My car is lowered an inch on Eibach springs and KYB GR-2 struts, along with a beefy aftermarket rear swaybar. This combination is used by other Elantras in autocross, and they report problems with tire grip all the time. Personally, I want a sticky tire to help alleviate the problems of grip.
195/60-15 is a full inch bigger than stock. 195/55-15 is 1/3" greater than stock. I think the previous owner calibrated the speedo to that circumference tire, as the car was wearing 185/65-14 tires when purchased.
