Tire spacing on a 99 UZJ100? will 315/75R16 rub?

I've searched the tire threads (well some of them), and can't find out if a 315/75R16 tire will rub at lock with the factory alloy wheels. I have a 1" body lift, but I'm concerned about back spacing. I'll be adding the 1.5" OME lift as well. Is there a different wheel set-up I should be looking at? Apologize for the newbie question, but I'd like the extra clearance of the 315s, if I can make them fit. Thanks, Spank.
 
It will lock at full turn on the sway bar and the frame. Wheel spacers, or not turning to full lock will alleviate this.
 
Duggy-

Thanks. Would steelies or a different offset wheel do the same thing as a spacer?

Steelies (or any other rims) in the correct offset would behave the same as spacers.

I have Slee spacers now and can turn at full lock without issues on 315 KM2s

I have 295's with Slee spacers and I, too, do not rub on the body/frame, UCA or sway bar; however, when fully stuffed these tires just barely hit my fenders. I didn't notice this until recently. Both my fenders have indication of tire rubbing and one of them is slightly (just barely) bent with the paint cracking.
I have to imagine that 315's will eventually destroy your fenders if you intend to 4-wheel the vehicle. I think to avoid this you need not only your 1" body lift, but also a 2.5" suspension lift.

I haven't hit my fenders yet, but I think it's coming soon. We'll see.

@Hayes

Could you explain?
 
Regardless of the coil or torsion bar, the suspension moves through the same range and along the same paths. Cranking the bars and/or adding stiffer springs just changes the static position of the suspension and makes it more difficult to full compress the system. But if the tire rubs a fender when fully compressed, it will still rub when fully compressed on stiffer springs. You have to change the position of the fender relative to the suspension links by:

1. Moving the fender (body lift)
2. Move the wheel (backspacing)
3. Moving the links (change the geometry)
4. Limiting the travel (extended bump stops)
 
...Cranking the bars and/or adding stiffer springs ...makes it more difficult to full compress the system.

That was my point, although not quite as articulate. With more lift you still can hit the fenders, albeit less likely;)
 
Thanks for all the input, guys. One further question. I'm looking at using 18" Tundra steel spares as the wheel for the basis on the BFGs now. I can't seem to find info listing the backspacing on them though. Does anyone know? They look like they have less backspacing (good for me) than the current TLC alloys (about 7"). I just don't want to order a set and find out they have too much backspacing. Thanks, Spank
 
re_guderian-

I've had zero luck in my area. I'd love to find a set and be able to confirm backspacing. I understand the weight issue.
 
have any of you tried running 20" rims? What size tire? I would like to get ride of some sidewall flex and was thinking of a 35" tire and 4.88 gears.

I'm guessing you meant "Get RID of some sidewall flex"? I'm assuming you don't take your 100 offroad at all? (Nothing wrong with that, just assuming by your desire for 20" wheels)

There are certainly 100s with 20 inch wheels, but they wouldn't be beneficial to anything off pavement. Even on pavement, you'll be using a shorter (and stiffer) sidewall, which means your pavement ride will suffer as well.
 
^To answer your question a little better....

A 305/50/20 is a wide 32-33. You'd probably need spacers.

A 295/55/20 is a 33 You may need spacers

A 285/60/20 is a 34 You may need both
 
We take our land cruiser off road very rarely. It is used more like a suburban really hauling trailers six kids and all their gear motorcycles etc. it has heavy bumpers on both ends with large cargo trays on the rear swing outs. It is mamas daily driver and I'd like to get rid of some of the body roll. Think spacers to make the wheelbase a little wider and shorter profile tires would help a lot. I am running the OME 864 heavy springs in the rear with the 2.5 inch lift in the front with differential drop.
