For anyone that might care, while Joe didn't have an issue with this, it is a valid question for some of the other kits out there. My brother is doing a Demon with a ControlFreaks kit and it cost him like $1000 each for custom wheels so he could fit a skinny 235 tire under the fender. Not saying he couldn't have found an off the shelf wheel that worked, but it wasn't a common size and the track width of the kit he bought was an issue.
Not pertinent to the HDK kit, but maybe someone will find the info useful.
