285/55r22’s on leveled Denali

[Natea275]

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.

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

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.

This gives you an idea of the clearances with the above listed modifications. Please excuse the salt residue from our wonderful DOT team.

Thank you for the reply.

 

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

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…..
