Small leak in tire question?

[dgm3]

Anyone know of a good trick to figure out where a leak is coming from on one of my Fikse/Hoosier combos. I am fearful that it is the seal within the wheel. I've tried to find it by pouring water all over it, but I think this leak is so slow that it is not obvious.

Thanks.

Bring it to a local tire shop, gas station, or Costco (where is free if you're a member) and have them check it out. If they can't find it by lifting the car, they'll take the wheel off (which cost more) and dunk it in a bucket of water.
