Tire fitment question

Hey everyone, I've got a set of Impala SS rims that are 17x8.5. Now, these originally came with 255/50/ZR17 tires on them. Tonight, I put a set of 225/55/17s on them because I got them at a good price. Is this a safe combination to be running? The Z rated part doesn't bother me because this car goes 75mph maximum, but they do look rather ballooned on the wheel. Can anyone tell me if there is a rule of thumb on whether or not this would be an approved combination? Thanks in advance for any help.
