old tires, this is a great topic. i'm sure many of you have seen those photos of old tire dumps where the tires go on forever. i still have not heard of a good solution for the reuse or recycling of old tires. i think that goes for bicycle tires as well (they are basically made the same way)
i always feel guilty, like last week when i took a small stack of old tires out to the dump. i bet some kids in a 3rd world country would have found my 'used' tires to be in great condition
