toy tire recommendations

I’m looking for toy tires for a project. They should be between 3 and 4 inches in diameter and around an inch thick. All I can find with that diameter are tracter toy tires which are too thick for my purposes. Suggestions? I even hacked off some motorcycle toy bike tires but those are a bit hard (the more shock absorbancy the better).
