FWIW. I've been running the new Sweep QTS (quick traction system) 32 tires since the beginning of the season. They're certainly improved over last years version, the most significant upgrade IMO is a stiffer wheel. Danny's right, some setup changes may be needed but hey, we all ran the gooey sorex 28's in Edmonton and made out just fine right. If anyone wants the Sweeps in advance to work on setup, PM has them in stock. Looking forward to this race, the KARZ guys put on a great show!
