Putting a 285 on an 8.5" wide rim is retarded. You need 10" wide wheels for a 285 or you're spending 285 width dollars for 235 width performance.

 I suppose it depends what kind of tires you are talking about.  2 top-level BS drivers at SD were on 285/30-18 hoosiers on 18x8 SSR's, one of them placed 2nd in class.  Another back east is running 285/30-18 kumho's on 18x8 SSR's, he took 1st at the Dixie NT.  We tried the 285 hoosiers last year, they look weird when mounted but they launched great.  I did not think they handled transitions well, but I may just needed to have learned to handle them differently, or the car setup may needed to have been adjusted for them.
