I'm sure I missed it, but have been following your thread. What size tires are you currently running out back? I've got 215 70 14's currently but going to go a little wider on the rear for the staggered look.
The rears are 235/60R15, but they are too wide for the rim (I believe they are 15x6). I think I'm gonna go with a 225/65R15 or 215/65R15. The 15s I currently have on there have a overall diameter of 26.1" and 65R15s would be 26.0", so not that different. The 205/70R14 are 25.4" tall, so pretty close. Also, I personally would not really go wider than 205 for the front, because I don't have power steering and it's a pretty good workout to parallel park as it is. Remember, this is a big city fish...
