This is the response I got from Customer Service:
"The only difference between the 2009 and 2010 frame is the wheelbase is longer. This is a good change as it will give you more tire clearance and be more stable in the rear end. Sorry for the inconvenience, it's rare for a bike to have all those issues."
Extending the wheelbase should help clearance between the front of the rear tire and the frame, but it doesn't sound like any more clearance to the sides.
I do plan to move to a 2.1 from the 2.35 which should help some, I guess.
