Not on an AEV you won’t. I have 37x12.50r18 Nitto Ridge Grapplers and have room to go bigger. I have never rubbed turning or flexing going into inclines.
Biggest tire on stock AEV?

Went to an off road show a few weeks back and saw an AT4X 2500 AEV edition with OEM Salsa wheels and 37x12.50 tires. Edges of inner wheel wells on both sides were chewed up. With hard turning at full articulation they rub. Spoke with the owner and he confirmed. There is a reason AEV makes a wheel well clearance kit for the large tires.

From a month ago post.....Here you go. This also allows for full articulation without rubbing:

I did not think to check. It did not look like it.
I had a similar issue on trucks of the past where big tire wheel combo fit perfectly without rubbing around town. Then when going off road where you are lifting a wheel off the ground it rubbed like crazy.
I'm assuming that the whole reason of going bigger is for more clearance for going into the back country on class 5-6 trails.

Have had them on for two days now. ZERO RUBBING. Truck should have come with 37s from the factory. I have turned hard into driveways and done full lock turns both forward and reverse in a parking lot. No rubbing at all.

For street they will work fine I'm sure. My comments are based on off highway use where you will be lifting a wheel and/or articulation at full lock. They will absolutely rub and tear up wheel well.
I'm assuming that's why you (or anyone) would mount the 37's. The extra 1" clearance can make a difference in break over and rock clearance.
Most anyone, at least in my group of off road buddies, gets lifts and larger tires for either launching boats or getting out to remote spots. I don't know of anyone who would go to the expense of big tires just for aesthetics.

For me part of it is the aesthetics as I think the 37s look really good on the truck. I daily drive the truck and don't use it for rock crawling or getting into really technical situations where there is a high chance of damaging something. I know the truck is decently capable off road but it is a very big HD truck that weighs close to 9,000 lbs. I agree with your point that it may rub during extreme articulation in technical situations. As far as my off roading goes I typically drive forest service roads pulling a camper in western Wyoming or use it to get to hunting spots on BLM land. Another reason I decided to change the tires is that in Northwestern Wyoming the winters are really bad and I did not like the OEM Goodyears in the snow. I wanted to go with a 3PMSF rated tire for better winter performance. There will be snow and ice here within the next couple weeks so I will update on winter performance but I expect the Toyo Open Country AT3 to be better than the OEM tires.
I stuck to the OEM size with my Mickey Thompsons and they are perfect at just a shade over 35". I love the torque on my truck and would do nothing to decrease it with larger tires. In any case its going to be a few years before I look to replace them.
