2022 2500 HD Duramax wheel change issue?

[Eric Nys]

Hello - I'm new here trying to find out info on Why I can't upgrade my wheels on newly purchased 2022 HD Truck. I'm still waiting on truck to be delivered. It is coming with standard 17" wheels. I said what the hell -let me upgrade to the 20" black rims and make it look a bit beefier. The salesman are telling me I cant because of some calibration stuff or whatever. Does anyone know what's going on that can explain it to me so I get it ? I like the 20" because another hd gas model I was going to buy , that fell through had them on it . I liked the look. On another note Do I need the 20" is 17" fine ( I feel they are too small and just basic - wanted to black it out emblems, step bar ,wheels) or would 18 " be better - Not sure what the difference is on terms of ride etc. Thanks for any help.

The accessory team sells a 20 in tire kit to upgrade trucks.  It could still be on stop order on trucks equipped with 17" tires due to a recall in 2021.  The issue is if the truck was originally equipped with 17's and you install 20's, you need to change to 18" spare.  Otherwise, if you install a spare on rear axle the locking differential could not unlock due to the speed delta across the axle.

Thank you . Do you know what the 20" upgrade kit is called or a part number ? Dealer really has no clue or is just being lazy.

Salesman are not always the most informed people to deal with. I know at my dealer they are mostly all younger people and hardly know anything about the vehicles they are selling.   I would check with a knowledgeable parts person, if that dealer has one.

GM has authorized calibrations that are performed to flash the truck to these.

 

You will need to also order a new spare wheel and tire to go with any of these that GM offers.

I'd just leave it and throw an aftermarket setup on after you get it.  Alot of options that way and you can always sell the stock one's to help on cost if you need to.
