I was ready to buy a set of skat-traks but thought I should look through this forum first. I read a post mentioning that skat-trak was researching a tire for the DS. I called someone there that said that a new tire with heavier duty paddles should be available this fall. This will be in addition to their regular tires, not revamping their entire line. Thought I should post this for all those like me who buy something only to see something newer or better come out right away.
