Just acquired a 1978 FJ40 with 17-inch rims and 285/70 R17 tires. Rubbing on tie rods when turning hard. What is maximum width size recommended to avoid rubbing?
 
Might be a back spacing issue? I would not turn that sharp, when you hear it rub - back off until you don't hear it rub. I have been in places where its a 50 point turn to get out - a little rub at that time might be only a 10 point turn.

Post a photo of where the rubbing is.

A back space issue, plain and simple. If it rubs either static or with a turning deflection try a 1/4" wheel spacer on the front to clear the tie rod ends.
Agreed, ... backspacing issue. You might be able to go to a 255 or a 235 tire width. If you go with a spacer, you might need longer studs.

A backspace of 3.125 inches was what we went with to run 16" wheels and disk brakes, ... and we run 255s.
 
My .02 cents, I would buy a set factory wheels and 33x10.50s and sell those wheels/tires on FB. ASAP. It will ride better, steer better, look better and won't rub.
 
Quick and easy, you could try 1/4" spacers. You still may need longer studs because of the rims mounting flange thickness. A thicker spacer will probably require longer studs or something like the spacers you linked to. The problem with the spacers you linked is they will really be noticeable because the tires are going to stick out.

These might not be thick enuff, but would probably help.
