Largest tires on a tundra ,stock height

What are the biggest tires A/T that I can put on my 2018 stock height tundra 4x4

 

265/70-18

 

285/70-18 fit on stock wheels on stock truck with no other mods other than removing front air flaps under bumper. Thats a 34 tall tire.

 

I have stock 275/65/18. And if you have to remove the front plastic air dams for bigger tires I won’t .

 

then you can go to 275/70-18 without removing those air flaps, and this is with stock +60 offset wheels.

 

I like the brand Yokohama but the A/T thread does look aggressive enough I’m looking for a more aggressive threaded version , I don’t want to spend $300.00 per tire but I want a good tire. I will probably go with the Yokohama tire. 4 shells installed with an alignment 1000.00 buy Toyota. Is the good?
