I tried to set up the
"new" Pari-Moto (gumwall, no anti-puncture belt, 38mm, NOT tubeless-ready) tubeless on my PL23 (tubeless-ready) rims... without success.
The tire bead settled into the PL23 rim pretty easily (with an air compressor), and I used about 4 oz of Stan's sealant per tire.
The problem is the casing of the "new" "basic" Pari-Moto is pretty thin, and the sealant kept foaming through the sidewalls. I'd air the tires up to 40-45 psi, and they'd be down to 20 psi within 20 minutes. Even after 6 weeks of this cycle, the sidewalls continued to leak. My friend had similar sidewall foam with his Hetres tubeless, but they eventually sealed up.
After two falls due to low pressure, I replaced them with a new set of the same Pari-Motos with normal tubes, and haven't had a flat since (~1500 miles).
Perhaps the "gravel" version of this tire, with its anti-puncture belt, would have a substantial enough casing to set up tubeless. But the "basic" Pari-Moto tire is definitely not recommended for tubeless use.
They provide a fantastic ride, however. Fast, comfortable, fast, sure gripping, and fast. Did I mention fast? :)
And, they've been surprisingly durable. I have ~1500 miles on this set, including commuting on debris-filled streets and riding on limestone gravel. In that same amount of miles on the same roads, my Grand Bois Lierre tires had ~8 flats and were completely finished after ~1500 miles. I'm convinced that the file tread of Pari-Motos and new Compass tires is the best; it doesn't capture debris like Lierre or Pasela tread.
Steve,
What is the mounted width of the 700c Schwalbe G-ones? I'd love to use the 650b version, but only if they measure 38 mm or less. My 650b-converted Riv Road doesn't fit anything larger.
