Certainly the issue has been discussed, but . . . don't remember the thrust:
What is the downside (if any) to running tubeless tires with tubes installed on non-airtight (as in, spoked/unsealed) rims?
Tried to sell some new tubeless Continental TrailAttacks to a KLR owner; he ran, screaming, from the room. Don't know his objection; I, naively/unwittingly, have run tubeless tires with tubes installed on spoked wheels for thousands of miles, with unknown consequences/risks. Am I living dangerously, but just lucky so far?
