes sense for a dedicated rock crawler or extremely heavy trucks, much heavier than our LCs.
This leaves the only two decent options at 33”, 275/70r18 and 285/70r17. I’m really debating these two. If there was a higher offset 17” wheel I’d probably go with that. I think there would still be some poke on the +35 offset 17” wheels with the 285s on the 1958, and I’m worried it will result in flinging things at the paint. Also probably compromises scrub radius too much. Leaning towards an 18” and only really prefer 17 for the aesthetics.
I don't find my E-load WildPeak AT4Ws to be excessively harsh in comparison to the 20" OEM tires. But, occasionally we hit a pothole or bump on the highway and it's definitely noticeable.
