For me it's hard to know what a minimum tire size will need to be until we have more information on how heavy it is and what it takes to fit larger ones. Visually it looks like 35's are a bolt on size. Especially side by side with the LC300 - the wheel wells are much larger on the LC250. And with the larger footprint it may need bigger tires on a lot of trails than you might fit through with a 4Runner on 33's. And you'll need 35's to match the ground clearance of a 4Runner on 33's. I think I'd go with 35s if they fit, and 1.5-2ish inch lift with improved shocks, sliders, skids, and a winch in either partial bumper or hidden winch mount. Not sure what shocks I'd look for. I liked the ride of Fox Factory Series on my 4R, but didn't like the annual need to pull them out and replace the bearings. I did like the ability to open up and adjust valving, but my life doesn't have enough free time right now to spend weekends re-valving shocks. Ideally if a set of Tundra TRD Pro shocks fit - I'd find a set. If not, I'm not sure what I'd choose. I'm not sure I'll ever buy shocks for a daily driver again that have spherical bearings.
For me, that would get me everywhere I'd want to go before I'd either take my FJ40 or SXS for the more challenging (damaging) trails. Just like I had my 5th gen 4Runner setup. And still hopefully have great highway ride/handling. If I buy one - that's probably my formula. Keep weight to a minimum with no bloat. Just the minimum necessary weight. For me the winch, armor, and bigger tires are all probably must-haves. I sure hope the transmission shift logic can learn how to play well with 35's.
