RE Tire size; I just painted the OE wheels Piano Black and installed General Grabber A/Ts 285/60/20 For me they are the perfect balance of an aggressive tire and great tire on the road. As a side note

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.

A little off topic but has anyone got any 4 inch lifts installed on there AT4 yet? 

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!

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
