20" tire options

So - I'm new to the 5gen models and just picked up a 2018 Limited with stock 20" wheels n tires. What is the widest y'all have used for tires with the 20" wheel and no rubbing? Looking to get these 'passenger' tires off of it. Thanks for any experience shared.

 

I'm running 265/60-20 KO2s. They were installed by the dealer when purchased new along with a front leveling lift (maybe 1" or so). Not my first choice. That said, there is a slight rub at full lock right in reverse on the left front inner fender liner. It's an easy fix that I just haven't done yet. The 265/60-20 KO2s have a recommender minimum rim width of 7.5" and it appears that the centers will wear prematurely. Plan is to go with 265/70-17s when the time comes. Ran them on my '13 Limited. Be sure to match the spare tire diameter to whatever tire you choose. Full time 4WD. All levels of stock 'Runners have the same diameter tires. Hope this helps.

 

I'm running 305/50R20's and they rub. I don't mind, love the look.
But if you want a wide-looking 20", I'd suggest 275/55R20's. They have roughly the same tire height but not as wide.

Don't forget too, rim selection has a lot to do with it. A rim that sticks out too much will cause the tire to rub when it normally wouldn't.
