I have 285/65/20's on my 19 AT4. I pulled in really fast into my driveway at an odd angle once and it rubbed. Other than that, no problems at all.

Thanks for the info.

Hi all, I'm putting some caliper covers on my 19 AT4 and have to get 1/2" wheel spacers for clearance. They are just a ring type you slide on the hub. Of course I'm losing a half inch of lug in the process. Has anyone been down this road before? I'm a bit worried about how much lug length I'm losing. I feel that if I get 7 or 8 turns on the lug nuts I should be fine. Thoughts?

I will. I'm at work ATM will post some when I get home. They are the Falken Wildpeak AT/3's.

Anyway, if I felt this size was not a good idea because they rubbed enough to mention I would say "no ,they won't fit." If you want to not get this tire size because I had a slight rub one out of 50x pulling into my driveway too fast then you go right ahead. That's why I noted it.

Ok, so I ordered 1/2" spacers strictly for clearance to put caliper covers on my 19 Sierra AT4. Wasn't planning on any stud trimming etc. Anyone know if this is going to be an issue for me guys?

Ordered, installed about a month ago....they rubbed one time in full lock hitting a driveway at an angle. So, yes, they fit. thanks for the answers guys.

4banger, I did go the guinea pig route. Yes, they bolted right up to the same holes the old ones were, except they only use 3 bolt holes apiece instead of 4. They fit a '19 100%.

So, I have a set of these ordered for my 2019 AT4. Will let everyone know how it goes.

Ok so if anyone reads this my question has been answered. They do fit. I have a pair on my 2019 Sierra AT4. Bolted up no problem.

This gentleman says he’s put a 285/65/20 set on his AT4. Stock. No rubbing. Haven’t seen anyone else put on this size tire. Can anyone confirm this?? I’m about to pull the trigger on a set for my ‘19 AT4 if so.

Ok, so according to this gentleman he has 285/65/20s on his truck. All stock. No rubbing. I've heard from several people this won't work. I think it will and am willing to fix any slight rubbing issues...as long as they are slight. I plan on putting a leveling kit on as well which may help. Going on a 19 Sierra AT4. Has anyone been down this road guys?

Definitely looks better. Good job. Don't sell yourself short...it's a mod!

Hi guys, how about just posting some pics of your Sierra? Maybe a small breakdown of what you've done to it as well. I just got mine and I'd love to see some different ideas. Especially the wheels and tires. I want to upgrade mine but there are too many to add/rule out unless I see them on one. So, show them off!

Thanks for the info guys. I think the collective thought in the thread is that there's no reason why they shouldn't. I will most likely get a set but be on the lookout to score some a little cheaper.

Don't know what color yours is. I own a black 19 Sierra AT4. Depending on how much you want to spend, you could always 1) upgrade the wheels/tires. That's where you'll get the most change in looks. 2) You could also Hyperdip the badges black (or wheels for that matter). 3) Grille inserts are relatively cheap and drastically change the front end looks 4) If you have the money, there are plenty of exhaust systems out there. Borla's are nice (but not cheap) 5) Tonneau covers 6) new Running boards as well 7) last but not least take a sledgehammer to a rocker panel. Definitely does something to the looks. My least favorite though.

Haha @ CamGTP...not just a no, a Hell no!

I don't either. They are pretty sharp looking IMO I'm surprised nobody has tried this before. $1k is hard to drop on a chance (however slight) they won't work. Thanks for the reply.

Hi guys. I own a 2019 Sierra AT4. My dilemma is the optional factory 'assist steps' (#84630474) I've seen on AT4's later than mine...mostly on 21's and above. Pretty sure I've seen them on a 2020 AT4 as well. Will they fit a '19? Everywhere I ask people tell me they're "pretty sure" they'll fit but I'd like to know for certain as most places offer no refund, so I'd be stuck with them. Some fitment charts say they won't fit. My guess is that they do, but weren't even an option until 2020 and kicking me a "won't fit" because of this. Much appreciation in advance.
