2016 20'' Rim Specs

Could someone tell me the stock rim specs for a 2016 20'' rim. Some have said the offset is +44 others have said +31 with 5.97 backset? Im looking at a different rim that is 20x9 with +18 and 5.71 backset. I will putting on BFG KM3's 35x12.50R20 and I'm looking into how much clearance I will have. I will be adding a lift, I just dont know how much I need or if I can get away with nice leveling kit with UCA's with a diff drop.

Thanks

2106 2500HD Butte Red, 285/65/r20 BFG KO2

You can get away with a leveling kit on that set up or a 4-6" lift turned all the way down. personally i would do a 4-6" and turn it all the way down with no blocks in the rear to keep your ride quality.

I have a 2016 also and I was wondering if 35s will clear with Factory 20s. You can read some say yes some say no some say yes no cranking let me know how your outcome is . I had 2015 with 7.5 in lift and 35s. It road like silk I will admit but it was hard on the front end when I first had a level before the lift. If mine will hold 35s factory and no rub I would be tickled.

Your best bet is probably a 275/65r20 “34.1” on stock suspension.

Thanks Man yeah I already have it cranked a inch and haven’t seen any change but I have coppers maxx and they are chopped bad. Chevy says alignment is in spec but it pulls hard right. At 80k I think the front end is ready for parts. I run 50# air all around. I was thinking 35s but I know there hell on front end parts. Plus I don’t have a bumpsteer shock. I may upgrade the front end before I go with 35s! I’m ready for tires soon oh.

now my truck had been aligned before the switch.It ran nice and straight,even w/ a very slight back and forth movement on the front end steering parts.
after switch,throw truck on the rack,,believe it or not,all was good but an ever so slight toe out,some thing like .02 °.adjusted and it runs perfect on the highway,
running 60psi in all the tires.

So GMC502 you have 35s ? That looks good and I think you have me sold it works if that’s 35s. It looks so much better than those little tires. I had my doubts on the looks vs function, but my baby is just a horsepower and weekend pounder. It’s never pulled are been worked just drove. I have other trucks for that but I think I will go this route. I about have it how I want it with my cp3 conversion and built Trans and 200hp tune. This has been a wonderful lml and has performed flawlessly from day one compliant and non compliant. I think it’s just time for a front end rebuild unless my cooper Maxxs are just poorly made. They are loud and chopped and have been rotated every 5k and only have 25k on them.
