Leveled 2017 Denali 2500 - wheel and tire sizing help

[LiquidSn4ake]

I’ve spent countless hours browsing the custom offsets site, but haven’t had luck coming up with a definitive answer on an appropriate wheel and tire size combination for my leveled 2017 2500.  So, I’m looking for help from the experts here!

 

Here’s the important info:

 

2017 GMC Sierra 2500HD Denali

current stock rims & tires - 265/60R20

ReadyLIFT 2.25" FRONT LEVELING KIT W/ HEAVY-DUTY FAB CONTROL ARMS

Bushwacker Pocket Style Fender Flares

 

I’d like to go with the largest wheel and tire combo that will fill the wheel wells without rubbing/scrubbing and move the tire stance out enough to match the width added by the fender flares.

 

I’ve been looking at a few different models of 20” Fuel wheels and the following tires - BF Goodrich KO2, Toyo Open Country AT II, or Nitto Ridge Grappler

 

The local shop is very conservative and won’t discuss anything over 295/55R20...

 

Thoughts, comments, recommendations?

 

Thanks in advance!

Not sure about with after market wheels, but on my stock HC wheels I put 295/60/20 Toyo Open Country ATII with no rubbing. Im running the cognito leveling kit with UCAs.
