OK here is the deal I want to get the pro comp 7005 series matte black in either 18x9 or 20x9.5 the tire I wanna run is either a Mickey ATZ 375/60r18 (36x15.5) or the baja claw rad. will those wide tires work on a 9" rim or do I need a 10"?

 

I'd go with a 10 inch wide wheel minimum.

 

I AGREE. not only would you be cutting it close with a 9" wheel but that tire will look super funny because of how much it will be pulled in.
