Larger tires on 2025 AT4 Ultimate

[Donnation]

I was wanting to put some more aggressive tires on my 2025 AT4 Ultimate. Can anyone guide me here on how large they can be without a lift? I’m looking for something like Nito Grapplers to be put on them. Thanks!!

I feel like there's a million posts on/about this here (and it's just a shame that all the info isn't in one, pinned thread)...

First question everyone will ask is whether you have air suspension, followed by how wide of a tire you want, followed by whether you're willing to deal with ANY rubbing, or whether you're at least willing to do the pulled-back-liner mod.

Oh my apologies. I couldn’t find anything related to a 2025 (if that even matters). I was just wanting some larger tires like 285/55/R22 Ridge Grapplers. Just wondering if those would work without having to do any extra modifications.

No apology necessary (or maybe I owe you one, as I wasn't trying to be dismissive). Maybe the real [first] question is whether the suspension has changed on the '25s such that there's more clearance around the tires, but I haven't heard anything like that. Until someone can definitively say that the suspension has changed, then I believe you can go off the '21-'24 info available here.

Donnation -- Def sniff around the Street Suspension and the Lifted Suspension forums. Lots of people have asked what size tires (including the ones you're looking to put on your truck) they can get away with in those two forums. And if a lift or any mods are required, you'll get that info there, too.

If you go to https://www.customwheeloffset.com and put in your vehicle or search their site for fitment….but better yet you can see their ‘customer builds’ where people have installed oversized wheels/tires and submitted pictures along with details of any suspension mods / thrumming needed if any. Really good info!

Was able to fit 275/65 on my 2025 with no lift. No rubbing at all. The tires come out to be like 34.1" x 11".
These are the Toyo R/T Trails.

Here’s my journey. I bet 1,000,000,000 internets nothing with the suspension geometry, height or wheel offset has changed from the 2024 AT4 to the 2025 AT4.

285/60R20 BFG AT KO2’s on my Yukon AT4: fit remarks

I did a lot of research to see what was needed to mount these tires on my stock 20” rims, on my Yukon XL AT4 (air suspension). I did use the Westcott Designs fender liner pullback kit with great success as there’s no rubbing at the rear of the fender liner after doing the mod and the front...

I have a 2024 Yukon Denali w/ Mangaride. I want to upgrade the tire to the stock 22s on the truck. I am leaning towards the Toyo Open Country A/T III 305/45r22 tire. Still debating on the 2.5 inch leveling kit Rough Country sells, but I don’t want to mess up the ride. I hear that can be the case when you alter the suspension. However, it’s not like I getting crazy with the lift height. I see people doing it all the time with the leveling kits and either going with an aftermarket 22 or 24 inch rim. Any suggestions or advice would be greatly appreciated.

You can run that tire in stock form with no rubbing. My ex is on her second set on her ‘21 high country. Great overall tire.

Thank you for responding. I’m sold on that tire. Any advice on putting a 2.5 inch leveling kit on the truck? Will it change the ride up with also adding those 305/45r22 Toyo’s?

To be honest, those tires fit just fine in the wheel wells in stock form. I did add a 1” leveling kit to the front (after tires were installed) just to get the rig more level. That being said, they dont come with much of a rake anymore with the current gen (nothing like the prior ones), so imo if your gonna add 2+ inches in the front you absolutely have to add more to the back. Unless you like that saggin ass look. Unless you are looking for more height, just put the tires on there and see how you like it.

Ty for the advice! It is much appreciated. I am glad to get some honest and logical advice on this topic. I definitely don’t want that sagging look in the back! I will see how the tires look and go from there. There’s a guy I spoke with today that suggested 1.5” to level it out with the back. He wanted 600 for parts and labor and then I still have to take it to get an alignment done. I will go Tires first to see what it looks like. I will post some pix after it’s done.

I snagged a cheap “1.5” spacer lift off the internet and installed it myself. I actually think i did a small post/writeup on here about it. If memory serves me right it only lifted the front about an inch, maybe an inch and a quarter…which was fine by me, as there really isnt much rake in the new models.

I am going to check out YouTube and see if I figure it out myself before I pay someone. Thanks again for the help!

Heres what i used….

MZS 1.5” level kit on ‘22 tahoe high country

Just installed a 1.5” leveling spacer (lower strut style) from MZS. This is on a high country with no air suspension. Honestly not sure if these have mrc suspension or not, but i have been told they do. I could not find any sensor arms like on the last denali she had which needed a small spacer...
