I thought i would post this to help anyone looking for rims and tires i had a hard time finding anything on this truck . Heres my 2019 gmc sierra at4 with 4p08 4play rims with 33x12.50x22 we had to level the truck and add a 1/4 inch spacer to bring rim out off caliper and some triming had to be done on the mud flaps so it didnt rub but wow what ya think .

Stock suspension, stock wheels painted Piano Black, Nfab RKR steps (rock sliders) General Grabber AT's 285-60-20 . The stock running boards are way too thin and bend when they get bumped. The tires are quiet, didn't change my gas mileage and look a lot better than the Bridgestones .

Looks awesome! How do they fit? Any rib? I'm planning on the 285/60/20s in ridge grappler and new rims with a -24 offset

No rubbing whatsoever. I would seriously consider the General Grabber ..they are rated for snow and are super quiet on the road. I've had both and like the General's MUCH better!!

How’s the performance after those tires? Very interested in that size but the Grabber, similar to others, comes in at 62.6lbs. The stock Bridgestone tires on the 20” are 46lbs.

There isnt a 4 inch lift out yet for the AT4/Trailboss.  The only lift out adds 4 inches to them making them a full 6 inch lift

I believe they are heavier, i through them in the truck when i got them.... They are a 10 ply tire too, so a lot tougher. The Grabber AT is probably the best tire I've used to date. I've had KO2s and Ridge Grapplers, these are quiet, tough and reasonably priced. In Oregon it was important to have a tire that's good in the sand, snow and highway. The Bridgstones are not bad tires i just didn't like the look.

Yes thats the lift i was referring to. Fabtech calls it a 4'' but its the same as a 6 inch on a regular sierra.

New guy here...been watching this forum unfold while I’ve been doing research for Lifts/Wheels/Tires and Running boards for my new Black AT4. I need some suggestions for wheels (black preference, like matte more than gloss, and not a huge fan of the chrome beads surrounding the outside of wheels). I’m getting my truck project started next week and doing the following: 4” Rough Country Suspension Lift (made for the AT4), Nitto Ridge Grapplers in either 295/65/20 (35.12x11.77x20) or 35x12.5x20 size, new wheels in either 20x9 or 20x10 (still trying to decide on the brand and style), and then the amp-research power running boards. Here’s a picture of what the truck looks like now. Only mods so far are a Bakflip 2 MX trifold cover, and Ceramic Lumineer window tint (20% on all windows, and 35% on front windshield). The stock wheels are 275/60/20 (can’t find what the stock offset on these are though). Any thoughts/suggestions or comments please let me know! Thanks! And hurry cause this project is starting next Thursday!

Is there any way to recalibrate the speedo yet?
