205/50-15. I believe that would be a slightly smaller diameter tire than my stockers which were 205/50-16. That would make mine sit a little higher than yours based on tire/rims alone. I will only be running the eibach prokit springs so nothing too low. Regardless this is the best looking bumper for the Focus period(after the true RS of course) imo.
