Hmmm - good question. I never considered that there could be an alignment issue. Everything else seems to indicate that it's well aligned - its an AHH with extremely quiet drivetrain, visually straight from the back, and the ride is smooth, stable and heavenly. The tires align perfectly with the rear fender. My experience has been that if I put on a set of JBs or Paselas (32C), and I let the tires get to about 1000 or 1100 without rotating, the rear tire will be toast (i.e. get a flat every other day from puncture). Once it gets to this point I have found it is too late to rotate them - the same tire will continue to flat once it gets to the front. I have had the same experience with 2 sets of JB greens and 1 set of JB blues. If I switch after 600 miles, I could probably get 1200 miles out of them. I found the Paselas to be almost exactly the same (however much cheaper). I also have had the beads separate from both types of tire around that mileage point.
My riding conditions, however, may be very different from others. I commute to work year round in Tucson, AZ on fairly rough roads (lots of chip seal, but not many huge potholes). From May through August, all of my afternoon rides are at around 100 deg. I think I read on the Schwalbe website that high temperatures will accelerate tire wear. I also strap my work bag with clothes and stuff onto the rear rack. With bike lock and lunch, etc. it probably averages 25 lbs. I myself weigh about 200 lbs. For reference, before the AHH I commuted on a racing bike with a messenger bag. I consistently got 2000 out of the 25C tires I used. It's probably a combination of everything and I certainly enjoyed riding on both JBs and Paselas. It's just that I now may have found my "nirvana tire". The Schwalbes are bigger (running 622-42 HS 366 with fenders), very comfy and seem very durable. Of course, it's not a fair test yet since the Schwalbes only have 1000 miles on them.
