Any advantage to going with 255/70/17 vs stock 265/65/17 with Sema Pro wheels and Cooper At3 tires

I've been looking and reading for the last 2 days on the forum and decided finally just to ask my specific questions. I have a 2016 trd Sport Stock with the 265/65/17 stock Firestone Destination LE road tires on the 2015 Sema Pro wheels. I want to go to something a little more aggressive and am going to go with the Cooper AT3's. Is there any advantage to going with the 255/70/17 over just getting the stock 265/65/17? The sema wheel is only a 7 inch wheel which is what got me thinking about going with a 255. But they seem to be very close to the same size wheel when I use the tire size calculator. I do not off road, other then camp roads sometimes. My number one concern is rubbing, I don't want any rubbing even at full lock. I know the more aggressive tire even at the stock size could have more potential to rub due to the tread and sidewall pattern. Then I was wondering about better fitment with the 255 on the 7 inch Sema wheel and if there was any advantage for city/highway driving. Any insight would be very helpful. Here is the current pic of the vehicle.

I run 265/70/17 Nitto G2 tire on those wheels and don't rub at full lock on stock suspension so you're not going to rub at a 255 tire.



I do have a OR with no airdam or mudflaps either with a plus 1 size but you should be fine.

 

What did you end up going with? I'm looking at 265/70r17.

 

What's your mpg look like?

 

Usually I average about 20-21 mpgs per tank but also have sliders and a toolbox full of stuff so theres extra weight to consider.

I also keep it below 70mph on the highway.

 

OP, any update?
