A 60 series versus a 55 series has more sidewall height. Measured from the lip of the tire to the the tread the 60 will be taller. More sidewall equals more flex in the tire (generally). Which in layman's terms just means that a 60 series tire will not feel as precise or connected to the road as a 55 series. The stock tire size for the SVT was 205/55/15 (E0) or 215/50/16 (E1).

The 60's will look visibly bigger..hence looking like balloons...but since you're already running them on 16", you won't notice any differance.
