In other words, in your tests, for the IFI wheels, for a given weight, more contact area gave more friction. This is a fairly common result for high-traction materials on smooth surfaces. Looks like it could apply on carpet too.

Those results, as you so kindly bolded, were
dynamic friction, not
static friction. I don't believe anyone here contested more contact area equating to more dynamic friction. The center of the debate, however, was on the relation between contact area and static friction.
