Where does one get a 91kg/200lb Huge Tire to use for working out? I was always interested in exercising through chopping wood or using a sledgehammer against a tire. I live in a desert so chopping wood is out - but I have a 10lb sledgehammer.

Where can one buy a ~91kg/200lb Tire in Socal? I tried looking for one on the interet: they're either the wrong tires or these unique stationary half-tire flippers that at least go for $2,500.

Thank you for your times and responses.
