Indeed the RTR tires of the fury are not good at all for racing at least. Also the rim is non standard compared with the other SCT's. I wish they would make a compatible rim for third party tires.
That said, 4x4 Slash rims and tires will fit, but not ROAR legal.
I read that article a couple of days ago, what a great read. I love these shootouts that bigsquidrc does, hopefully they will do many more of these in the future.
