How wide and recommendations

Got my new '21 off road yesterday and first thing is tires. Now, I don't want to lift it currently, but I do want to change the tires. Question is how wide can I go without changing the stock rims? Can I go with a P275/70R17, which is a bit wider than the stock P265? Will a tire like that rub without a lift?

Also, BFG KO2 or Wildpeak AT3W?

 

If you don't lift you can go 275/70R17 with TRD ORP but its pretty close fit. Something to note that I could not find any P275/70R17 A/T tires. All I see is LT275/70R17. I've used BFG KO2 LT275/70R17 but they only have Load E and I didn't like the firm ride. Falken Wildpeaks have 275s in Load C. Sadly no Passenger rated tires with that size as far as I can see.

 

Well, what rim do you have?
