currently we are using Shinko Moped tires, this is more for cost cutting though, as with the harder compound ive been running our technical tracks down here in tampa, and im fairly confident i can get though the entire season on 1 set of tires. I find the grip to be about the same as i was previously using hookworms. They are thicker though, so you might loose a bit in terms of rolling resistance. But for the cost saved, its a really good option, as 3 shinko tires were $70 that lasts the entire season, compared to our previous usage of about 24-30 ($407-$509) hookworms for 1 season .
