315's on FN wheels

So I looked around and I've gotten a lot of good information about big 34-35" tires fitting onto our rigs; However, I am gonna make this post to request some specific suggestions / knowledge - forgive me if that's super obnoxious.

I currently have 5100's all around, OME 885's in the front (with a 1/4" spacer up front) and superflex rears. All in all I believe I have a full 3" lift.
I am going to install a 1" body lift next week as I am looking to upgrade my tire size from 275's to (hopefully) 315x70x17. I'll also be switching from 18" limited wheels to the FN F(x) pro wheels (which I believe have the same offset as stock wheels + 1.25" spacers).

My worry is this - I know I will have to do a bit of fender trimming as well as a BMC.. That's fine with me - Off the top of your head, do any of you think I will run into a (stock) UCA problem / anything else? I don't do any serious off-roading (yet) and just want to be okay to cruise on the road without any rubbing (or at least, very minor rubbing at full lock / reverse).

The tires are BFG A/T's which I have read sometimes are a little more of a chore to fit than some other tires that are the same size (I may be wrong on that) - But I am hoping to get away with just a hefty BMC and some fender trimming to make them suitable for on road use. Once they are on over the next couple months I will work on getting them ready for some off-road flexing.

Any response / help is much appreciated - Thanks!!

With the different setups I've had I believe that if you don't have a minimum of 5" lift combined you will be doing a ton of trimming. The pinch welds will need to be hammered flat, most of the inner plastic liner will need to be removed, (I left a section to help cover the air intake), front fender will need to be trimmed in front and behind the tire, the rear bumper will have to be trimmed quite a bit behind the tire as well. I rubbed on my stock uca's with rims that stick out 1.25-1.5" further than stock. Nothing terrible, but that all depends on tire too as some are more squared off than others. At full lock I slightly rub my frame rail, but the only reason I know is that it rubs the paint off in that spot.
Tacoma guys are actually cutting the pinch weld right out, welding in a piece of flat sheet metal that is moved back so tires don't rub, then cutting off the body mount completely, making a new one 3" behind it and running 1/2" plate steel to the existing body mount hole so you don't have to run a new hole inside the truck. They then run 35-40" tires with minimal lift, like 3" or less.
I can take pics of my cutting if you'd like, and they are in my build thread somewhere too. I actually trimmed more of my front bumper than needed on purpose, but that was to help with approach angles.
35's = :party:

Got a picture of what you're talking about with the tacomas? I'm gonna run 35's next I think, but I have a while since I just got new tires but it never hurts to prep

I appreciate all the info! If you could get me a pic of your cutting that would be awesome. I'll replace the UCA's eventually, if it's not horrific rubbing on the UCA I may deal with it for a short period of time until I get some more finances sorted out.
I'm wondering if I should go a setting up on my 5100's when I put these things on to give me a little more wiggle room? Just hope the ride doesn't go to shit.
 
As I said, I trimmed my front bumper more than necessary for ground clearance, but you should get the general idea.

Thanks bud! I'll be sure to post pics when I get to this! I'll probably harass you via PMs since I'm a newb. Lol
 
Daaaaamn [MENTION=101553]t-man[/MENTION], got any more pictures of your front bumper? Looks interesting!

Actually I just found a few on your build thread. It really doesn't look that bad!

No I thought it came out great personally. I'm going to use my offroad lights as turn signals soon so I may trim it up more.
 
Hey [MENTION=101553]t-man[/MENTION], looks like you have removed your front sway bar. Correct? Im embarrassed to ask because I've read your build twice now, and I should know.

Front and rear are gone. Much better ride and flex without them. You need to have stiffer springs to run without them or you'll lean to much.

I was just making sure that I was correct when I didn't see it. No intention's of taking mine off. Thank you sir.
