2020 tundra “largest tire size”

I have a 2020 tundra crewmax 4x4 and currently have the nitto terra grapplers (275/55/20” wheel) I believe this is the size that came on the truck when new. When it is time to get new tires, I would like to go with something a little taller to fill out the wheel wells a little better. What is the largest tire I can fit that will not rub with a completely stock suspension? I was thinking the BFG A/T KO2’s in 275/65/20” wheel. Will these work without having the annoying rubbing when turning sharp or hitting my wheel wells over a large bump in the road? Thank you for your help!

Here is a thread that should help. In the first post it talks about the largest size one can run with different configurations, to include stock.

275/60/20

 

Some guys seem to have gotten away with 275/65r20 as well
