Biggest tire with 5100’s on top setting ?

Hey guys and gals,

I’m in Afghanistan and my internet has been ungodly slow so searching the stance thread i haven’t been able to make it thru all the pages to try and find this answer, I was hoping some of y’all could help me out.

I have a 2016 crewmax limited with 5100s on the top setting up front and stock rear. I would like to put the tallest and widest tire combo onmy factory limited wheels and preferably space them out 1.25”

What is the biggest I can go with minimal trimming and what looks better?

I’m thinking 295/60r20 or 285/65 is probably my limit... can anyone share insight and pics ?

Will the spacers cause issues with clearing this size tire ?

And lastly what’s your thoughts on th the ridge grapplers as far as noise and
