I think with my snow tires I had basically enough clearance to allow for snow buildup when snow wheeling. I have a set of 275/70R18s on oem alloys and they just clear the body mount by like 5-10 mm, just.. and that could just be my alignment and it can rub on most other trucks. If they cant get you there with an alignment, (which i doubt, thats over an inch compared to when I was.)

Scrub radius is a real PITA. I am mechanical engineer and still **** it, myself, on my first few builds.

So did I screw up by getting the -15 offset? I thought I needed it for the tires to clear the UCA assembly…I know a lot of folks with same GX and tires without this issue

Get an alignment and have then push everything forward if your lower UCA isn't seized.

I have been rubbing in my UCAs for 3 years and about 50-55k miles. I was commuting with it across the Pawnee grassland.

I have never gone wider than a 285, though.

Will do, but this is not UCA rubbing, it’s lower body where the shock assembly fits in

was it here?

Yeah, you can see where I’ve got the fascia pulled back by those yellow zip ties but at full turn the tire is rubbing on that metal body section ever so slightly. Pic is taken from the ground looking up. I haven’t driven around since I did the zip ties so I’m not actually sure how much I cut down on the horrible sheering noises of the fascia rub and if that metal rub will even be super noticeable but I’d prefer to avoid rubbing of course

Thats the body mount. Its hard to photograph. I just got my body mount chop today.

Any of the liner or step that rubs isn't a big deal but the body mount will damage tires. It did a number on my yokos. Missing a few lugs and will probably lose a few more. Lesson learned, will get the 4Runner a BMC before going bigger than 33 on oems.

Ok, so when folks are saying BMC they’re referring to this too? I thought it was just front fender rubbing they were talking about. Wondering if that alignment plus the extra lift from 1.75” to 2.5” will help and can avoid that chop

Alignment might help, lift won't. I ran that size on no lift for almost 2 years. You wont have issues hitting the top of the wheel well until you go to 35s. Everything you will hit is in the front and back of the wheel well.

Same size with no lift? Dang. Did it not rub or did you not mind it? Mine looks like it’ll only be an issue at full wheel turn anyway. Just annoyed it’s even happening.

It only rubbed on plastics. I didnt get BMC rub until I had 285-75r17s.

Alright. Wonder if it’s my negative offset then

Thats not helping. I think for every 3mm of offset you increase the scrub radius by 2mm. So lose 2mm of body mount clearance.

Here are some pictures I grabbed of what my BMC looks like. And the chunks missing from my tires. I am customizing my tread, apparently.

You need a BMC to run the negative offset wheels. When I ran 285/70/17s on 17x8.5 +10 wheels it would just clear the body mount by a few mm. I switched to 17x8.5 -12 wheels because the +10 would rub on my relocated swaybar brackets and had to get a BMC.
