19-22 GMC Sierra 4x4 lowered max tire size?

[Duanel21]

I’m looking to lower my 2020 GMC sierra 1500 4 x 4 2/4 belltech possibly….I’m wanting to put the largest tire I can put on my factory 22s after it’s lowered with no rubbing issues.TIA

I've run roughly 31.5-32in tall tires on several 1.5/3 and 2/4 drop trucks. If anything, they only rubbed at full lock and hitting a bump at the same time.

 

285/45/22's is what I'd probably run. I was running 275/55/20's on a truck with no issues and that's within ~.1 of the 285's.

Did you ever end up lowering the truck? Would love to see how it turned out.
