like i said before i dont know much about tires.....but why would the engine/trans matter when buying a tire size?? does it have to go with how fast ill be going or whats the deal?
tire size has a affect on the auto trannies shift points as well as the final gearing,your tranny is calibrated for a certain diameter wheel,by going to big or to small you can mess things up...i wasnt saying you shouldnt go with 225's for that reason...we had that discusion a couple of weeks ago in another thread  ...i was saying that b/c 225 is going to suck up a little of your cars (precious) power..etc,225 would be good for running a modified duratec..turbo'd zetec etc to help with traction on hard launches,or for handling purp. on a roadcourse or autox..but for a everyday driver zetec atx 215 is plenty of tire...my 2 cents
