I'm talking about the "Auto Highbeam" push button on the turn signal stalk. I wish it was a "quick wipe" push button to activate the wipers once. I mean how often are people turning the auto-highbeams on or off? Either you leave this on or off. However I'm constantly having to twist the stalk end for the 1X wipe. Is there a way to re-map or switch/swap these buttons? It's quite often that reach for the push button hoping for a wipe. On my Ford, this is actually a wipe button. And there is no auto highbeam on/off button as it is an option in the settings.

Well they need to find a better way with some holding down button combinations or something. I can't imagine doing this in the winter in -40. Summer or winter, still seems like a waste of 5 minutes for this archaic method.

Wow you weren't kidding. I'd say it's gone up more than 5K. I was looking at ordering Denali Ultimate back in March but becUse of the chip shortage for supercruise they weren't taking any ordered for it. Then I found an AT4 that was already on its way to the dealership and it was the right color and fully loaded, so I got that and have been happy with it. Since I payed MSRP, I priced out the same vehicle again and it has jumped $10K

Is this the update that adds +20HP and +10mpg

Thanks! TIRES - 305/55R22 (35.2 inch tall by 12 inch wide)- Nitto Recon Grappler WHEELS - GMC 22 Inch Aluminum 5-Split-Spoke Wheel - Part# 84799395

Joining this thread.

did you get different ones? or are you going without the steps?

Picked up another set of wheels and 35in tires for the winter. These are Nitto Exo Grappler AWT that are Studded. Size: LT35X11.50X20 Although, the actual height is 34.5in as per Nitto's website, just like almost every other manufacturer who offers 35" tires. The wheels are 20" GMC Wheels. I wanted to go with 22in wheels again but there aren't that many options for 35in tires in 22in wheel size that are good in winter. Plus the extra sidewall is good for protection in the winter.

you can't go much bigger than factory tires, if you don't want to make modifications. AT4 has 32inch tires and denali has 32.8 inch tires. anything bigger than 33 wont fit. And there is an obvious visual difference between 33s and 35s. So if you want to fit half inch smaller tires (34.5inch) you're still going to need same amount of modification. 35 inch tires are usually all 34.5inch tires. However a 305/55R22 tire is actually 35.2inch tall.

I took these while I was installing the tires back few months ago. In the first picture, You can see how the mudflap looks WITHOUT the metal bracket, that used to be there. The aqua color indicates where I used the screws to secure the mudflap. I also trimmed the wheel liner, indicated by the red line. This is trial and error. Online you'll see some people just chop the plastic mudflap in half. I wanted to take out as little as possible. So after a few tries, this is what I ended up with. You can see in the first picture how it looks, it still looks like a mudflap and the bottom splash guard is still there. For the front, same thing. The plastic piece that I cut, is only used to hold the wheel liner in place. Again, online people just cut the whole thing is half, I just cut what needed to be cut. I used one original mounting area for the screw and then used a self tapping screw at the other mark. I did this a process a few times that day. I would modify and then put the tire on. I would check around and see what's rubbing when its on the ground. I also took it for a drive few times and make sure there were no rubs when turning or going over bumps when the suspension is compressed. Also I used this Milwaukee Oscillating tool

I think the infotainment takes like 5 minutes to fully shutdown. It stays in hibernation for bit, in case you're only making a short stop, then infotainment doesn't have to restart again.

Which sound system do you have? There's 6-Speaker Base system, 7-Speaker Bose Premium in AT4, 12-Speaker Bose Premium in AT4X and Denali. And I think Android Auto still uses Bluetooth for audio. I was under the impression that Connecting with AA would mean using Wifi for Audio which has higher bit-rate and better quality. But if I'm listening to music and I turn off wifi on my phone the music keeps playing in the truck.

I modified the wheel wells to get rid of the rubs.

Difference between the stock tires and 35" tires. Stock: 276 65R18 (32.1" tall and 10.8" wide) Vs GM 22": 305 55R22 (35.2" tall and 12" wide)

So, why did GM take this stance on tire size modification? People have fun with modifying their vehicles by putting larger or smaller tires on. Adjusting the speedo makes it safer for these people who did these mods.

just ordered a set a 35" Nitto Exo tires with studs. I bought different rims for this set as these tires/wheels will be for the winter. I'll post some pics when they arrive.

o wow didn't know this was being talked about. I'm in Canada and I have 35" Wheels on my refreshed AT4. I got told the same thing as you all. Dealers can only change tire sizes to the one the trucks can be optioned with. I'm out of luck since my tires are 35", the speedo is off by 10km when I'm going 100km. The only workaround visually I've found is running waze in android auto, as it shows GPS speed in the bottom right corner. Its small but its something. Kinda makes the heads up display useless, Even though I know that I'm going 10-15km faster than my speedo shows, psychologically it has me passing people and getting frustrated. I foresee some tickets in my future.

Is anyone else having an issue with receiving calls? I have Samsung S22 and when I receive a call, the call transfers to the Truck's infotainment and completely disappears from the phone. with other vehicles, the phone screen still displays the calling screen whereas with the GM, there is no call screen.

Thanks I'll try it out. that's too much work. There should be an easier way to restart the system. These refreshed models are still new so there's not a lot of documentation on these, but I'm guessing the technicians probably have a way for a quick restart of the system in their troubleshooting literature

Today, the infotainment screen was stuck on the GMC logo for hours. I shut the truck off and opened the door to shut off the infotainment but it kept starting up to the GMC logo, I did this few times. But I guess it takes a while for the infotainment to completely shut down. It probably goes into hibernation after the vehicle is shut off. I'm guessing this is so that it starts up quickly, unless the truck is shut off for longer period. I don't know how long that is. So wondering if there is a way to quickly restart the infotainment system by holding down some combination of buttons.

Maybe sport mode depends on engine option? I have a 2022 at4 refresh with 6.2 and no sport mode.

I actually like the little gurgle it makes when all the cylinders turn back on. And no the exhaust doesn't sound annoying at all and at highway speeds you can't really hear it much. I don't know if it'll be considerably louder with all 8 cylinders firing at that speed.

I really like these steps. They were part of the premium package I believe. I'm coming from auto-deploying steps on F150, and compared to those these are narrower.

Yea for sure. People give it a second look and ive been asked a few times what options those wheels are. Unfortunately GM doesn't offer 35s from factory.

It's titanium. Apparently I was the first guy to get that color it in western Canada. Glad it turned out to be a fantastic choice.
