Yes, this was confirmed by GM multiple times and I'm pretty sure this is even mentioned on the website. Anyone saying the previous 6x120 bolt pattern is being carried over is incorrect.

welcome to the forum, where is "some places"

GM has confirmed, so do not go looking else where

 

Multiple dealers for wheels (tire rack and rimzone) as well as 2 GMC Dealers... but they seemed unsure. I tried going through GMC website but they referred me to dealers... who obviously gave me wrong info.

Does anyone have any links to these videos/discussions where it is mentioned/confirmed by GM?

 

Our data is indicating 6-139.7 as well, though we do not have complete O.E. wheel dimensions or stud size as of yet. I would imagine the lug hardware will remain 14x1.5, however the 1st gen did have 12x1.5.

 

Great, thank you!

 

Happy to help! When we learn more we'll be sure to share.

 

Any chance you have an idea of what the offset is?

I'm trying to see if I can run. A 285/70r17 on a -12mm offset.

My AT4 is coming with 275/60r20 (which is gross) so I think it's doable depending on offset.

 

They're the same as Silverado so expect the stock offset to be +26 for 18" and +28 for 20"
