I did ghetto tubeless on a Maxxis Locust CX tire and Open Pro rims successfully. Held out amazing, and I was running them at 28 PSI (vs. 30 PSI with tubes) ... 700
x 35c. Worked well, fairly confident my tires were wire bead. In general, I run low tire pressures on all my bikes, the 28 PSI was simply to keep them from rolling (not burping) on fast turns.
