Thanks again.The tires on the 2021 Silverado are 265-65-18", which was the original size tire in 2016 if the truck had had 18" rims installed when new. I think the speedometer is within 0.1% between the two sizes. I'll ask the GM dealer tech to reset the computer if he feels it is necessary.I think both of those generations use 25mm offset as the primary offset. There are guys on this forum that run 275-65-20 (34.07") with and without a level. Some trimming and no trimming. 275-70-18 (33.16") should work, 265-70-18 (32.61") will definitely work.
Do you have any pictures with your set up? I’m looking at getting 2021 Denali takeoffs and putting them on my 2016You’ll need to post more specific details about what style wheel you’re looking at. But overall. They’re all pretty much interchangeable unless you have the big brake mod
I have 2021 Tahoe wheels on my 15 Yukon with no problems
I don’t take many pics of my truck but these are 21 wheels on my 15. They aren’t oem they’re aftermarket but should share the exact specs of the oem wheelsDo you have any pictures with your set up? I’m looking at getting 2021 Denali takeoffs and putting them on my 2016
