Quick question about BFG Radial T/A's

I have 205/70-14 on my Dart w/ 5.5" wheels. I think a 205 is probably the widest tire I would put on my wheels. Of course, the series of the tire may make a difference. Not sure if going with a 60 series would lessen the bulging effect or not. Perhaps an expert on here can either debunk or verify that.

Not too much bulging going on yet, as you can see, but anything bigger would probably be too much tire. My advice, as others have pointed out, is to take the wheel off and make sure it's a 5.5". Only takes a few minutes to check. Good luck.
