G'day Reg,
I have 14 x 6 Superlites on my car, they were on it when I brought it running 185/60 and wish they were either 13's or 15's. The main reason is the and lack of dish on the rim and the choice of tyre and the fact that they don't fill the guards at the rear which is the look I am after. In 14's, there is little choice of tyre, usually just 185/60's and 195/60's, if I could get a 215/50 it would give do the trick. I have seen many escorts running either 13 x 7 or 15 x 7 and look awesome. In 13 inch you can get 205's, 15's go a 195, but the dish of the rim looks much better and gives the car a nice stance. If I was in a position to replace, I would jump at 15 x 7 and run 195/50. I am not sure if you have seen the following websites, but have a look and track down some photo's of others cars to help you decide.
