need tire sizes for 18 x 9's please
 

I just got some sweet Y2k Cobra R knock-offs-they are 9" wide (not 9.5" like the OEM R wheels). Does anyone who makes the right tires for optimum stance/traction? I would like to stay away from really thin sidewalls if possible and need drag radials for the rear. Thanks!

If you wanted to stay away from low profile tires you should have stayed away from 18" wheels. 265's or 275's fit really well on a 9" wide wheel, but you are probably looking at 35 series for appropriate tire height.
