New LC300’s come on 265 aspect tires. As does the new Sequoia. Lots of half ton pickups come on 245 and 265 aspect tires. I don’t believe, at all, that wide tires are needed on a 200 for anything on road. Hard cornering isn’t what the vehicle was made for, or what it’s good at.
As far as off road, I’m far less experienced than many on this forum as to wide vs skinny, although what I have read online points to skinny being better in most situations.
You are quite knowledgeable about our vehicles and I have learned from your posts on a variety of topics. But with regards to wide tires, it seems as if you are reaching for theoretical reasons why wide is better, versus admitting you just like wide tires.
