I am going to blame the valve stems since they are the cheasy rubber ones you get at the tire store, but otherwise the wheels have no punctures ... and the FE gains I got are indisputable.

But yeah, I may rename my Vibe the Radio Flyer, because it does ride rougher, but coming from low riders, it is very tolerable.
I heard that you can request "high PSI" valve stems that are designed for truck tires (I think). I would have done that had I known about them.
