Raptor stock wheels vs. Method Fat Fives offset

[ZBoater]

So stock Raptor wheels are 17" x 8.5", 6 lug x 135mm, with 34mm offset( 3.41 front space, 6.08 back space).

When compared to Method Fat Fives 17" x 8.5", 6x135mm, with 0mm offset, 4.75" backspace, what is that going to do to the tire? Push it in, pull it out?

And, if on top of that I'm putting 37" x 12.5" tires, with this different wheel, how much will this stick out, if anything?

I've read the offset explanations but I can't apply the knowledge. Help the newb out please!

The methods will push the tires out more (1.33"). Looks better to most, but makes contact with the fender flare more likely off road. You will be fine on-road with "small" 37s and mid perch, but expect a little rubbing when the suspension is compressed at full lock.

Use caution. I have Method Fat Fives with Duratracs. Not 37s. I get rubbing in reverse hard turn.

Others do not get the rubbing.

Thanks guys. Appreciate the replies. I needed to understand the impact of the Method 0mn offset vs. stock. So it seems it will push the tires out a bit, which I like.

I was looking closely at my stock wheels and tires, and I just don't see the fronts "tucking" inside the fender flares under full compression. The way the tires sit now, the outer edge is directly below the bottom edge of the fender flare. If it compresses all the way up there, it's gonna hit. So having the new tires stick out won't make a difference. It will just hit that much more.

So my two "rub mitigation" options are to go with a "smaller" 37" tire (BFG or Nitto Terra Grappler) and do the mid perch. I was quoted mid perch by the folks doing my install, so now I have to decide on the tire.

I have a hard on for the GYs. I have a nagging suspicion I'm just gonna do it and deal with the consequences later. Screw it.

No prob, I keep that diagram around cause its easy to get mixed up with front/back space and pos/neg offset.

The stockers will tuck, camber goes negative at bump and the top of the tire "tucks" in. The flare has a lip that extends into the wheel well a little, you can cut this to gain some clearance as well and it isn't visible unless you're already in the fender well.

Like a previous poster mentioned, use caution when steering full lock and backing up, particularly if the parking lot has pot holes. On the truck in my avatar I had 37" Generals, Boatec fiberglass and custom fender liners at top-perch height. Made contact bad enough to damage the fender backing out of a pothole ridden parking space! (not my proudest moment picking up the pieces of my "badass offroad machine" in the hobbytown parking lot)

That said I will be running 37" BFGs with methods and mid perch on the new otherwise stock raptor. There is a small relief cut that can be made in the liner to lessen (eliminate?) rubbing, I think Raptizzle has posted pictures of it in one of his threads. I'll post up with my experience if I can ever get my hands on some damn tires!

Check out the photo from this other thread. It gives a better idea of what the wheels do at full compression. They don't go straight up and down. Pushing the wheel/tire out an inch or two makes a big difference in the travel and whether or not it hits the fender.

See how the wheel/tire go up at an angle? That's how it tucks in.

Ahh! Thanks for that. So the issue is a 37" tire being 2" taller it might not tuck in enough to clear the bottom of the fender flare, and thus the need for trimming.

Got it.

So mid-perch gives you what? Another 1"? So you are still going 1" beyond the stock setup? And if you get a "smaller" 37" tire, you reduce that even more.

Interesting. I still haven't purchased the tires, plan to do so next week. I'm still leaning towards the GY (36.8") but still need to chew on it.

Thanks!

I'm on Falken Wildpeak ATs which are about 36.6 or so on stock beadlock wheels. I'm on mid-perch. No rubbing for me. That includes off road. But I don't jump my rig and get full compression. Also, note the width of the tire you buy. A lot of guys are buying tires that are also wider than stock. That just adds to the rubbing issue.

Good point. I noticed yours are 12.5" from your sig. I don't think you can put much wider on the stock wheels, can you? I'm thinking of going your exact same size (37x12.5x17, actually 36.8") on 0 offset, 4.75" backspace.
