AT4X wheels/tires setup question

[Johnv76]

Question: Will a true 35/11.5/18 fit on the AT4X with the AEV front bumper?

It will fit. At the worst, you possibly may have just a small amount of trimming. However mine fit without any trimming. At full lock I have zero rubbing.

I had to add .5 spacers as I am running gmc rims with 295/70r18 as it was way to close for me. Before and after. Also notched the brake dust cover instead of taking everything off to get to them

Just purchased ‘25 at4x and looking into upgrading tires in near future, how’s everyone’s mpg so far with upgrade?

Did you install these before or after the peak spacer and blocks? Any rubbing?

The 285/75 18's were installed after the Peak Suspension upgrades. With my current setup, I have zero rubbing at full lock, and with the suspension fully extended and tucked up into the fender wells.

Wheel spacers as well? Good intel and appreciate it. Our of curioisty, how come you didnt do the full 2" kit with the lower collars? Are you still on stock UCAs?

The 3/8's wheel spacers were added last, "after the 285/75 18's". I did the wheel spacers more for aesthetics than function, as there was enough clearance from the tire to the UCA "barely lol". You can view my build channel on here by clicking the link in my signature to see pics and details.

I have a 2025 AT4X with the AEV front bumper and I will definitely be putting 295's on when the time comes. GMC dropped the ball and really should have put 295's on these trucks, 275's are way too small! Here is a pic of my truck with stock 275's. I have a Rough Country 1.5" front level kit installed.
