JBA UCA clearance with 285s

Does anyone know if 285/70/17s mounted on TRD Pro SEMA wheels (17x7; +4* offset) will rub against a JBA HD UCA? I know it will be real close, but I'm curious if anyone has actually done this successfully.

 

The site says 4” backspace should be fine. The Sema wheel is a +4 not a lot but it will be close .

 

I have stock trd sports 285 75 17 and they werre super close had to use spidertrax 1 1/4. Also was hitting frame, lost turning radius

 

What's the offset on those wheels? I don't mind close as long as I don't actually rub.

 

According to my limited research on Sport wheels....17"x7.5" with 6" backspace & 30mm offset. Keep in mind he's running a 34" tire or 33.8" tall by 11.2" wide. 1" taller but the same width as yours.

I'm currently doing some mental gymnastics in relation to my new setup.
285\75\17 Duratrac
FJ Cruiser wheels 17x7.5 with 15mm offset & 4.84" bs
I currently rub on my frame and UCA.
I had 1" spacers but pulled them due to excessive rubbing on front & rear of fender.
Now considering .75" spacers.
Any input thoughts would be appreciated.
