There are several manufacturers that make a quality 285/30/19. The Continental ContiSportContact 5Ps are an excellent tire. These are OEM in the GTS sizes on the Merc. AMG cars. I had these and these are definitely up there with the Mich. PSS. Also, I currently am running the new Toyo T1Sports in the GTS sizes and I am very pleased with them. Also, Pirelli Pzeros come in the GTS sizes and these as well are OEM for the Merc. AMG cars.
