Honestly, tire companies would love to sell you tires once a year or more, if they were actually safer for the environment, and safe to eat or whatever. I'd happily make that trade-off, if there was legitimate science to back it up. I think about this every time I drive through the morgan hill / gilroy / watsonville area on the way to a camping trip. You have some of the most expensive crops in the nation (berries, leafy greens, cherries, etc.) growing here in california, and it's surrounded by roads that somehow seem like they are always at capacity, depositing tire dust, particulate matter from diesel engines, and who knows what else all over the soil and the plants themselves. This stuff should be just as regulated as if we were spraying it on our crops, because we are.
