I noticed most of you guys running the 18x10.5" rear wheel are running a 305/35/18 tire. Will a 285 fit without compromising handling? I ask because I'm not ready to make the leap to R Compounds yet, I will probably do one season of HPDE on street tires. However, the tires I want to try the NT555 or Dunlop Star Spec don't come in these mega widths. Having said that are there any other decently priced semi sticky street tire recommendations?
