I am working on an animated series for kids about cars (and other vehicles). I use a lot of toy and cartoony sounds for their jumps, fails etc. I also need a good variation of tire rolling sounds. Main characters usually drive on sand and asphalt. I have lots of real tire rolling sounds but they are either too heavy and massive or just don't feel right (too slow, too much rattle etc). I am looking for recommendations on how to fake these sounds in a studio setting. Since it's an animated series, the pace is pretty fast, so I will need to record a good variety of various speed and surfaces rolling sounds, pass bys, approaches etc, in order to be able to cut fast. No budget for foley artist unfortunately. Other than using a small pit with sand (and something else for asphalt) and some round and heavy object to imitate movement I have no thoughts.
Any ideas?
