How do I get my Tahoe to ride/handle like my 3500HD?

Inflate your tires to 50 psi..... LOL!

I feel like just lower profile tires on larger wheels will accomplish much of this, but couldn't say whether 20" would be enough or need to go to 22"

NOPE

NOPE

BECAUSE?

BECAUSE?

the lean and sway is from the suspension at standard height the widest tire you will most likely fit is a 305 that will still rub at full lock and will do practially nothing as far as handling
you "might" get a little better grip (accelerating/braking) depending on the tire, wider tires are heavier, might cause less response, they are less efficient and can cause oversteer and might actually feel less stable in sharp turns

BECAUSE?

They will make your truck ride rougher no doubt, due to the reduced sidewall height, but it may actually handle worse. Tire choice is probably more important than rim size.

Installing General UHP 305/45/22 tires took the handling of my 2018 Yukon Denali to the next level especially in sharp turns. I have plenty of curvy hilly backroads to play on. Response & grip are very impressive.
For clearance I adjusted the fender liner mounting tabs so I don't rub even with a 2" spindle drop in front.

the right tires of course can make some difference, but tires alone will not fix sway and lean, there is a significant difference in suspension with your denali and a z71, particularly being lowered as well. those particular tires would probably be too soft for me. How is the road noise now compared to when they were new?, usually with soft tires after about 10k miles the road noise increases a lot

Tires are pretty quiet now but I only have 5K miles on them. With the Hellwig swaybars + lowered + 305/45/22 summer tires it's not Cadillac smooth but smooth enough. I can hit those curves hard without any body lean. Upgraded cam (no AFM) & tune is icing on top. The bigger tires did cost some mpg but after syncing my speedo to a GPS I'm at 21.7mpg for the last 4,000 miles of mixed driving, drive thru, & sitting idle.

Oh, duh, OP should just go test drive a Tahoe with 22" rims...
