It doesn’t feel particularly loose but it also doesn’t require a lever or any cussing which I can’t say for some of my tire and wheel combos. I’ve heard that you can build up the Stans strip for a tighter fit (which is why I went with 2 layers)- I could try a third I suppose, but I was worried about the strip actually impeding the bead.
Come to think about it, my tape job (first attempt) could be part of the problem- the tape drifts up toward the lip and fills in some of the space, reducing the contact of the tire bead with the lip. If that thin area happens to catch some hard lateral force it pops off causing a burp or a dismounting. Does that make sense?
