I know this gets asked all the time, but I’ve searched and searched and came across conflicting information and just want to confirm before purchasing. 
 

I have a 2023 Denali ultimate with a 2” cognito level installed. 
 

Will 285/55r22 Toyo AT3’s fit without rubbing?

 

Factory wheels, +28 offset. Factory UCA’s. Tire spec’d to 34.4”. 
 

any insight would be much appreciated.

The 285/55r22 Toyo AT3's should generally fit well with the specified tire diameter of 34.4 inches.

However, a couple of additional considerations are in order. Confirm that your wheel wells have enough clearance, especially when turning, and check for any potential interference points. Also, keep in mind that individual variations in vehicles due to manufacturing tolerances can sometimes result in different outcomes.

Ok, thanks. I will keep it in mind.

Possibly.  There are some differences between the Chevy and GMC trucks that could cause issues, especially with the fenders and wheel wells.  I'm running 285/75r18 (34.8" calculated, 35.1" per the manufacturer) on my 2020 Trail Boss without a lift/level.  The Trail Boss has a 2" lift from the factory, so it would be on par with a Denali Ultimate that adds a 2" lift.  I did have slight rubbing at full lock and ended up removing the mud flaps.  Even after that I still had the slightest rub with a wheel well liner that went away as the tires wore.

Didn’t you just get all up in my grill about posting in a forum where the op asked about a Chevy truck and here I find you posting your opinion on a gmc truck. Should I go on about your comments being garbage?

Let me preface by saying I do not have a Denali. I have a 22 SLT that I installed an AT4 lift onto. I placed 1/2” pucks on the front essentially giving me 2.5” of lift in the front and 2” of lift in the rear. I also installed Rough Country UCAs. onto the truck do to the fear of factory UCA catastrophic failure. Along with the lift I used hub and wheel centric billet 1/2” spacers……. Wheel studs are from an early 2000s super duty….. yes they fit. Front replacements are Dorman 610-530 M14-1.50 Serrated Wheel Stud - 15.90mm Knurl, 78mm Length, Rear replacements are Dorman 610-490 M14-1.5 Serrated Wheel Stud - 15.7mm Knurl, 69.75mm Length. These front and rear replacement wheel studs are just under 5/8” longer than stock studs. This allows you to have the same thread engagement with the lug nuts as stock. As well as the lift and wheel spacers I had to trim the front fender well.

Here is the write up I used for trimming. 

https://wheelsasap.com/gmc-at4-oversized-tire-trimming-guide/

 

My tires are 275/65R20 Nitto Recon Grappler. Overall diameter is 34.09” and Overall width is 10.98”.

 

My tires are 3/10 of an inch shorter and 3/10 of an inch narrower than what you are looking at doing. I had to do all of the above to fit my tire without rubbing. The stock 20” SLT wheels and the Denali Ultimate 22” wheels have the same backspacing and offsets.

Thank you for the reply.

 

I was under the impression that using spacers would actually cause more rubbing.

How do you like the level kit? Works with arc?

Well it certainly looks better if you ask me. It'll look a lot better when I can get some A/T's on there.

 

Ride doesn't feel any different to me. Slight change with visibility looking over the hood.

 

No problems with ARC or Super Cruise yet.

Yep, sure did.  Not just you, but the other guy, too.  I called you both out for e-fighting.  I was hesitant to even make my post here because of that.  Nonetheless, I made the post.  Unfortunately, it's evident your apology in that thread and the linked post were insincere.

 I did concede to not know about Silverados and my apologies to you were sincere at the time. I believe if you read the post you stated my posts were garbage because I was a gmc owner. The exchange between myself and trueblue had nothing to do with you and you chose to insert yourself into it. Yes I did point out you are not a gmc owner here and as you did in the other thread to me. I am sorry.

The problem with going with a wider tire and not using spacers is UCA clearance.

1/2” spacers is ideal…… but if you do not used the longer studs you lose thread engagement and this become dangerous…..

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
