The only material property that matters is some sort of ratio of density and elastic modulus, but that'd be the same since ou said it was the same stuff.

So all in all, not surprising your tube wanted to expand more than Spectrum's. Are you guys going for a longer shot to need that much more surface speed?
No just limiting the contact time and wheel size, as well as bad prototypes and the mentality that we will be able to spin slower with a properly built robot that has less friction deficiencies.
