They never "sealed" well and would lost air far more quickly than my Conti GP5's will. I re-set them a few times, but they never sealed they way I would want. Do you think the tires themselves may lead to early drying to the sealant?
Nope. We've sold Pirellis since they came out with their bike line and noticed not a single difference between them and other tires we sell. "Had a problem sealing" can mean a lot of things. Using a TLR tire on a tubeless rim should have few if any problems sealing quickly. I have found that almost all probelems like that are caused by rim tape starting to fail or a leak around a valve.
