Or you could just put on tires a half inch smaller (no visual difference) that actually fit and not have to hack up the truck and spend time trouble shooting. Granted you won't be able to say in a conversation (I have 35's) but you can always round up, seems much easier to me...

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 originally wanted the Denali Ultimate, but it wasn't available to order. Then I Ordered an AT4X, but it was going to take 4-5 months to build and deliver, but no guarantee. So I changed my order to

Looks good!  I opted for the GM catback and intake along with Grabber A/TX LT305/55R20.  Big weight penalty over factory for sure.  Massacres gas mileage.  Before 20-23 was no problem at 75.  Now luck

Not sure why you assume I want to say I have 35's in conversation? That would be like me assuming you leased your truck so you don't want to do any modifications. When in reality I just want the biggest tire that will fit without a lift and to me, 35's give it enough sidewall with the bigger wheels. Visually yes I can tell the half inch or so difference between the oem MT and AT tires.

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.

Met a guy at the dealership today, who was buying a similar truck as mine. He looked at my set up and wanted to replicate it on his AT4.

 

He priced out everything at the dealer and seems the costs have gone up. He got a quote that was almost $1000 higher than what I spent for the exact same parts.

@GM90 I was about to pull the trigger on 285/65/20 Mickey Thompson's on stock carbon pro wheels until I re-read your post. The diameter is approximately 34.6" and the width is 11.22", do you think these will rub on stock AT4 suspension? I'm like you, looking to fill the wheel well. Your truck looks great!

You won't have any issues with that size and stock suspension. I ended up going with nitto in the same size and they are slightly taller and wider then yours and I have no rubbing anywhere.

 

I originally wanted an overall size similar to the op 295/65-20 same height but slightly narrower. I got concerned if I decided to go with a level kit as the new control arms can limit tire size. The 285's on mine are very close to the stock control arm so I'm not sure the 295's would've even worked with the stock suspension without a wheel spacer. I'm thinking it may be because the op has 22" wheels.

That's great news, thank you for confirming. Do you have any pictures? I'd love to see your set up.

I originally wanted the Denali Ultimate, but it wasn't available to order. Then I Ordered an AT4X, but it was going to take 4-5 months to build and deliver, but no guarantee. So I changed my order to a fully loaded AT4 that was dealer ordered with the engine and color I wanted. So I was able to get it in a month. I was planning on changing the rear bumper on the AT4X to the one from AT4, so I could have exhaust with quad tips. I realized that I didn't really need the AT4X  because the main difference is the lockers and suspension, as I wouldn't take it rock crawling or serious off-roading for the departure angles to matter. 

 

 

 

Engine - 6.2l (Read somewhere that GM has stopped the production of the 6.2L V8 Engines until next year or possibly longer. Lucky to have mine, just before the announcement) 

TIRES - 305/55R22 (35.2inch tall by 12 inch wide)- Nitto Recon Grappler Tires

WHEELS - GMC 22 Inch Aluminum 5-Split-Spoke Wheel - Part# 84799395

EXHAUST - BORLA S-Type with Quad Exhaust tips - Part# 140774BC

My next upgrade is adding the GMC kicker subwoofer to the truck.

 

 

Truck exhaust sounds really good! So glad I went with that exhaust. No drone, Quad tips look better than the HDMI exhaust tips.

 

Wheel and tires are actually smidge taller than 35inch. Toyo Open Country 35X12.5X22 are actually 34.5 inch tall, they have an easier time fitting than these Nitto Recon Grapplers. 

 

The weight of the Stock 275/65R18 tires and wheels was 80lbs.

The weight of the new 305/55R22 tires with 22inch GMC wheels are about 106lbs.

Difference of 27lbs extra per wheel. Which isn't as bad as I thought it would be.

Nice comparison, those 35's make the stock look like bicycle tires.

No level, 285/75-20 Nitto Ridge Grapplers. Like I said I really wanted the 295/65-20 but I'm undecided on a level. Most of the time I'm happy with it stock and it still rides pretty good, but there are times where I wish I had a level cause it looks good.PXL_20221107_221129671.thumb.jpg.948df44b5fa7176fbffac8e00c90f7ad.jpg

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      2027 GMC Sierra: Official Discussion

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.
