Hey guys. Any ideas for a rubber tire rolling sound that does NOT have a motor attached to it? I'm designing some of these rolling guys, and i'm going to use rubber on all of them, but i can't get anything without an engine running. I tried to record just my back tire while my wife was slowly driving my car (they're not moving too fast), and i just don't know if i can make this work for what I need. Any help is appreciated.
Wheel barrows usually have rubber tires on them. Throw some in soft weight that won't bounce (canvas sand bags can be pretty good), rig up your mic to the wheel barrow so you don't have to have someone chasing it, and push that sucker around.
The two wheel variants might be more stable and give you better control with less handling noise.
