Im surprised nobody mentioned rim size. I bought 2 airless tires and finally figured out my rim width was a mere 12mm. The smallest Tannus tire available was a 13-15mm wide "bead". A quick glance online netted a lot of 15mm +/- 2mm rims. That seems awfully small for a 25c tire, let alone a 19c ( I think that's a retail size).
12mm seems awfully small to be a normal size. Does anyone have any input on "normal" rim width would be? I understand studies are showing wider is better for the footprint of the tire as far as rolling resistance goes.
edit: when I was first starting out using a Cycleops Powerbeam, I never had tire issues. So with a grain of salt, I guess I haven't completely sold myself on the rim size, although for now it seems the most plausible.
