Does anyone know of a website that lists the durometer (hardness/softness) of the different manufacturers tires? It would be nice to see an actual comparison on a measured scientific scale such as Shore A or Shore D, rather than just "Brand X is waaaay stickier than Brand Y". I know the different Mags occasionally do "tire shootouts", but by Andrew Trevitts (we wish him a speedy recovery) own admission its been like 6 years since SR has done one.
