Hi Polaris Obark, that's good to hear. And good for safety. If you puncture you'll have time to notice before the tire rolls off the bead - it won't roll off immediately. Can you clarify which rims you purchased? Thanks!

For reference:
- With the RM29C06d, which they rebadged as the Falcon AR24 for gravel usage: If the pressure drops below 5 or 10 PSI with gravel tires, the tires will just fall off the bead (even when suspended in the air, nothing touching them, on the bike stand). That's the opposite of my Stan's Grail wheelset where there is a more prominent "bead hump" and you have to physically push the same tire off the bead. The same tires would never fall off the bead by itself.
- When topping up sealant, I often have to use an Air Shot canister and ensure that the valve core is removed to get enough of a blast of air into the tires to reseat them. On other wheelsets (Stan's Grail, stock no-name wheelset, Prime Kanza/Orra) the tires stay on the bead and can be fully reseated with a normal floor pump without much effort.
- I can work with this situation (and have for a long time), but it does mean you will be putting in a tube if you can't plug a puncture fast enough when on the road or trail. You certainly won't be reseating the tire with a mini pump and it would be maybe 50/50 chance with a CO2 cartridge, since you don't get the benefit of faster air flow by having the valve core removed.

Okay... I hope that explains. These are one of Light Bicycle's older rim models, so I hope/suspect that newer models have a different rim profile.
