OK, So I had 255/35/19 and 275/35/19 Toyo T1R's and had no issues with rubbing. Then I had Kuhmo SPT's put on, same sizes. On the way home from the tire place I took a local canyon and heard a clunking type noise coming from the driver rear tire.
So doing research I found end links were probably the cause so I switched them out for powergrid. Didn't fix the problem, and now I am starting to see slight rubbing on the tire. Could this be a blown shock causing the rubbing? The passenger side is fine and the sound/rubbing did not occur when I had the Toyos on. My suspension is Hotchkis springs/sways and Tockiko D Specs.

 

rubbing as in hit your fender?

shocks do not control the ride height, springs do. So I would not blame them on the rubbing just yet. You say the tires are the same size, but are they the actually same diameter? Just because the sizes are the same does not mean that they are exactly the same. Some brand of tires run wider then others, some run higher than others.

Do you have any pictures of said rubbing? perhaps all you need is a tad bit more negative camber.

 

Yea I was thinking it might have been tire size, but Its odd to only happen on one side.

 

check the alignment?

 

Here's the alignment I had done recently with the install of the End links.

 

move the rear camber to -2 and I bet the rubbing will stop. or just roll the rear fenders. I would try the camber first myself though.

 

Ok, I'll try that. My camber was at -1.9 before that alignment was done, and I still had rubbing sounds, but no marks on the tire yet. But I want to avoid fender rolling so I'll try the camber first.

 

the most I would go is -2.5, which is what I ran all the time in the rear of my Z
