I have 225/50 - 16 Yoko ES100s on my C230. This size wheel and tire series 'tramlines' more than the stock 15" wheels and tires, more so with aggressive and sticky treads than with conservative touring tires. On mine, while it is more apparent than with my 16" all seasons were, it is just barely noticeable on some sections of road. Going from 195/65 15s will accentuate the difference in road feedback even more. Also, did they do a real good alignment and spin balance the wheels on the car? What kind of tires did you install (Performance, Touring, or ???)
