I am using CRC High Rollers. At first, I wasn't sure which tire compounds came in the kit (Gen-X kit, purple and grey). I also tried the new Jaco, but I like the feel of the kit tires the best.
The Jaco Prizm rim is so soft, plus I ripped one off the left hub on what I think was a very light hit. Looking closely at the rims, it appears that the CRC wheel has more plastic bracing around the wheel mounting holes. The ribs flow into the wheel mounting holes on the CRC wheel. The Jaco wheel mounting area is just plain with no gussetting or bracing from the ribs.
I will be sticking with the High Rollers, maybe at some point I will try the Parmas.
