I am almost NEVER riding with a perfectly flat (side-side) rear wheel. That's just not economically feasible for a heavy (200+) rider like me. +++++++++ During the Day, my friend Scott Steketee, a recovering varsity oarsman, had problems getting decent life from rear wheels. His solution still might work for folks who can do deep squats with a lorry on their backs: He rode and raced on 48 hole wheels. They were common on high end tandems back then; I just gave away a pair of new rims. We ran 48 hole SuperChampion 58 rims (?) and Phil hubs on our triplet and tandems w/o any problems at all, for many years. As usual, your mileage may vary, but might want to try the usual tandem lists.
