If anyone with experience/knowledge can help that would be great. I’m getting a 22’ 35 package.

Also would I need RPG 1.5”?

What brand of tire? BFG's will fit pretty easy I think. If you are going with a true 37 like Nitto then you may need the Perch collar with negative offset. The difference in a 37 BFG KO2 and a Nitto Mud Grappler M/T could be an inch or two. You will just have to try and see, you can always trim a little if needed.

It’ll be the Toyo Open Country AT3.

I think you will need the 1.5 perch collar. But I have 37 so I am just guessing. Someone has gotta have these tires on 35.

I completed the 37 wheel/tire swap on my 35 Raptor about 2k miles ago, I've noticed at highway speeds with cruise control and lane centering on the truck will pretty often do a lot more left and right wiggling with the steering wheel, to clarify this is not alignment and does not happen if I turn lane centering off, it's the computer not smoothly keeping me centered.

Is there any other settings I need to make in forscan or calibrations? I did already change the tire size in forscan.
Also I guess I need to point my headlights down some, they seem a little high sometimes.

I have this tire size on my 35 truck.

Fuel Block 18x9 +1 offset
Falken Wildpeak AT3W 37x12.50

There was definitely rubbing before RPG 1.5. After RPG there was still some very minor trimming to do. Mostly the inside bottom portion of the flare.

It rubs a pinch weld slightly if turning and going over a curb just right. No rubbing on the pinch weld during normal driving.

I will probably trim the pinch weld or maybe knock it back flat and out of the way, not sure yet.

I’ll take a few pictures of what I trimmed tomorrow.

That you for the reply. I appreciate it. What’s crazy is that I don’t even have my truck yet. I’ve been waiting for so long that my dealer is giving me a 37 that’s in transit instead. No mark up.
