These are the perfect tire sizes for the OEM Competition package wheels which are 0.5" wider than the standard 19" wheels. 255/30/19 is absolutely not the right size for the front of the car. It's a full inch too small (that is a recommended 20" tire size). The 255/35/19 Might rub at full lock on the rear portion of the fender liner due to the slightly larger overall diameter (this is hit or miss depending on the tire brand, wheel offset, and tolerances of each individual car). This is not a big deal; its very minor and only happens in slow speed, full lock situations.
The ZCP rims have a different offset,on stock 220's 255/35R19 rubs...if you want to mislead people here,by all means do.
Like the OP, i experienced the same rubbing on 220's first hand, not based on some google search.

220M: Fronts: 19x8.5 (offset +29) Rears: 19x9.5 (offset +23)

ZCP: Fronts: 19x9 (offset +31) Rears: 19x10 (offset +25)

255/30R19 overall diameter is 25.2".
245/40R18 overall diameter is 25.7".
245/35R19 overall diameter 25.8".
