Dom I too have changed to a hoosier 29/10.5w/15 most of the time on my Dart.

This tire is the same size as a QTP 29/13.5/15. For me no real et change, but 60' is a little more consistant and reaction time is a little quicker and sidewalls have lasted longer. Still like my QTPs when I want the "Its just a street car" look.
