What size tires can i put on toyota 20" rim limited model w/out a lift and will not rub?

Looking for a more aggressive look with the luxury package.... This is our first 4runner. We purchased it yesterday and we are absolutely in love with it.

2019 Limited Nightshade edition

BTW it is 4wd. Can't see it from this angle very well, but it does have auto running boards.

 

Beautiful truck! Congratulations.
Honestly, with those heavy 20" wheels, I would keep the factory size.
I am partial to the Wrangler Duratracs. No noise & all the capabilities!
Here is ours with Duratracs.

 

I love mine as well. Heres mine with a little twist.

Are you planning any mods?

 

I'm not planning on any yet... just the tires for now.

 

We went with Toyo open country. 275/55r20 They do fit but, we do get a very slight rub when we make a full turn in reverse while backing
out of our driveway. (emphasis on slight)

They look so much better than the OE.

 

On their tire retail website, Toyota lists 275/55/20 as an optional size tire for the Limited.
