I know someone had this happen to them a while back after a negligent tire store installed them incorrectly. The S02's back tires fit on the front rim but they bulge a little bit. I just checked my rims and found one that's a front installed on the rear.

I'd like to read that thread again but cannot find it using the search. Anyone?

 

Are you talking about this thread:

Sheared lug bolts -- IMPORTANT INFORMATION

 

That's it! Thanks!
