Rally wheels on early Dart???

i also have a set that i have yet to put on my 65, and from the pictures, it looks awesome. a question though. the ralleys i have currently have tires on them. al in great shape, the problem is that i think 2 of the tires are probably too big. the fronts have 205s and the back has 235s. can anyone tell me if they are too big before i try? my thought is to put the 205s in the back and put 185s in the front. any ideas?
