And this was with one of the Tektro long reach calipers you mentioned.
Did you also use Tektro's brake levers with the calipers? Like these:

These have a qr button in the lever just like Campy Ergos and, that release coupled with a qr on the caliper itself, really opens the calipers WIDE. I have a similar combination (Tektro levers and Shimano 105 brakes) on one bike and it seems with both qr's open they would clear a car tire.
