Assistance With Wheel Rubbing

Hey guys, hoping someone can lend me some insight as to what I am looking at.

A while ago I got a set of TRD SEMA wheels and followed-up with some Falken Wildpeaks. Was all good at the time. More recently, I did a full suspension upgrade and noticed that my front tires were coming real close to the cab-side, sometimes rubbing when turning or at full lock (backing up and such). Originally, I wanted to keep my mudflaps on, but I ended up taking them off as they were rubbing too much.

I haven't seen other people have this issue (though I am certain I am not the only one) so I was seeking some assistance in if there is anything I can do to remedy the situation. Pictures are attached as where the truck currently stands today.

Specs
Wheels
TRD SEMA Wheel
17x7.0
4mm offset
??? backspace

Tires
LT265/70R17 Falken Wildpeak A/T3W

Suspension
Fox 2.5 Coil-overs with Reservoir (not sure of the current ride height at the moment)

Alignment
Before:
Caster: 4.75 (L) 4.75 (R)
Camber: 0.75 (L) 0 (R)
Toe: 1/2" in

After:
4.50 (L) 4.75 (R)
Camber: 0 (L) 0(R)
Toe: 1/16" in

Any help / insight is appreciated.

 

Painfully common. Cut the cab mount (search for cmc or cab mount chop) few vendors even offer laser cut plates to scribe and reweld in place to give you the clearance needed

 

Really? Damn it. I know I would have to do a cab chop if I went up to/larger than 285s or something, but I figured the 265s would be okay...

 

I've heard it's more of an issue with wheel backspacing, but taller and wider tires just compound the issue

 

If its possible, it may be worthwhile to try and get more caster into your alignment. Do you have aftermarket upper control arms? Also, maybe post some pictures of your alignment eccentrics and someone can give you an idea if more caster is possible. It may not help too much, but we all know that every little bit helps.

 

I was just going to say the same thing. I agree with looking at caster as said above

 

I do have aftermarket UCAs. Dug around and found my last alignment specs:

Before:
Caster: 4.75 (L) 4.75 (R)
Camber: 0.75 (L) 0 (R)
Toe: 1/2" in

After:
Caster: 4.50 (L) 4.75 (R)
Camber: 0 (L) 0(R)
Toe: 1/16" in

 

That's a nice looking alignment to be honest. Which arms do you have?

 

I have the same tires and they rub. I think they are a little bigger then other brands.

 

How much lift did you end up with? The lower the lift the more the aftermarket castor correcting uca's move the tire towards the rear. In the end you may have not needed the additional castor.

 

I currently have Camburg UCAs installed.

 

Can't say off the top of my head. Would need to go out and measure.

 

Theoretically your caster should be closer to 3*, but more positive caster should be helping you NOT rub the cab mount, as it is pushing the wheel further forward.

Kind of odd you're rubbing with that much caster and only 265's. I would think a lot of that is your wheel offset.

If so, what can I do about the offset (increasing, I assume?)

 

General bump to see if anyone has other thoughts on the matter...

Also pinging @Speed Freek to see if he might have any input

 

Hey bud, some tires have a larger OD due to the lug design, looks like yours are one of them and its just large as your specs look fine.
I have done well over 200 cab chops, and some even on "smaller tires" like yours.

I say do the CMC and then you are good to go, its going to rub super bad when you are in reverse and the wheel is stuffed. I do at least one a week.

 

^ this. Even my stock size 265/70r16's rubbed on my 04 because of the backspacing of the aftermarket wheels I have. Rubbed at full lock on the pinch weld/cab mount like your's are, I had to take an angle grinder to it. Being that your truck is newer you might want someone do a CMC though lol

 

Really with aftermarket uca’s you’re gaining castor from the top side of the suspension travel. It isn’t so much pushing the tire forward as it is leaning the spindle back. So more castor doesn’t necessarily guarantee more tire clearence just better tracking.

 

If you have camber bolts in the lower control arms, you can adjust the rear bolt to push the rear of the arm out and then adjust the front one to pull the front of the arm in. This will effctively place the tire further forward in the wheel well. Yes you'll need a new alignment. Since you have aftermarket uca's, the fine running might be able to be handled by the upper adjustments. This works great with SPC uca's as they have adjustable upper ball joints. I'm not familir with the uca's you have.
Good luck
