I have to agree in part with this. I can see items such as wheelbarrows and some dollies but for a snowblower I want air filled tires. :2cents:My 1971 Ariens tires probably still have 1971 air inside of them..there is no meaningful disadvantage to a tire with air, either tubeless or with a tube.
generally these airless solid tire designs are far less functional that a regular tire with air.
and yes, its been done on snowblowers since the 1950's, for one reason only: making a cheaper snowblower for the lower-end of the lineup.
but manufacturers always need to put a positive spin on cheaper designs! that's just marketing 101.
