I did get the wheels on but they didn't work well so I removed them. To get the wheels off of the front knuckles, the best way in my opinion, is to just twist and pull. I've also had luck with heating up the metal peg with a soldering iron for just a lil bit. Hell you could even just destroy the rim by cutting it off making it easier to pull the peg out of the knuckle, but thats kind of a no return method.
If you search the boards for wheel swaps you should be able to find alot more info.
