Bringing the OD down to 1.5" (still black opaque) returns latex tubing with a hardness of 40A, more in-line with what Banebots uses on their wheels.

Is there another supplier where 2" latex tubing is available?

I think this is an error and we are in fact using 1.5" OD latex tubing as you are finding on McMaster.
