It's very common to see this in tires that size with stock tires. Did you try to crank the steering over and see if they still clear? It'll come even closer if not hit.

no i have not, i have been off road with them aired down to 16 and do not see any rubbing marks on them, and this was with some extreme angles,(Hey i was following ncfj) he took me down some trail i never imagined i would try. so should i be concerned, is my question.. thx

Try cranking them over on pavement and see. You can even do it in your garage. If they clear I wouldn't be too concerned, but if they rub or come very close even just on pavement, I'd consider either spacers or aftermarket UCA.

When you air down your tires they bulge more at the bottom where there is pressure, not so much at the top where the UCA is.

Mine were about as close as DominicG's are and they never rubbed on the trails.

I've had 285/70 17 BFG A/T's on my rig for a long while now, still have never gotten any rub on the UCA or body mount.


i do not seem to have any body mount issue, just went out and stuck my finger in between the uca and the tire and it sure seems close imo. if you were to shock the tire good enough it seems like it would be real close. so I am now considering some wheel spacers to get it further away, and by reading a few other posts this made me wonder if i space the wheel away from the uca that it might cause my tire to come closer to the body mount. input?

Mine have never touched and have been worked off road pretty hard.

Also, as Layonn pointed out, regardless of the pressure, the sidewall bulge is on the lower half of the tire.

Finally, when the suspension compresses, the gap increases, although I guess there is potentially an issue when the suspension is at full droop, but I have never had an issue either way.

I couldn't get 285's to fit my current rims. They were less than a 1/2" from the UCA and when the wheel was turned they rubbed. Discount did a trial fit for me. That's why I am still running 265's. I think it is all about the offset of the rim.

I just got 285s for Mother's Day. I have not noticed any rubbing at all but I only put about 100 miles on them today.

thanks for all the replies.. i wasn't sure if in the future i would have a problem with them.

Congrats on your 285's Kim..

So if you do install spacers on the hubs, does this move the tire closer to the body mount? is seems like it could because without the spacer it is behind the mount more, and moving it out would put the tire in the middle of the mount? correct

I noticed the same thing and got to wondering about spacers as well. Then I went and jacked the wheel up all the way and then jacked the FJ up with one of the front tires at full droop. No rub at all either case, and it stays pretty considtent at about 1/2"-3/4" space. I had slight body mount rub at hard crank coming into driveways and such without a lift kit. Since the OME 3" I clear the mounts but think that wheel spacers will push it closer to the body mount. Everyone of the wheel spacer posts I have seen have been people running 1" or 1.25" spacers. You can get 1/4" or 1/2" spacers and maybe not rub on either area.

Mine rubs on the inside of the fenderwell sometimes.

But of course, I have been known to wheel pretty hard sometimes...

Still would not trade them.

From what I am reading, I would also think that just a 1/2 inch or so spacer should make you feel better, and still not rub.
I thought that 99% of the 285/70/17 were fine, but I guess I do have 16" so I could be wrong.

Maybe I'm missing something...

As an example from the BFG Website

Stock size tire:
LT265/70R17/C 112R RWL 12665 7 - 8.5 10.7 on 8 31.8 16 654 [email protected]

Thread discussed tire size:
LT285/70R17/D 121R BSW 14517 7.5 - 9 11 on 8 32.7 16 636 [email protected]

This tire is only .900 larger in Dia / .450 in Rad
This tire is only .300 wider in section width / .150 from center of wheel

This isn't really enough to make any huge difference is it?
Size difference is neglible unless clearances are so tight from the factory and the Toyota designed geometry simply requires suspension modifications to accomodate this increase.

Mine has never rubbed, even on the trails it barely touches the body mount, as for the UCAs it never rubbs even when the tires are aired down. :cool:
